DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0113] Hereinafter, an image processing apparatus, an upgrade
apparatus, a display system, and a control method thereof according
to exemplary embodiments will be described in detail with reference
to accompanying drawings.
[0114] In the exemplary embodiments, an "image processing
apparatus" refers to a display device which processes an image
signal and may include a display unit to display an image based on
an image signal internally or output a processed image signal to an
external display apparatus without including a display unit
internally. The image processing apparatus according to the
exemplary embodiments include both types. A display device which
processes an image signal and includes a display unit to display an
image based on an image signal is also referred to as a "display
apparatus" hereinafter.
[0115] Referring to FIG. 1, a display system 1 according to an
exemplary embodiment includes an image processing apparatus 100
processing an image signal provided from an external image source
(not shown) according to a preset image processing process to
display an image and an upgrade apparatus 200 upgrading hardware or
software of the image processing apparatus 100.
[0116] In the display system 1 according to the exemplary
embodiment, the image processing apparatus 100 is configured as a
TV which displays a broadcast image based on a broadcast signal,
broadcast information or broadcast data received from a transmitter
of a broadcasting station. The image processing apparatus 100 may
be configured as various types of devices which process an image or
process and display an image, without being limited to a TV. For
example, the image processing apparatus 100 may be a set-top box
which performs image processing only and does not display an
image.
[0117] The image processing apparatus 100 may display any type of
image, without being limited to a broadcast image. For example, the
image processing apparatus 100 may display images, such as videos,
still images, applications, an on-screen display (OSD) based on
signals or data received from various types of image sources (not
shown), and a graphic user interface (GUI) for controlling various
operations.
[0118] The upgrade apparatus 200 is connected to the image
processing apparatus 100 so as to communicate with the image
processing apparatus 100. The upgrade apparatus 200 upgrades
existing hardware or software of the connected image processing
apparatus 100 and enables an image signal to be processed by the
upgraded hardware or software of the image processing apparatus
100, thereby displaying an image with improved quality.
[0119] As shown in FIG. 1, the image processing apparatus 100
includes a first signal input unit 110 receiving an image signal
from at least one image source (not shown), a first image
processing unit 130 processing the input signal from the first
signal input unit 110 and outputting a first output signal, an
upgrade apparatus connection unit 160 to which the upgrade
apparatus 200 including a second image processing unit 220 is
connected, and a first controller 140 controlling the first image
processing unit 130.
[0120] The first signal input unit 110 transmits an image signal
and/or a broadcast signal received from at least one image source
to the first image processing unit 130. The first signal input unit
110 may include a tuner to receive a broadcast signal.
[0121] An image signal received through the first signal input unit
110 may have various standards depending on an image source and a
display mode of and a display unit 170. For example, the first
signal input unit 110 may receive signals or data in accordance
with a high definition multimedia interface (HDMI), a universal
serial bus (USB), and component standards and include a plurality
of connection terminals (not shown) corresponding to the respective
standards. Various types of external devices including the image
source may be connected to the connection terminals, thus receiving
an image signal through the first signal input unit 110.
[0122] When the upgrade apparatus 200 is connected to the upgrade
apparatus connection unit 160, the first signal input unit 110 may
be configured to transmit the input signal to the upgrade apparatus
connection unit 160, and not to the first image processing unit 130
according to control of the controller 140. That is, the first
signal input unit 110 may include a plurality of output ports to
receive and output the input signal and thus selectively transmit
the input signal to either the upgrade apparatus 200 or the first
image processing unit 130 according to control of the controller
140. The first signal input unit 110 may be configured to provide
the input signal only to the first image processing unit 130.
[0123] The first image processing unit 130 may include a
demultiplexer (not shown), which performs demultiplexing by
separating a broadcast signal received from the first signal input
unit 110 into an image signal, an audio signal and optional data, a
decoder (not shown) decoding the separated image signal into a
predetermined image format, and a scaler (not shown) scaling the
decoded image signal to a predetermined resolution to display an
image based on the image signal on the display unit 170.
[0124] Further, the first image processing unit 130 may perform
various preset image processing processes on an image signal
received from the first signal input unit 110. The first image
processing unit 130 outputs a processed image signal to the display
unit 170, so that an image based on the image signal is displayed
on the display unit 170.
[0125] The first image processing unit 130 may perform any type of
image processing, without being limited to, for example,
demultiplexing to separate a signal into characteristic signals,
decoding in accordance with an image format of an image signal,
de-interlacing to convert an interlaced image signal into a
progressive form, scaling to adjust an image signal to a preset
resolution, noise reduction to improve image quality, detail
enhancement, frame refresh rate conversion, or the like.
[0126] The first image processing unit 130 may be provided as an
image processing board (not shown) in which a circuit system
including various chip sets (not shown), a memory (not shown),
electronic components (not shown) and wiring (not shown) to conduct
such processes is mounted on a printed circuit board (PCB, not
shown).
[0127] Meanwhile, the upgrade apparatus connection unit 160 is
connected to a body connection unit 210 of the upgrade apparatus
200 so that the image processing apparatus 100 and the upgrade
apparatus 200 communicate at least one of data, a signal,
information and power with each other.
[0128] The upgrade apparatus connection unit 160 may transmit at
least one of the input signal input through the first signal input
unit 110 and the first output signal output by the first image
processing unit 130 to the body connection unit 210.
[0129] Here, the first output signal may include at least one of a
first image signal and a first audio signal.
[0130] The upgrade apparatus connection unit 160 may be configured
as a connection port in accordance with a general standard, such as
an HDMI, USB or component port. As necessary, the upgrade apparatus
connection unit 160 may be configured to communicate data, a
signal, information/, or power in accordance with a low voltage
differential signaling (LVDS) standard.
[0131] The upgrade apparatus connection unit 160 may be provided in
any type and form, without being limited to the foregoing examples,
as long as it is configured to enable the image processing
apparatus 100 and the upgrade apparatus 200 to communicate at least
one of data, a signal, information, and power with each other.
[0132] When the upgrade apparatus 200 is not connected to the
upgrade apparatus connection unit 160, the upgrade apparatus
connection unit 160 transmits the first image signal output by the
first image processing unit 130 to the display unit 170.
[0133] The upgrade apparatus connection unit 160 may receive a
second output signal processed by the second image processing unit
220 through the body connection unit 210 of the upgrade apparatus
200 and transmit the received second output signal to the display
unit 170.
[0134] As necessary, when the upgrade apparatus 200 is configured
to output the second output signal directly to the display unit
170, and not via the image processing apparatus 100, the upgrade
apparatus connection unit 160 does not receive the second output
signal from the upgrade apparatus 200.
[0135] The upgrade apparatus connection unit 160 may enable
communication of a control instruction between the first controller
140 and a second controller 230 of the upgrade apparatus 200. That
is, the upgrade apparatus connection unit 160 may have a connection
port for transmitting and receiving the control instruction.
[0136] Meanwhile, when the upgrade apparatus 200 is not connected
to the upgrade apparatus connection unit 160, the first controller
140 controls the first image processing unit 130 to process the
input signal.
[0137] When the upgrade apparatus 200 is connected to the upgrade
apparatus connection unit 160, the first controller 140 controls
the first signal input unit 110 and the first image processing unit
130 such that at least one of the input signal and the first output
signal is transmitted to the upgrade apparatus 200 through the
upgrade apparatus connection unit 160 and is processed by the
second image processing unit 220.
[0138] The first controller 140 may detect whether the upgrade
apparatus 200 is connected through the upgrade apparatus connection
unit 160.
[0139] When the second output signal processed by the upgrade
apparatus 200 is received by the upgrade apparatus connection unit
160 through the body connection unit 210, the first controller 140
may control the upgrade apparatus connection unit 160 to transmit
the second output signal to the display unit 170.
[0140] The image processing apparatus 100 may further include the
display unit 170 to display at least one of a first image
corresponding to the first output signal and a second image
corresponding to the second output signal processed and output by
the second image processing unit 220 of the upgrade apparatus
200.
[0141] That is, when the upgrade apparatus 200 is not connected to
the upgrade apparatus connection unit 160, the display unit 170
displays the first image corresponding to the first output signal
output by the first image processing unit 130. When the upgrade
apparatus 200 is connected to the upgrade apparatus connection unit
160, the display unit 170 displays the second image corresponding
to the second output signal output by the second image processing
unit 220.
[0142] The display unit 170 may be configured in various display
modes using liquid crystals, plasma, light emitting diodes, organic
light emitting diodes, a surface conduction electron emitter, a
carbon nano-tube, nano-crystals, or the like, without being limited
thereto.
[0143] The display unit 170 may further include an additional
element depending on a display mode thereof. For example, in a
display mode using liquid crystals, the display unit 170 may
include a liquid crystal display (LCD) panel, a backlight unit (not
shown) providing light to the panel, and a panel drive board (not
shown) driving the panel.
[0144] Further, the image processing apparatus 100 may further
include a conversion-amplification unit 180 converting an audio
signal separated by the first image processing unit 130 into a
preset format and amplifying the signal, and an audio output unit
190 outputting the amplified audio signal. Here, the audio output
unit 190 may include a speaker.
[0145] Also, the image processing apparatus 100 may further include
a user input unit 120 outputting a preset command according to
manipulation by a user, and a first storage unit 150 storing
unlimited data or information.
[0146] The user input unit 120 transmits various preset control
commands or unlimited information to the first controller 140 based
on a user's manipulation and input. The user input unit 120 may be
provided as a menu key and an input panel installed on an outside
of the image processing apparatus 100 or as a remote controller
separate from the image processing apparatus 100.
[0147] The user input unit 120 may be configured to communicate
with the image processing apparatus 100 using a short-range
wireless communication method, such as Bluetooth or infrared
communication. In this case, the user input unit 120 may include a
wireless keyboard, a wireless mouse, or the like as well as the
remote controller.
