DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0040] Hereinafter, exemplary embodiments will be described more
fully with reference to the accompanying drawings. Exemplary
embodiments may, however, be embodied in many different forms and
should not be construed as being limited to the exemplary
embodiments set forth herein; rather, these exemplary embodiments
are provided so that this disclosure will be thorough and complete,
and will fully convey the inventive concept to those skilled in the
art. In the drawings, like reference numerals denote like elements.
Hereinafter, expressions such as "at least one of," when preceding
a list of elements, modify the entire list of elements and do not
modify the individual elements of the list.
[0041] First, core ideas of one or more exemplary embodiment will
be schematically described with reference to FIG. 1.
[0042] FIG. 1 is a flowchart schematically illustrating a method of
displaying a photo on a screen having any shape, according to an
exemplary embodiment.
[0043] Referring to FIG. 1, a photo having a first shape is
obtained by using a digital photographing device, and photographing
information about the obtained photo having the first shape is
extracted in operation S110.
[0044] Here