[0148] As necessary, the user input unit 120 may be configured as a
single body with the display unit 170. That is, if the display unit
170 is a touch screen, a user may transmit a preset command to the
first controller 140 through an input menu (not shown) displayed on
the display unit 170.
[0149] The first storage unit 150 may store unlimited data
according to control of the first controller 140. The first storage
unit 150 may be configured as a non-volatile memory, such as a
flash memory and a hard disk drive. The first storage unit 150 is
accessible by the first controller 140, and the data stored in the
first storage unit 150 may be read, recorded, revised, deleted, or
updated by the first controller 140.
[0150] The first storage unit 150 may store, for example, an
operating system to run the image processing apparatus 100 and
various applications, image data, and optional data which are
executable in the operating system.
[0151] The first controller 140 performs control operations over
various components of the image processing apparatus 100. For
example, the first controller 140 conducts image processing by the
first image processing unit 130, transmission or reception
operations of signals, information, or data through the first
signal input unit 110, and a control operation corresponding to a
command from the user input unit 120, thereby controlling the
overall operation of the image processing apparatus 100.
[0152] The upgrade apparatus 200 may be connected to the image
processing apparatus 100 via wire or wirelessly. In the exemplary
embodiment, the upgrade apparatus 200 and the image processing
apparatus 100 may be connected to each other via wire to transmit
and receive data, information, signals, or power. As described
above, the upgrade apparatus 200 includes the body connection unit
210 to transmit or receive power and data to or from the image
processing apparatus 100, and the image processing apparatus 100
includes the upgrade apparatus connection unit 160 to transmit or
receive power and data to or from the upgrade apparatus 200. That
is, the upgrade apparatus 200 may receive power needed for driving
from the image processing apparatus 100 through the body connection
unit 210. When necessary, the upgrade apparatus 200 may further
include a power conversion unit (not shown) to convert power input
from the image processing apparatus 100 into power needed for
driving.
[0153] The upgrade apparatus 200 may be supplied with driving power
needed to operate from a separate external power source (commercial
power source or battery) and not directly from the image processing
apparatus 100 through the body connection unit 210
[0154] Further, unlike in FIG. 1, the upgrade apparatus 200 may be
connected to the image processing apparatus 100 wirelessly if
necessary. In this case, the upgrade apparatus 200 may be supplied
with operation power from a separate external power source or
battery, and not from the image processing apparatus 100.
[0155] Until the upgrade apparatus 200 is connected to the image
processing apparatus 100, the image processing apparatus 100
autonomously processes an image signal received from outside of the
image processing apparatus 100 according to a preset image
processing process and displays an image based on the signal.
However, when the upgrade apparatus 200 is connected to the image
processing apparatus 100, hardware or software configurations of
the display system 1 performing the above image processing process
are upgraded. Accordingly, new functions or updated functions may
be provided to a user due to the upgrade apparatus 200. For
example, as the upgrade apparatus 200 is connected, there is
provided an image with higher quality than that realized by the
image processing apparatus 100 alone.
[0156] The upgrade apparatus 200 includes the body connection unit
210 connected to the image processing apparatus 100, the second
image processing unit 220 receiving and processing a signal output
from the image processing apparatus 100 through the body connection
unit 210, and a second controller 230 controlling the second image
processing unit 220.
[0157] When the second image processing unit 220 is configured to
be controlled only by the first controller 140 of the image
processing apparatus 100, the second controller 230 may be omitted
as necessary.
[0158] The second image processing unit 220 processes any input
signal of the first signal input unit 110 output from the image
processing apparatus 100 and the first output signal output from
the first image processing unit 130 and outputs the signal as a
second output signal.
[0159] The second output signal output by the second image
processing unit 220 is transmitted to the display unit 170 through
the body connection unit 210 and the upgrade apparatus connection
unit 160. Accordingly, a second image corresponding to the second
output signal may be displayed on the display unit 170. Since the
second image processing unit 220 additionally performs a function
upgraded from a function of the first image processing unit 130 or
a function which cannot be conducted by the first image processing
unit 130, an upgraded image which is not realized by the image
processing apparatus 100 or is hard to be realized by the image
processing apparatus 100 is displayed on the display unit 170.
[0160] For example, a full HD image cannot be provided by the first
image processing unit 130, but may be provided by the second image
processing unit 220. Further, a 3D image cannot be realized by the
first image processing unit 130, but may be presented through the
second image processing unit 220. Such added and expanded functions
are only illustrative examples and are not limited to these
examples.
[0161] Here, the second image processing unit 220 may reprocess the
audio signal as well as the image signal, and accordingly the
reprocessed and upgraded audio signal may be provided to the image
processing apparatus 100.
[0162] Meanwhile, the upgrade apparatus 200 may further include a
second signal input unit 250 receiving a broadcast signal or an
image signal from an image source and transmitting the signal to
the second image processing unit 220.
[0163] In the foregoing exemplary embodiment, the broadcast signal
or the image signal is received or input through the first signal
input unit 110 of the image processing apparatus 100. However, if
needed, the upgrade apparatus 200 may include the second signal
input unit 250 to receive a broadcast signal or an image signal
separately from the image processing apparatus 100. In this case,
when it is detected that the upgrade apparatus 200 is connected to
the upgrade apparatus connection unit 160, the first controller 140
of the image processing apparatus 100 may stop operations of the
first signal input unit 110 and the first image processing unit
130. Here, an input signal (broadcast signal or image signal) input
through the second signal input unit 250 is transmitted to the
second image processing unit 220 and processed, and a second output
signal output by the second image processing unit 220 may be
transmitted to the display unit 170 through the upgrade apparatus
connection unit 160 of the image processing apparatus 100.
Accordingly, a second image corresponding to the second output
signal may be displayed on the display unit 170.
[0164] In another exemplary embodiment, when the upgrade apparatus
200 independently receives a broadcast signal or an image signal
through the second signal input unit 250, the first controller 140
may control the first image processing unit 130 to process a signal
input through the first signal input unit 110 and output a first
output signal to the display unit 170. Here, the display unit 170
may display a first image corresponding to the first output signal
as a main screen or sub-screen. At the same time, when receiving
the broadcast signal or image signal through the second signal
input unit 250, the upgrade apparatus 200 processes the signal in
the second image processing unit 220 and transmits a second output
signal to the display unit 170. Accordingly, the display unit 170
may display a second image corresponding to the second output
signal as a sub-screen or main screen in accordance with the first
image. That is, the first input signal input through the first
signal input unit 110 of the image processing apparatus 100 and the
second input signal input through the second signal input unit 250
of the upgrade apparatus 200 are processed into the first image and
the second image, respectively, which may be then displayed in
picture in picture (PIP) on the display unit 170.
[0165] When it is detected that the upgrade apparatus 200 is
connected, the first controller 140 of the image processing
apparatus 100 may control the first image processing unit 130 and
the first signal input unit 110 in cooperation with the second
controller 230 of the upgrade apparatus 200. For example, the first
controller 140 may be responsible for controlling part of the
demultiplexer (not shown), the decoder (not shown) and the scaler
(not shown) of the first image processing unit 130, and the second
controller 230 may be responsible for controlling the rest
thereof.
[0166] If necessary, the first controller 140 may have priority to
control the first signal input unit 110 and the first image
processing unit 130, and the second controller 230 may assist the
first controller 140.
[0167] In another exemplary embodiment, the second controller 230
may have priority to control the first signal input unit 110 and
the first image processing unit 130, and the first controller 140
may assist the second controller 230.
[0168] Meanwhile, when it is detected that the upgrade apparatus
200 is connected, the first controller 140 of the image processing
apparatus 100 may entirely transfer the control function of the
first controller 140 to the second controller 230. Here, the first
controller 140 does not give a control instruction, but just
delivers a control instruction between a subject controlled

[0202] The signal connection member 168 includes a signal
connection terminal 168a disposed between the first input signal
terminal 161b and the display unit output terminal 163b to
electrically connect these two terminals. Accordingly, until the
upgrade apparatus 200b is inserted into the upgrade apparatus
connection unit 160b, the first output signal processed by the
first image processing unit 130 may be transmitted to the display
unit 170 by the signal connection member 168.
[0203] Meanwhile, the upgrade apparatus 200b includes a body
connection unit 210a receiving the first output signal from the
first input signal terminal 161b and transmitting a second output

[0206] To connect the upgrade apparatus 200b to the upgrade
apparatus connection unit 160b, the signal connection member 168 is
removed from the upgrade apparatus connection unit 160b, and then
the body connection unit 210a of the upgrade apparatus 200b is
inserted into the upgrade apparatus connection unit 160b.
[0207] Referring to FIG. 5, a display system 1c according to an
exemplary embodiment includes an upgrade apparatus 200b and an
image processing apparatus 100c functionally upgraded when the
upgrade apparatus 200b is connected thereto.
[0208] The image processing apparatus 100c includes a data
distribution unit 178 distributing a first image signal output by a
first image processing unit 130 to an upgrade apparatus connection
unit 160 and a data selection unit 169, the data selection unit 169
selecting any one of a second image signal output through the
upgrade apparatus connection unit 160 and the first image signal
distributed by the data distribution unit 178, and a first
controller 140 controlling the data distribution unit 178 and the
data selection unit 169.
[0209] The data distribution unit 178 may include a demultiplexer
distributing the first image signal into a plurality of output
signals by a control signal of the first controller 140.
[0210] The data selection unit 169 may include a multiplexer
selecting any one of the first image signal and the second image
signal by a control signal of the first controller 140.
[0211] The first controller 140 controls the data distribution unit
178 and the data selection unit 169 to output the first output
signal output from the first image processing unit 130 to a display
unit 170 when the upgrade apparatus 200b is not connected to the
image processing apparatus 100c. Here, as described above, the
first output signal includes at least one of the first image signal
and a first audio signal.
[0212] In detail, when the upgrade apparatus 200b is not connected
to the upgrade apparatus connection unit 160, the first controller
140 controls the data distribution unit 178 to distribute the first
image signal output by the first image processing unit 130 to the
data selection unit 169. Further, the first controller 140 controls
the data selection unit 169 to select the first image signal output
from the data distribution unit 178 and output the signal to a
display connection unit 173. Accordingly, a first image
corresponding to the first image signal may be displayed on the
display unit 170.
[0213] When the upgrade apparatus 200b is connected, the first
controller 140 controls the data distribution unit 178 and the data
selection unit 169 to distribute the first output signal output
from the first image processing unit 130 to the upgrade apparatus
connection unit 160 and to output a second output signal output by
the upgrade apparatus 200b to the display unit 170.
[0214] In detail, when the upgrade apparatus 200b is connected to
the upgrade apparatus connection unit 160, the first controller 140
controls the data distribution unit 178 to distribute the first
image signal output by the first image processing unit 130 to the
upgrade apparatus connection unit 160. Accordingly, the first image
signal transmitted to the upgrade apparatus connection unit 160 is
input to a second image processing unit 220 through a body
connection unit 210a. The second image processing unit 220
processes the input first image signal to output a second image
signal, and the output second image signal is input to the data
selection unit 169 through the body connection unit 210a and the
upgrade apparatus connection unit 160. The data selection unit 169
selects and outputs the second image signal to the display
connection unit 173 according to a control instruction of the first
controller 140. Accordingly, a second image corresponding to the
second image signal may be displayed on the display unit 170. Here,
the second image signal may be functionally improved as compared
with the first image signal or may have a newly added function
which the first image signal does not have.
[0215] Accordingly, a user may watch an upgraded image by mounting
the upgrade apparatus 200b to the image processing apparatus
100c.
[0216] When the upgrade apparatus 200b is connected to the upgrade
apparatus connection unit 160, the first output signal output by
the first image processing unit 130 may be input to the second
image processing unit 220 through the upgrade apparatus connection
unit 160, thereby outputting the second output signal.
[0217] Here, the first output signal may include the first audio
signal as well as the first image signal.
[0218] The first audio signal is input to the second image
processing unit 220 through the upgrade apparatus connection unit
160 and processed by the second image processing unit 220, thereby
outputting a second audio signal. The second audio signal output by
the second image processing unit 220 may be output to an audio
output unit 190 via the upgrade apparatus connection unit 160, the
first image processing unit 130, and a conversion-amplification
unit 180.
[0219] In the foregoing exemplary embodiment, the data distribution
unit 178 and the data selection unit 169 are controlled by the
first controller 140. However, as necessary, a second controller
230 of the upgrade apparatus 200b may control the data distribution
unit 178 and the data selection unit 169 to perform the same
functions described above.
[0220] Referring to FIG. 6, a display system 1d according to an
exemplary embodiment includes an upgrade apparatus 200b and an
image processing apparatus 100d to which the upgrade apparatus 200b
is connected.
[0221] The image processing apparatus 100d includes a first image
processing unit 130a processing an input signal input through a
first signal input unit 110 and outputting a first image signal
through a first output port 130a1 and a second output port 130a2,
an upgrade apparatus connection unit 160b receiving the first image
signal output from the first output port of the first image
processing unit 130a, and an image signal switch 165 selectively
transmitting the first image signal output from the second output
port of the first image processing unit 130a to the display unit
170.
[0222] In the exemplary embodiment shown in FIG. 4, the signal
connection member 168 is inserted into the upgrade apparatus
connection unit 160b before the upgrade apparatus 200 is connected
to the upgrade apparatus connection unit 160b. However, in the
present exemplary embodiment, a signal connection member 168 is not
inserted into the upgrade apparatus connection unit 160b before the
upgrade apparatus 200 is connected thereto.
[0223] That is, until the upgrade apparatus 200b is not connected,
a first input signal terminal 161b and a display unit output
terminal 163b of the upgrade apparatus connection unit 160b do not
short-circuit, but are physically open. Accordingly, a first output
signal by the first image processing unit 130 input to the first
input signal terminal 161b is not output to the display unit 170
through the display unit output unit 163b.
[0224] When the upgrade apparatus 200b is not connected to the
upgrade apparatus connection unit 160b, a first controller 140
turns on the image signal switch 165 so that the first image signal
is transmitted to the display unit 170, specifically to a display
connection unit 173. Accordingly, a first image corresponding to
the first image signal is displayed on the display unit 170.
[0225] When it is detected that the upgrade apparatus 200b is
connected to the upgrade apparatus connection unit 160b, the first
controller 140 turns off the image signal switch 165 so that the
first image signal is not transmitted directly to the display unit
170. Accordingly, the first image signal input to the upgrade
apparatus connection unit 160b may be transmitted to the upgrade
apparatus 200b through a body connection unit 210a and processed by
a second image processing unit 220. A second image signal processed
by the second image processing unit 220 is transmitted to the
display unit 170 through the upgrade apparatus connection unit
160b. Accordingly, a second image corresponding to the second image
signal may be displayed on the display unit 170.
[0226] Here, the image signal switch 165 may be configured as a
switch suitable for an electrical signal system capable of
operating at a high speed in accordance with low voltage
differential signaling (LVDS). The image signal switch 165 may be
configured as a bus switch capable of transmitting data at a high
speed.
[0227] Referring to FIG. 7, a display system 1e according to an
exemplary embodiment includes an upgrade apparatus 200b and an
image processing apparatus 100e to which the upgrade apparatus 200b
is connected.
[0228] Compared with the previous exemplary embodiment, the image
processing apparatus 100e according to the present exemplary
embodiment includes a first image processing unit 130 processing an
input signal input through a first signal input unit 110 to output
a first image signal through a single output port.
[0229] The first image signal output through the single output port
of the first image processing unit 130 is divided and input to an
upgrade apparatus connection unit 160b and an image signal switch
165.
[0230] The other elements of the display system 1e in the present
exemplary embodiment are the same as those of the display system 1d
in the previous exemplary embodiment, and thus descriptions thereof
are omitted herein.
[0231] Referring to FIGS. 8, 9 and 10, a display system 1f
according to an exemplary embodiment includes an upgrade apparatus
200b and an image processing apparatus 100f to be upgraded when the
upgrade apparatus 200b is connected to the image processing
apparatus 100f.
[0232] The image processing apparatus 100f includes an upgrade
apparatus connection unit 160c selectively transmitting any one of
a first output signal output from a first image processing unit 130
and a second output signal output from a second image processing
unit 220 to a display unit 170 depending on whether the upgrade
apparatus 200b is inserted or is not inserted into the image
processing apparatus 100f.
[0233] The upgrade apparatus connection unit 160c according to the
present exemplary embodiment is configured to switch the first
output signal and the second output signal alone without the signal
connection member 168 in FIG. 4, the data distribution unit 178,
the data selection unit 169, and the image signal switch 165 which
are provided to selectively transmit the first output signal and
the second output signal to the display unit 170 in the foregoing
exemplary embodiments.
[0234] The upgrade apparatus connection unit 160c includes a first
input signal terminal 161c to which the first output signal output
from the first image processing unit 130 is input, and a display
unit output terminal 163c to be selectively brought in contact with
any one of the first input signal terminal 161c and a body
connection unit 210 of the upgrade apparatus 200b based on whether
the upgrade apparatus 200b is connected so that any one of the
first output signal and the second output signal is output to the
display unit 170.
[0235] Here, at least one of the first input signal terminal 161c
and the display unit output terminal 163c may be configured to move
in an approach direction to be brought in contact with the other
thereof when the upgrade apparatus 200b is not connected and to
move back in a receding direction to be brought out of contact with
the other thereof when the upgrade apparatus 200b is connected.
[0236] In detail, as shown in FIGS. 9 and 10, a first contact unit
161c1 of the first input signal terminal 161c and a second contact
unit 163c1 of the display unit output terminal 163c move close to
each other to be in contact with each other when the upgrade
apparatus 200b is not inserted.
[0237] Here, the image processing apparatus 100f may further
include an elastic member 165c to provide elastic biasing force F1
and F2 to at least one of the first input signal terminal 161c and
the display unit output terminal 163c so that the first input
signal terminal 161c and the display unit output terminal 163c are
brought in contact with each other when the upgrade apparatus 200b
is not connected to the upgrade apparatus connection unit 160c.
[0238] When a body connection unit 210a of the upgrade apparatus
200b is inserted between the first input signal terminal 161c and
the display unit output terminal 163c, the first input signal
terminal 161c and the display unit output terminal 163c move in the
receding direction so that the first contact unit 161c1 and the
second contact unit 163c1 are spaced away from each other. Then,
the first input signal terminal 161c is brought in contact with an
input terminal (not shown) of the body connection unit 210a and the
display unit output terminal 163c is brought in contact with an
output terminal 212 of the body connection unit 210a. Accordingly,
the first output signal is input through the input terminal of the
body connection unit 210a, processed by the second image processing
unit 220, and then output as the second output signal to the
display unit output terminal 163c through the output terminal 212
of the body connection unit 210a.
[0239] Thus, when the upgrade apparatus 200b is not inserted into
the upgrade apparatus connection unit 160c, the first output signal
may be transmitted to the display unit 170 through the display unit
output terminal 163c. Further, when the upgrade apparatus 200b is
inserted into the upgrade apparatus connection unit 160c, the
second output signal may be transmitted to the display unit 170
through the display unit output terminal 163c.
[0240] Here, the body connection unit 210a may include a first
surface 213 facing the first input signal terminal 161c and a
second surface 214 facing the display unit output terminal 163c,
wherein the input terminal may be provided on the first surface 213
and the output terminal 212 may be provided on the second surface
214.
[0241] Although FIGS. 9 and 10 illustrate that both the first input
signal terminal 161c and the display unit output terminal 163c move
close to or away from each other, as necessary, any one of the
first input signal terminal 161c and the display unit output
terminal 163c can be fixed while the other thereof moves back and
forth.
[0242] Further, although FIGS. 9 and 10 illustrate that at least
one of the first input signal terminal 161c and the display unit
output terminal 163c moves, as necessary, the first input signal
terminal 161c and the display unit output terminal 163c do not have
to move and can be formed of a transformable elastic material. In
this case, when the body connection unit 210a is inserted, the
first input signal terminal 161c and the display unit output
terminal 163c are transformed by contact with the body connection
unit 210a, thereby bringing the first input signal terminal 161c
and the display unit output terminal 163c out of contact with each
other.

[0246] FIGS. 16 and 17 are perspective views illustrating a
connection of an upgrade apparatus connection unit of an image
processing apparatus and an upgrade apparatus according to an
exemplary embodiment. As shown in FIG. 16, a body connection unit
2101 of an upgrade apparatus 200 includes a terminal unit 2102. As
shown in FIG. 17, the body connection unit 2101 may be inserted
into an upgrade apparatus connection unit 1604 of an image
processing apparatus 100.
[0247] Referring to FIG. 18, a display system 1g according to an
exemplary embodiment includes an upgrade apparatus 200b and an
image processing apparatus 100g upgraded by the upgrade apparatus
200b.
[0248] Compared with the display system 1e of FIG. 7, the image
processing apparatus 100g of the display system 1g according to the
present exemplary embodiment further includes a wireless user input
unit 120a, a wireless communication unit 183, a camera unit 185,
and a control path conversion switch 187.
[0249] The wireless user input unit 120a is to receive a control
input signal wirelessly from a user and may include a remote
controller, a wireless keyboard, and a wireless mouse.
[0250] The wireless user input unit 120a may be configured to
communicate with the image processing apparatus 100g using a
short-range communication method, such as Bluetooth or infrared
communication.
[0251] The wireless communication unit 183 is used to access an
Internet network wirelessly and may include a wireless
communication module in accordance with at least one wireless
communication technology among Wi-Fi, WiBro and Long Term Evolution
(LTE).
[0252] The camera unit 185 is used to take an image and may include
an image sensor (not shown) and an optical lens (not shown).
[0253] The control path conversion switch 187 selects either a
first controller 140 or the upgrade apparatus 200b to have control
over at least one of the wireless user input unit 120a, the
wireless communication unit 183 and the camera unit 185 based on
whether the upgrade apparatus 200b is connected.
[0254] When the upgrade apparatus 200b is not connected to an
upgrade apparatus connection unit 160b, the first controller 140
controls the wireless user input unit 120a, the wireless
communication unit 183 and the camera unit 185.
[0255] However, when the upgrade apparatus 200b is connected to the
upgrade apparatus connection unit 160b, the first controller 140
may stop controlling at least one of the wireless user input unit
120a, the wireless communication unit 183 and the camera unit 185.
Instead of the first controller 140, a second controller 230 of the
upgrade apparatus 220b may directly control at least one of the
wireless user input unit 120a, the wireless communication unit 183
and the camera unit 185 by the control path conversion switch
187.
[0256] Internal elements to be quickly processed or controlled,
such as user input, Internet data and a taken image signal received
through the wireless user input unit 120a, the wireless
communication unit 183 and the camera unit 185, may need to be
connected directly to the second controller 230 instead of
communicating with the second controller 230 via the first
controller 140. In this case, when the upgrade apparatus 200b is
connected to the image processing apparatus 100g, the control path
conversion switch 187 is controlled to form a control path directly
connecting the second controller 230 and at least one of the
wireless user input unit 120a, the wireless communication unit 183
and the camera unit 185.
[0257] Meanwhile, when the upgrade apparatus 200b is not connected,
a control path is formed such that the wireless user input unit
120a, the wireless communication unit 183 and the camera unit 185
are controlled by the first controller 140.
[0258] The control path conversion switch 187 may be controlled by
at least one of the first controller 140 and the second controller
230 of the upgrade apparatus 200b. When the first controller 140
and the second controller 230 control the control path conversion
switch 187 together, at least one of control instructions of the
first controller 140 and the second controller 230 is given
priority. For example, the first controller 140 has main control
and the second controller 230 has auxiliary control, and vice
versa.
[0259] Hereinafter, an image processing apparatus (display
apparatus), an upgrade apparatus, a display system, and a control
method thereof according to another exemplary embodiment will be
described. In the present exemplary embodiment, descriptions of
components which are the same as or similar to those of the image
processing apparatuses 100 to 100g, the upgrade apparatuses 200 to
200g, and the display systems 1 to 1g described with reference to
FIGS. 1 to 18 will be omitted herein. FIG. 19 is a block diagram of

to the display apparatus 22100 via wire or wirelessly.
[0269] The display apparatus 22100 may autonomously process an
image signal received from the outside according to a preset image
processing process and display an image based on the signal.
However, in the present exemplary embodiment, as the display
apparatus 22100 and the upgrade apparatus 22200 are connected to
each other, hardware or software configurations of the display
system 221 performing the above image processing process are
upgraded. Accordingly, an image with relatively enhanced quality or
an image with a newly added function may be provided to a user.
[0270] Hereinafter, configurations of the display apparatus 22100
and the upgrade apparatus 22200 will be described with reference to
FIGS. 20 and 21.
[0271] As shown in FIG. 20, the display apparatus 22100 includes a

processed by the image processing unit 22120, a user input unit
22170, the storage unit 22150 storing data or information, the
connection unit 22130 connected to the upgrade apparatus 22200, and
the controller 22110 controlling operations of all components of
the display apparatus 22100.
[0272] The signal input/output unit 22140 transmits a received
image signal to the image processing unit 22120 and is configured
in various types in accordance with standards of received signals
and formats of the image source and the display apparatus 22100.
For example, the signal input/output unit 22140 may receive
signals/data in accordance with HDMI, USB, and component standards
and include a plurality of connection terminals (not shown)
corresponding to the respective standards.
[0273] The image processing unit 22120 may perform various preset
image processing processes on an image signal received from the
signal input/output unit 22140. The image processing unit 22120
outputs a processed image signal to the display unit 22160, so that
an image based on the image signal is displayed on the display unit
22160.
[0274] The image processing unit 22120 may perform any type of
image processing, without being limited to, for example,
demultiplexing to separate a signal into characteristic signals,
decoding in accordance with an image format of an image signal,
de-interlacing to convert an interlaced image signal into a
progressive form, scaling to adjust an image signal to a preset
resolution, noise reduction to improve image quality, detail
enhancement, frame refresh rate conversion, or the like.
[0275] The image processing unit 22120 is provided as an image
processing board (not shown) in which a circuit system including
various chip sets (not shown), a memory (not shown), electronic
components (not shown) and wiring (not shown) to conduct such
processes is mounted on a printed circuit board (PCB, not
shown).
[0276] The display unit 22160 displays an image based on an image
signal output from the image processing unit 22120. The display
unit 22160 may be configured in various display modes using liquid
crystals, plasma, light emitting diodes, organic light emitting
diodes, a surface conduction electron emitter, a carbon nano-tube,
nano-crystals, or the like, without being limited thereto.
[0277] The display unit 22160 may further include an additional
element depending on a display mode thereof. For example, in a
display mode using liquid crystals, the display unit 22160 may
include a liquid crystal display (LCD) panel, a backlight unit (not
shown) providing light to the panel, and a panel drive board (not
shown) driving the panel.
[0278] The user input unit 22170 transmits various preset control
commands or unlimited information to the controller 22110 by a
user's manipulation and input. The user input unit 22170 may be
provided as a menu key and an input panel installed on an outside
of the display apparatus 22100 or as a remote controller separate
from the display apparatus 22100.
[0279] Alternatively, the user input unit 22170 may be configured
as a single body with the display unit 22160. That is, if the
display unit 22160 is a touch screen, a user may transmit a preset
command to the controller 22110 through an input menu (not shown)
displayed on the display unit 22160.
[0280] The storage unit 22150 may store unlimited data according to
control of the controller 22110. The storage unit 22150 may be
configured as a non-volatile memory, such as a flash memory and a
hard disk drive. The storage unit 22150 is accessible by the
controller 22110, and the data stored in the storage unit 22150 may
be read, recorded, revised, deleted, or updated by the controller
22110.
[0281] The storage unit 22150 may store, for example, an operating
system to run the display apparatus 22100 and various applications,
image data, and optional data which are executable in the operating
system.
[0282] Further, the storage unit 22150 may store information on a
control of the controller 22110 on an operation of the upgrade
apparatus 22200 when the upgrade apparatus 22200 is connected.
[0283] The connection unit 22130 may be configured as a connection
port in accordance with HDMI, USB or component standards or LVDS
standard for communication with the upgrade apparatus 22200.
[0284] The connection unit 22130 may be provided in any type and
form, without being limited to the foregoing examples, as long as
it is configured to enable the display apparatus 22100 and the
upgrade apparatus 22200 to communicate at least one of data, a
signal, information, and power with each other.
[0285] Further, the connection unit 22130 may include a plurality
of terminals to be connected to a plurality of upgrade apparatuses
22200 having different upgraded functions.
[0286] The controller 22110 performs control operations over
various components of the display apparatus 22100. For example, the
controller 22110 conducts image processing in charge of the image
processing unit 22120, transmission/reception operations of
signals, information, or data through the connection unit 22130,
and a control operation corresponding to a command from the user
input unit 22170, thereby controlling the general operations of the
display apparatus 22100.
[0287] Further, the controller 22110 may include a microcomputer
(not shown) to adjust a control range of the controller 22100
corresponding to an operation of the upgrade apparatus 22200 when
the upgrade apparatus 22200 is connected to the connection unit
22130.
[0288] That is, the microcomputer may communicate with the upgrade
apparatus 22200 and assign the control to the upgrade apparatus
22200 or allow the controller 22110 to hold the control with
respect to each operation based on the information stored in the
storage unit 22150.
[0289] Accordingly, the controller 22110 may control a received
image signal to be processed by the upgrade apparatus 22200 when
the upgrade apparatus 22200 is connected to the connection unit
22130.
[0290] Furthermore, the controller 22110 may control the image
processing unit 22120 to conduct first image processing on a
received image signal and enable the upgrade apparatus 22200 to
conduct second image processing on a processed first image.
[0291] In addition, the controller 22110 may control the image
processing unit 22120 to receive a second image processed by the
upgrade apparatus 22200 and to conduct third image processing on
the second image.
[0292] Also, the controller 22110 may control the display unit
22160 to receive an image signal processed by the upgrade apparatus
22200 and to display the received image signal.
[0293] Moreover, the controller 22110 may control the display unit
22160 to receive an image signal processed by the upgrade apparatus
22200 and to display the received image signal via follow-up image
processing processes by the image processing unit 22120.
[0294] Further, the controller 22110 may assign the control to the
upgrade apparatus 22200 so that the image processing unit 22120
processes a received image signal according to control of the
upgrade apparatus 22200.
[0295] In addition, the controller 22110 may control the display
unit 22160 to receive an image signal received and processed by the
upgrade apparatus 22200 and to display an image based on the
received image signal.
[0296] Upgrading the display apparatus 22100 having the foregoing
configuration is necessary for various cases, for example, to
receive an image signal in a new format which is not proposed when
the display apparatus 22100 is first manufactured, to receive an
image signal with a higher level than supported solely by the
display apparatus 22100, or to reduce system load of the display
apparatus 22100.
[0297] Upgrading the display apparatus 22100 may be carried out in
terms of hardware and software. In the present exemplary
embodiment, the upgrade apparatus 22200 provided to upgrade the
display apparatus 22100 is connected to the connection unit 22130,
thereby upgrading at least one of the existing hardware and
software configurations of the display apparatus 22100.
[0298] The upgrade apparatus 22200 includes hardware or software
configurations corresponding to at least part of the hardware or
software resources of the display apparatus 22100. These hardware
or software configurations of the upgrade apparatus 22200 are
provided to perform more improved functions than the at least part
of the resources of the display apparatus 22100. Thus, when the
upgrade apparatus 22200 is connected to the display apparatus
22100, the display apparatus 22100 may provide an image with more
improved quality than that solely realized by the display apparatus
22100.
[0299] Hereinafter, the configuration of the upgrade apparatus
22200 will be described.
[0300] The upgrade apparatus 22200 includes a connection unit 22230
connected to the connection unit 22130 of the display apparatus
22100, an image processing unit 22220 capable of replacing an image
processing process of the image processing unit 22120 or performing
processes corresponding to at least part of the image processing
processes of the image processing unit 22120, a storage unit 22250
storing unlimited data or information, a signal input/output unit
22240 inputting/outputting an image signal, and a controller 22210
controlling general operations of the upgrade apparatus 22200.
[0301] The connection unit 22230 is connected to the connection
unit 22130, thereby enabling communication between the upgrade
apparatus 22200 and the display apparatus 22100. The connection
unit 22230 may be connected to the connection unit 22130 via wire
or wirelessly. The connection unit 22230 may be connected to the
connection unit 22130 in various methods, without being
particularly limited.
[0302] The image processing unit 22220 may perform image processing
instead of the image processing unit 22120 of the display apparatus
22100 or perform part of all image processing processes performed
by the image processing unit 22120 instead. The image processing
processes performed by the image processing unit 22220 instead of
the image processing unit 22120 include a function upgraded from a
function of the image processing unit 22120 of the display
apparatus 22100 or an additional function which the image
processing unit 22120 is not capable of performing and are achieved
by upgrading hardware, such as a chip set, or software, such as
algorithms, executable codes, or programs.
[0303] For example, the image processing unit 22220 processes an
image signal with high resolution or an image signal in a format
which the image processing unit 22120 cannot handle.
[0304] The storage unit 22250 stores unlimited data. The storage
unit 22250 is configured as a nonvolatile memory, such as a flash
memory and a hard disk drive. The storage unit 22250 is accessed by
the controller 22110 of the display apparatus 22100 or the
controller 22210, and the data stored in the storage unit 22250 is
read, recorded, revised, deleted, or updated by controller 22110 or
controller 22210. Meanwhile, the storage unit 22150 may also be
accessed by not only the controller 22110 but the controller 22210
depending on a configuration thereof.
[0305] Further, when an operating system stored in the storage unit
22250 is a more upgraded version than the operating system stored
in the storage unit 22150, the operating system of the storage unit
22150 may be updated to the operating system of the storage unit
22250 to run the updated operating system, or the operating system
of the storage unit 22250 may be run instead of the operating
system of the storage unit 22150.
[0306] Further, the storage unit 22250 stores information
corresponding to the information associated with assigning control
priority stored in the storage unit 22150 of the display apparatus
22100. Accordingly, the control priority between the controller
22110 and controller 22210 may be adjusted using communication with
the display apparatus 22100.
[0307] The signal input/output unit 22240 transmits a received
image signal to the image processing unit 22220 and is configured
in various types in accordance with standards of received signals
and formats of the image source and the display apparatus 22100.
For example, the signal input/output unit 22240 may receive signals
or data in accordance with HDMI, USB, and component standards and
include a plurality of connection terminals (not shown)
corresponding to the respective standards.
[0308] Further, the signal input/output unit 22240 may include an
input unit for an image signal in a new format which the signal
input/output unit 22140 of the display apparatus 22100 cannot
receive.
[0309] The controller 22210 controls a connection operation of the
display apparatus 22100 and the upgrade apparatus 22200 for
performing the general image processing processes.
[0310] Further, the controller 22210 may include a microcomputer
(not shown) to communicate with the controller 22110 of the display
apparatus 22100 when the display apparatus 22100 is connected to
the connection unit 22230.
[0311] The controller 22210 and the controller 22110 may be
configured as a CPU. Thus, if the controller 22210 performs a more
improved function than the controller 22110, the controller 22210
may disable the controller 22110 and control general operations of
the display system 221 instead of the controller 22110.
Alternatively, the controller 22210 may control the general
operations of the display system 221 together with the controller
22110.
[0312] Further, the controller 22210 communicates with the display
apparatus 22100 and may be assigned a control with respect to each
operation based on the information stored in the storage unit
22250.
[0313] Accordingly, the controller 22210 may control an image
signal to be processed by the image processing unit 22220.
[0314] In addition, the controller 22210 may control the processed
image signal to be transmitted to the display apparatus 22100 and
displayed on the display unit 22160.
[0315] Hereinafter, a control method of the display apparatus 22100
according to an exemplary embodiment will be described with
reference to FIG. 22.
[0316] As shown in FIG. 22, the controller 22110 detects whether
the upgrade apparatus 22200 is connected to the display apparatus
22100 through the connection unit 22130 of the display apparatus
22100 (S22100).
[0317] When the upgrade apparatus 22200 is not connected to the
display apparatus 22100, the controller 22110 controls all
operations of the display apparatus 22100 according to a preset
process.
[0318] When the upgrade apparatus 22200 is connected to the display
apparatus 22100, the controller 22110 determines at least one
function of the display apparatus 22100 to be upgraded
corresponding to the upgrade apparatus 22200 (S22110).
[0319] For example, among image processing processes, such as
demultiplexing to separate a signal into an image signal, an audio
signal and optional data, decoding the demultiplexed image signal
into an image format, and scaling the decoded image signal to a
preset resolution, a decoding process is determined
[0320] The controller 22110 controls the upgraded function to be
performed using the upgrade apparatus 22200 (S22120).
[0321] For example, the controller 22110 controls the determined
decoding process to be conducted by the image processing unit 22220
of the upgrade apparatus 22200.
[0322] Further, the controller 22110 may control the display unit
22160 to receive and display an image signal processed by the
upgrade apparatus 22200.
[0323] In addition, the controller 22110 may determine all
functions with respect to the image processing processes and assign
a control to the upgrade apparatus 22200, so that a received image
signal may be processed overall by the upgrade apparatus 22200.
[0324] Hereinafter, a control method of the upgrade apparatus 22200
according to an exemplary embodiment will be described with
reference to FIG. 23.
[0325] As shown in FIG. 23, the controller 22210 detects whether
the display apparatus 22100 is connected to the upgrade apparatus
22200 through the connection unit 22230 (S22200).
[0326] When the display apparatus 22100 is connected, the
controller 22210 notifies the display apparatus 22100 of at least
one upgraded function to be provided to the display apparatus 22100
(S22210).
[0327] The controller 22210 controls the at least one upgraded
function to be conducted (S22220).
[0328] Here, the controller 22210 may be assigned a control from
the controller 22110 of the display apparatus 22100 in order to
conduct the upgraded function.
[0329] For example, the controller 22210 may control the received
image signal to be partly or entirely processed by the image
processing unit 22220.
[0330] Then, the controller 22210 may transmit the processed image
signal by the image processing unit 22220 to the display apparatus
so that an image based on the image signal is displayed on the
display unit 22160.
[0331] Hereinafter, control operations of the controller 22110 and
the controller 22210 when the display apparatus 22100 and the
upgrade apparatus 22200 are connected according to exemplary
embodiments will be described with reference to FIG. 24.
[0332] FIG. 24(a) illustrates the controller 22210 of the upgrade
apparatus 22200 is assigned a control from the display apparatus
22100 to conduct general control.
[0333] For example, when the display apparatus 22100 and the
upgrade apparatus 22200 are connected, the controller 22210 is
assigned a control over all received image signals to be processed
by the image processing unit 22220 of the upgrade apparatus 22200
and may disable the controller 22110 and/or the image processing
unit 22120 of the display apparatus 22100.
[0334] FIG. 24(b) illustrates the controller 22110 of the display
apparatus 22100 and the controller 22210 of the upgrade apparatus
22200 performing control in combination.
[0335] For example, the controller 22110 may control the image
processing unit 22120 to conduct first image processing on a
received image signal, and the controller 22210 of the upgrade
apparatus 22200 may receive the first-processed image signal and
control the image processing unit 22220 to conduct second image
processing on the image signal.
[0336] FIG. 24(c) illustrates the controller 22110 of the display
apparatus 22100 performs main control and the controller 22210 of
the upgrade apparatus 22200 performs sub-control.
[0337] For example, the controller 22110 of the display apparatus
22100 may control a received video signal to be processed by the
image processing unit 22120 and to be displayed on the display unit
22160, and the controller 22210 of the upgrade apparatus 22200 may
control the image processing unit 22220 to process a graphic image,
such as a GUI, overlapping the video image displayed on the display
apparatus 22100.
[0338] Alternatively, the controller 22210 of the upgrade apparatus
22200 may perform control depending on an instruction of the
controller 22110 of the display apparatus 22100.
[0339] FIG. 24(d) illustrates the controller 22210 of the upgrade
apparatus 22200 performs main control and the controller 22110 of
the display apparatus 22100 performs sub-control, which is, for
example, the reverse of FIG. 24(c).
[0340] Hereinafter, an image processing apparatus (display
apparatus), an upgrade apparatus, and a display system according to

kinds or standards of image signals and configurations of the
display apparatus 44100.
[0391] The first image processing unit 44130 performs various
preset image processing processes on an image signal received by
the image reception unit 44120. The image processing processes
include, for example, conversion of an analog image signal to a
digital image signal, demodulating to shift a frequency of an image
signal to a baseband, decoding in accordance with image and audio
formats, de-interlacing to convert an interlaced image signal into
a progressive form, scaling to adjust an image signal to a preset
resolution, and various types of color processing to adjust color

When the upgrade apparatus 44200 is connected, the controller 44150
checks which image processing process the second image processing
unit 44210 of the upgrade apparatus 44200 can perform. As described
above, the first image processing unit 44130 includes the plurality
of first blocks, and the controller 44150 identifies whether the
second image processing unit 44210 includes second blocks
corresponding to the respective first blocks, thereby identifying
whether the second image processing unit 44210 of the upgrade
apparatus 44200 is able to perform an image processing process
carried out by a particular first block.
[0398] When it is determined that the second image processing unit
44210 includes a second block corresponding to the particular first

thereof may be included.
[0405] An image signal received by the image reception unit 44120
is input to a first demultiplexer 44161 via A/D conversion. The
controller 44150 controls the input image signal to be output
either to the first definition enhancement block 44131 or to the
second definition enhancement block 44211 based on a presetting or
a user selection, and the block which receives the output signal
performs an image processing process for definition
enhancement.
[0406] After definition enhancement processing, the image signal is
output to a second demultiplexer 44163, and then output to the
first color selection block 44133 or the second color selection
block 44213 according to control of the controller 44150.
[0407] After a plurality of image processing processes, the image
signal is finally output to the display unit 44110. As described
above, FIG. 31 illustrates part of the image processing processes
only, and it is obvious that the image signal received from the
image reception unit 44120 may need to go through a series of image
processing processes other than those shown in FIG. 31 to be
finally displayed on the display unit 44110.
[0408] According to the display apparatus 44100, at least part of
the image processing processes is performed by the external upgrade
apparatus 44200 connected to the display apparatus 44100, thereby
carrying out enhanced image processing processes without
replacement of hardware of the display apparatus 44100.
[0409] FIG. 32 is a flowchart illustrating a control method of the
display apparatus 44100 according to an exemplary embodiment.
[0410] The display apparatus 44100 may be configured as any types
capable of displaying an image including a TV and can be connected
to the upgrade apparatus 44200 to exchange data.
[0411] The display apparatus 44100 receives an analog or digital
image signal from an external image source (not shown)
(S44110).
[0412] The display apparatus 44100 identifies whether the upgrade
apparatus 44200 is connected to the display apparatus 44100
(S44120). The connection unit 44140 connected to the upgrade
apparatus 44200 is connected to the ground terminal. Thus, when the
upgrade apparatus 44200 is connected, an electrical signal by
ground connection is detected, thereby identifying whether the
upgrade apparatus 44200 is connected.
[0413] The display apparatus 44100 may include a plurality of first
blocks performing a plurality of image processing processes,
respectively, and the upgrade apparatus 44200 may include a
plurality of second blocks respectively corresponding to the first
blocks and performing part of the image processing processes. The
received image signal is processed according to a predetermined
image processing process, and the respective second blocks may
perform functions corresponding to the image processing processes
conducted by the first blocks.
[0414] When the upgrade apparatus 44200 is not connected, all image
processing processes are conducted by the display apparatus 44100
(S44160).
[0415] When the upgrade apparatus 44200 is connected, the display
apparatus 44100 identifies an image processing process that the
upgrade apparatus 44200 is able to perform (S44130). Here, the
display apparatus 44100 checks whether the upgrade apparatus 44200
includes second blocks corresponding to the respective first
blocks, thereby identifying an image processing process that the
upgrade apparatus 44200 is able to perform.
[0416] When the upgrade apparatus 44200 is capable of performing a
particular image processing process, an apparatus to perform the
process is selected among the display apparatus 44100 and the
upgrade apparatus 44200 (S44140). That is, any one of a first block
and a corresponding second block is selected. In this case, the
display apparatus 44100 may include a plurality of switching units
respectively connected to the first blocks and the second blocks
respectively corresponding to the first blocks to transmit a signal
to either of the first blocks and the second blocks, which has been
described above with reference to FIG. 31.
[0417] According to a selection result, any one of the display
apparatus 44100 and the upgrade apparatus 44200 performs the image
processing process (S44150). In this case, regarding selection of
an apparatus, all second blocks may be used based on a presetting
of the upgrade apparatus 44200, or any one of the first blocks and
the corresponding second blocks may be selected based on a user
selection.
[0418] According to the control method of the display apparatus
44100, at least part of the image processing processes is carried
out by the external upgrade apparatus 44200 connected to the
display apparatus 44100, thereby carrying out enhanced image
processing processes without replacement of hardware of the display
apparatus 44100.
[0419] Hereinafter, an image processing apparatus (display
apparatus), an upgrade apparatus, and a display system according to
another exemplary embodiment will be described. In the present
exemplary embodiment, descriptions of components which are the same
as or similar to those of the image processing apparatuses 100 to
100g, the display apparatuses 22100, 33100 and 44100, the upgrade
apparatuses 200 to 200g, 22200, 33200 and 44200, and the display
systems 1 to 1g, 221 and 331 described with reference to FIGS. 1 to
32 will be omitted herein.
[0420] FIG. 33 is a block diagram illustrating a configuration of a
display system 551 according to an exemplary embodiment. As shown
in FIG. 33, the display system 551 includes a display apparatus
55100 and a three-dimensional (3D) image processing apparatus
55200. The display apparatus 55100 and the 3D image processing
apparatus 55200 are connected to communicate with each other.
[0421] The display apparatus 55100 and the 3D image processing
apparatus 55200, which are connected to each other, transmit and
receive an image signal, such as a broadcast signal, and a control
signal including various types of data and power.
[0422] The display apparatus 55100 processes an image signal
provided from an external image source (not shown) according to a
preset image processing process to display an image. Here, the
display apparatus 55100 processes a two-dimensional (2D) image
signal to display a 2D image.
[0423] In the display system 551 according to the present exemplary
embodiment, the display apparatus 55100 is configured as a TV which
displays a broadcast image based on a broadcast signal, broadcast
information, or broadcast data received from a transmitter of a
broadcasting station. However, the display apparatus 55100 may be
configured as any type of device which is capable of displaying an
image, without being limited to a TV.
[0424] Further, the display apparatus 55100 may display any type of
image, without being limited to a broadcast image. For example, the
display apparatus 55100 may display images, such as videos, still
images, applications, on-screen display (OSD) based on signals or
data received from various types of image sources (not shown), and
GUIs for controlling various operations.
[0425] The 3D image processing apparatus 55200 is connected to the
display apparatus 55100 to communicate therewith. The 3D image
processing apparatus 55200 upgrades existing hardware or software
of the connected display apparatus 55100 for 3D display and enables
an image signal to be processed by the upgraded hardware or
software of the display apparatus 55100, thereby displaying a 3D
image.
[0426] For example, the 3D image processing apparatus 55200 may be
a device to upgrade hardware of a TV, such as an image processing
circuit, for 3D display and be detachable from the display
apparatus 55100.
[0427] Meanwhile, unlike in the present exemplary embodiment, the
3D image processing apparatus 55200 may be connected to the display
apparatus 55100 wirelessly. In this case, the 3D image processing
apparatus 55200 may be supplied with operation power from a
separate external power source or battery. However, the present
exemplary embodiment will be described with reference to the 3D
image processing apparatus 55200 connected to the display apparatus
55100 via wire.
[0428] The display apparatus 55100 may solely process an image
signal received from the outside according to a preset image
processing process to display an image.
[0429] According to the present exemplary embodiment, as the 3D
image processing apparatus 55200 is connected to the display
apparatus 55100, hardware or software configurations of the display
system 551 performing the above image processing process are
upgraded. The 3D image processing apparatus 55200 receives an image
signal from the display apparatus 55100, processes the image signal
into a 3D image signal, and transmits the processed image signal to
the display apparatus 55100. The display apparatus 55100 displays a
3D image corresponding to the 3D image signal received from the 3D
image processing apparatus 55200.
[0430] In another exemplary embodiment, the 3D image processing
apparatus 55200 may receive an image signal, processes the image
signal into a 3D image signal, and transmits the processed image
signal to the display apparatus 55100. The display apparatus 55100
displays a 3D image corresponding to the 3D image signal received
from the 3D image processing apparatus 55200.
[0431] Accordingly, the display apparatus 55100 supporting 2D
display may also provide a 3D image to a user.
[0432] FIG. 34 is a block diagram illustrating a configuration of
the display apparatus 55100 of the display system 551 according to
an exemplary embodiment.
[0433] As shown in FIG. 34, the display apparatus 55100 includes a
first image reception unit 55110 to which at least one image source
55300 is connected, a first image processing unit 55120 processing
an image signal received from the image source 55300 through the
first image reception unit 55110, a display unit 55130 displaying
an image based on the image signal processed by the first image
processing unit 55120, a first connection unit 55140 to which the
3D image processing apparatus 55200 is detachably connected, a user
input unit 55150 outputting a preset command based on user input, a
first storage unit 55160 storing unlimited data or information, and
a first controller 55170 controlling operations of all components
of the display apparatus 55100.
[0434] The first image reception unit 55110 is an input/output
(I/O) device transmitting an image signal received from the at
least one image source 55300 to the first image processing unit
55120 and is configured as various types corresponding to standards
of received image signals or configurations of the image source
55300 and the display apparatus 55100. For example, the first image
reception unit 55110 may receive signals or data in accordance with
the HDMI, USB, and component standards and may include a plurality
of connection terminals (not shown) corresponding to the respective
standards. Various external devices including the image source
55300 are connected to the respective connection terminals, thereby
enabling communication via the first image reception unit 55110.
The image signals received through the first image reception unit
55110 include a 2D image signal and a 3D image signal.
[0435] The first image processing unit 55120 may perform various
preset image processing processes on an image signal received from
the first image reception unit 55110. The first image processing
unit 55120 outputs a processed image signal to the display unit
55130, so that an image based on the image signal is displayed on
the display unit 55130.
[0436] The first image processing unit 55120 may perform any type
of image processing, without being limited to, for example,
demultiplexing to separate a signal into characteristic signals,
decoding in accordance with an image format of an image signal,
de-interlacing to convert an interlaced image signal into a
progressive form, scaling to adjust an image signal to a preset
resolution, noise reduction to improve image quality, detail
enhancement, frame refresh rate conversion, or the like.
[0437] The first image processing unit 55120 is provided as an
image processing board 55125, as shown in FIG. 36, in which a
circuit system including various chip sets (not shown), a memory
(not shown), electronic components (not shown) and wiring (not
shown) to conduct such processes is mounted on a printed circuit
board (PCB, not shown).
[0438] The display unit 55130 displays an image based on an image
signal output from the first image processing unit 55120. The
display unit may be configured in various display modes using
liquid crystals, plasma, light emitting diodes, organic light
emitting diodes, a surface conduction electron emitter, a carbon
nano-tube, nano-crystals, or the like, without being limited
thereto.
[0439] As shown in FIG. 38, the display unit 55130 may further
include an additional element depending on a display mode thereof.
For example, in a display mode using liquid crystals, the display
unit 55130 may include an LCD panel 55131, a backlight unit (not
shown) providing light to the panel 55131, a panel drive board (not
shown) including a driver to drive the panel 55131, and a timing
controller (T-con) 55135 coupled to a front end portion of the
display panel 55131 to control the driver and improve image
quality.
[0440] The 3D image processing apparatus 55200 is detachably
coupled to the first connection unit 55140. The display apparatus
55100 and the 3D image processing apparatus 55200 are coupled to
each other by various methods, which will be described in
detail.
[0441] The first connection unit 55140 communicates with the 3D
image processing apparatus 55200. In detail, the first connection
unit 55140 transmits an image signal received from the image source
55300 to the 3D image processing apparatus 55200 and receives a
processed 3D image signal from the 3D image processing apparatus
55200.
[0442] The user input unit 55150 transmits various preset control
commands or unlimited information to the first controller 55170 by
a user's manipulation and input. The user input unit 55150 may be
provided as a menu key and an input panel installed on an outside
of the display apparatus 55100 or as a remote controller separate
from the display apparatus 55100.
[0443] Alternatively, the user input unit 55150 may be configured
as a single body with the display unit 55130. That is, if the
display unit 55130 is a touch screen, a user may transmit a preset
command to the first controller 55170 through an input menu (not
shown) displayed on the display unit 55130.
[0444] The first storage unit 55160 may store unlimited data
according to control of the first controller 55170. The first
storage unit 55160 may be configured as a non-volatile memory, such
as a flash memory and a hard disk drive. The first storage unit
55160 is accessible by the first controller 55170, and the data
stored in the first storage unit 55160 may be read, recorded,
revised, deleted, or updated by the first controller 55170.
[0445] The first storage unit 55160 may store, for example, an
operating system to run the display apparatus 55100 and various
applications, image data, and optional data which are executable in
the operating system.
[0446] The first controller 55170 performs control operations over
various components of the display apparatus 55100. For example, the
first controller 55170 conducts image processing by the first image
processing unit 55120, transmission or reception operations of
signals, information, or data through the first connection unit
55110, and a control operation corresponding to a command from the
user input unit 55150, thereby controlling the overall operation of
the display apparatus 55100.
[0447] When the 3D image processing apparatus 55200 is connected,
the first controller 55170 may identify that an image signal
received through the first image reception unit 55110 is a 3D image
signal through upgrade of firmware of the first image processing
unit 55120. The first controller 55170 transmits the identified 3D
image signal to the 3D image processing apparatus 55200, controls
the first connection unit 55140 to receive the processed 3D image
signal from the 3D image processing apparatus 55200, and controls
the display unit 55130 to display a 3D image based on the processed
3D image signal.
[0448] The display apparatus 55100 having the foregoing
configuration needs upgrading over time due to various factors,
such as technology development. Upgrading is necessary, for
example, to receive a 3D image signal which is not proposed when
the display apparatus 55100 is first manufactured. According to the
present exemplary embodiment, the 3D image processing apparatus
55200 provided to upgrade the display apparatus 55100 is connected
to the first connection unit 55140, thereby upgrading the display
apparatus 55100 to achieve 3D display.
[0449] The 3D image processing apparatus 55200 includes hardware or
software configurations corresponding to at least part of the
hardware or software resources of the display apparatus 55100.
These hardware or software configurations of the 3D image
processing apparatus 55200 are provided to perform more improved
functions than at least part of the resources of the display
apparatus 55100. Thus, when the 3D image processing apparatus 55200
is connected to the display apparatus 55100, the hardware or
software configurations of the 3D image processing apparatus 55200
replace at least part of the resources of the display apparatus
55100, thereby finally displaying a 3D image on the display
apparatus 55100.
[0450] FIG. 35 is a block diagram illustrating a configuration of
the 3D image processing apparatus 55200 of the display system 551
according to an exemplary embodiment.
[0451] The 3D image processing apparatus 55200 includes a second
image reception unit 55210 to which at least one image source 55300
is connected, a second image processing unit 55220 processing a 3D
image signal, a second connection unit 55240 connected to the first
connection unit 55140 of the display apparatus 55100, a second
storage unit 55260 storing unlimited data/information, a second
controller 55270 controlling general operations of the 3D image
processing apparatus 55200, and a communication unit 55280
communicating with a pair of 3D glasses 55281.
[0452] The second image reception unit 55210 receives an image
signal from the at least one image source 55300 and can be
configured as various types corresponding to standards of received
image signals or configurations of the image source 55300 and the
display apparatus 55100. For example, the second image reception
unit 55210 may receive signals or data in accordance with the HDMI,
USB, and component standards and may include a plurality of
connection terminals (not shown) corresponding to the respective
standards. Various external devices including the image source
55300 are connected to the respective connection terminals, thereby
enabling communication via the second image reception unit 55210.
The image signals received through the second image reception unit
55210 include a 2D image signal and a 3D image signal.
[0453] Although FIG. 35 illustrates the 3D image processing
apparatus 55200 including the second image reception unit 55210 to
receive an image signal, in another exemplary embodiment a
component to receive an image signal in the 3D image processing
apparatus 55200 may not be provided. When the second image
reception unit 55210 is not provided, the 3D image processing
apparatus 55200 receives an image signal from the display apparatus
55100, processes the received image signal, and transmits the
processed image signal to the display apparatus 55100.
[0454] A 3D image may include a left-eye image and a right-eye
image which are alternately displayed. A broadcast signal may be
received in a form of a data stream. A stream of a broadcast signal
includes, for example, an MPEG2 transport stream. The broadcast
signal may include two or more streams. For example, the broadcast
signal may include two streams (hereinafter, also referred to as a
first stream and a second stream) respectively corresponding to a
left-eye image and a right-eye image of a 3D image.
[0455] The second image processing unit 55220 processes a 3D image
signal. The second image processing unit 55220 conducts
demultiplexing, decoding, transcoding, scaling, or the like. The
second image processing unit 55220 may include a demultiplexer (not
shown), a first decoder (not shown) and a second decoder (not
shown). When a broadcast signal is demultiplexed to first and
second streams respectively corresponding to a left-eye image and a
right-eye image of a 3D image, the demultiplexer separates the
broadcast signal into the first stream and the second stream. The
first decoder decodes the first stream to output the left-eye
image, and the second decoder decodes the second stream to output
the right-eye image. The decoded left-eye and right-eye images are
alternately displayed by the display unit 55130 of the display
apparatus 55100.
[0456] The second image processing unit 55220 may further include a
dimming block (not shown) for turning on/off a power supply of a
backlight to improve quality of a 3D image. The dimming block
enables 3D contents to be more effectively reproduced.
[0457] The second image processing unit 55220 may include a 3D
formatter converting a 2D image signal into a 3D image signal. The
2D image signal includes a plurality of image frames (hereinafter,
referred to as "frames"). The 3D image signal, which uses binocular
disparity, may include a plurality of left-eye frames and a
plurality of right-eye frames. Among the left-eye frames and the
right-eye frames, a pair including a left-eye frame and a right-eye
frame may be converted from at least one corresponding frame among
the plurality of frames of the 2D image signal.
[0458] When the display apparatus 55100 and the 3D image processing
apparatus 55200 are connected, the second image processing unit
55220 processes a 3D image signal or converts a 2D image signal
into a 3D image signal according to control of the first controller
55170 or the second controller 55270, thereby reproducing a 3D
image, which will be described in detail.
[0459] The second connection unit 55240 is detachably connected to
the first connection unit 55140, thereby enabling communication
between the 3D image processing apparatus 55200 and the display
apparatus 55100.
[0460] FIGS. 36 to 38 illustrate the 3D image processing apparatus
55200 which is connected to the display apparatus 55100.
[0461] The 3D image processing apparatus 55200 may be detachably
connected to any one of the timing controller 55135, the display
panel 55131, and the image processing board 55125 of the display
apparatus 55100.
[0462] As shown in FIG. 36, the second connection unit 55210 may be
connected to at least one connector 551412 among a plurality of
connectors 55141 and 55142 provided in the timing controller 55135.
Here, the display apparatus 55100 is launched with the image
processing board 55125 connected to connector 55141. Connector
55142 is a spare connector. The 3D image processing apparatus 55200
will be connected to the spare connector 55142, thereby upgrading
the display apparatus 55100 to achieve 3D display.
[0463] When the display apparatus 55100 does not include the spare
connector 55142 for connection of the 3D image processing apparatus
55200, the 3D image processing apparatus 55200 may be coupled
through a gender changer 55143 connected to the first connection
unit 55140, as shown in FIG. 37.
[0464] Meanwhile, as shown in FIG. 38, the display apparatus 55100
may be launched with the timing controller 55135 slidingly coupled
to slots of the display panel 55131 and the image processing board
55125. Then, a module, which is designed in a combined form of the
3D image processing apparatus 55200 and the timing controller
55135, replaces the timing controller 55135, thereby conveniently
upgrading the display apparatus 55100 to enable 3D image
processing.
[0465] Connection methods of the 3D image processing apparatus
55200 shown in FIGS. 36 to 38 are provided only for illustrative
purposes, and the first connection unit 55140, and the second
connection unit 55240 may be connected by various methods in
addition to the foregoing examples.
[0466] The second storage unit 55260 stores unlimited data. The
second storage unit 55260 is configured as a non-volatile storage
medium, such as a flash memory and a hard disk drive. The second
storage unit 55260 is accessed by the first controller 55170 or the
second controller 55270, and the data stored in the second storage
unit 55260 may be read, recorded, revised, deleted, or updated by
the controller 55170 and the controller 55270. Meanwhile, the
second storage unit 55260 may be also accessed not only by the
second controller 55270 but by the first controller 55170 based on
a configuration thereof.
[0467] The second controller 55270 performs control operations over
various components of the 3D image processing apparatus 55200 to
conduct general image processing processes. For example, the second
controller 55270 conducts image processing by the second image
processing unit 55220 and transmission or reception operations of
signals, information, or data through the second connection unit
55210, thereby controlling general operations of the 3D image
processing apparatus 55200.
[0468] The second controller 55270 and the first controller 55170
may be configured as a CPU. Thus, when a 3D image signal is
received, the second controller 55270 may disable the first
controller 55170 and control general operations of the display
system 551 instead of the first controller 55170. Alternatively,
the second controller 55270 may control the general operations of
the display system 551 together with the first controller
55170.
[0469] The second controller 55270 and the first controller 55170
may further include a graphic processing unit (GPU) subserving the
CPU, a digital signal processor (DSP), and a memory, such as a DDR
RAM.
[0470] The communication unit 55280 communicates with the pair of
3D glasses 55281 and synchronizes a signal transmitted to the 3D
glasses 55281 with a processed 3D image signal. The 3D glasses
55281 is configured as a pair of shutter glasses selectively
transmitting light depending on an application of voltage or a pair
of polarized glasses transmitting light in a preset polarization
direction.
[0471] The communication unit 55280 may include a wireless
communication module in accordance with a predetermined
communication standard, such as radio frequency (RF), Zigbee,
Bluetooth, near field communication (NFC), and infrared
communication, and may enable transmission and reception of various
unlimited signals, information, or data between the display
apparatus 55100 and the 3D glasses 55281.
[0472] Hereinafter, a process of upgrading the display apparatus
55100 to achieve 3D display by the 3D image processing apparatus
55200 according to an exemplary embodiment will be described with
reference to FIGS. 39 to 43.
[0473] FIGS. 39 to 43 are flowcharts illustrating methods of
performing an image processing process of the display apparatus
55100 ungraded by the 3D image processing apparatus 55200 in the
display system 551 according to exemplary embodiments.
[0474] When a 2D or 3D image signal is received from the image
source 55300 in operation S55411 of FIG. 39, the display apparatus
55100 processes the image signal according to a preset sequence of
image processing processes in operations S55413, S55415, and S55417
of FIG. 39. It should be noted that FIG. 39 illustrates only some
image processing processes for concise description of the present
exemplary embodiment, and does not show all image processing
processes actually implemented by the display apparatus 55100.
[0475] FIGS. 39 and 40 illustrate an image signal received through
the first image reception unit 55110 of the display apparatus
55100.
[0476] As shown in FIG. 39, when the display apparatus 55100
receives a 3D image signal from the image source 55300 in operation
S55411, the first controller 55170 identifies the received signal
as a 3D image signal in operation S55413 and transmits the signal
to the 3D image processing apparatus 55200 in operation S55414. The
second controller 55270 controls the second image processing unit
55220 to process the received 3D image signal in operation S55415
and transmits the processed 3D image signal to the display
apparatus 55100 in operation S55416. The first controller 55170
displays a 3D image based on the 3D image signal on the display
unit 55130 in operation S55417.
[0477] As shown in FIG. 40, when the display apparatus 55100
receives a 2D image signal from the image source 55300 in operation
S55421, the first controller 55170 identifies the received image
signal as a 2D image signal in operation S55423 and controls the
first image processing unit 55120 to process the 2D image signal in
operation S55425. The first controller 55170 transmits the
processed 2D image signal to the 3D image processing apparatus
55200 in operation S55426. The second controller 55270 controls the
second image processing unit 55220 to convert the received 2D image
signal into a 3D image signal in operation S55427 and transmits the
converted 3D image signal to the display apparatus 55130 in
operation S55428. The first controller 55170 displays a 3D image
based on the 3D image signal on the display unit 55130 in operation
S55429.
[0478] Although FIG. 40 illustrates that the first image processing
unit 55120 processes a 2D image signal and the second image
processing unit 55220 converts the 2D image signal into a 3D image
signal, the second image processing unit 55220 may process a 2D
image signal and convert the 2D image signal into a 3D image
signal. In this case, the first controller 55170 may identify an
image signal as a 2D signal and transmit the signal to the 3D image
processing apparatus 55200.
[0479] FIGS. 41 to 43 illustrate the 3D image processing apparatus
55200 including the second image reception unit 55210 to receive an
image signal autonomously.
[0480] As shown in FIG. 41, when the 3D image processing apparatus
55200 receives a 3D image signal from the image source 55300 in
operation S55431, the second controller 55270 identifies the
received image signal as a 3D image signal in operation S55433 and
controls the second image processing unit 55120 to process the
received 3D image signal in operation S55435. The second controller
55270 transmits the processed 3D image signal to the display
apparatus 55100 in operation S55436. The first controller 55170
displays a 3D image based on the 3D image signal on the display
unit 55130 in operation S55437.
[0481] As shown in FIG. 42, when the 3D image processing apparatus
55200 receives a 2D image signal from the image source 55300 in
operation S55441, the second controller 55270 identifies the
received image signal as a 2D image signal in operation S55443,
processes the received 2D image signal in operation S55445, and
controls the second image processing unit 55220 to convert the
processed 2D image signal into a 3D image signal in operation
S55447. The second controller 55270 transmits the converted 3D
image signal to the display apparatus 55100 in operation S55448.
The first controller 55170 displays a 3D image based on the
received 3D image signal on the display unit 55130 in operation
S55449.
[0482] FIG. 43 is distinguished from FIG. 42 in that the first
image processing unit 55120 processes a 2D image signal. As shown
in FIG. 43, when the 3D image processing apparatus 55200 receives a
2D image signal from the image source 55300 in operation S55451,
the second controller 55270 identifies the received image signal as
a 2D image signal in operation S55453 and transmits the received 2D
image signal to the display apparatus 55100 in operation S55454.
The first controller 55170 controls the first image processing unit
55120 to process the received 2D image signal in operation S55455
and transmits the processed 2D image signal to the 3D image
processing apparatus 55200 in operation S55456. The second
controller 55270 controls the second image processing unit 55220 to
convert the processed 2D image signal into a 3D image signal in
operation S55457. The second controller 55270 transmits the
converted 3D image signal to the display apparatus 55100 in
operation S55458. The first controller 55170 displays a 3D image
based on the received 3D image signal on the display unit 55130 in
operation S55459.
[0483] As described above, according to the exemplary embodiments,
the 3D image processing apparatus 55200 is detachably coupled to
the display apparatus 55100 processing a 2D image, thereby
conveniently upgrading the display apparatus 55100 to reproduce 3D
contents.
[0484] Although a few exemplary embodiments have been shown and
described, it will be appreciated by those skilled in the art that
changes may be made in these exemplary embodiments without
departing from the principles and spirit of the inventive concept,
the scope of which is defined in the appended claims and their
equivalents.
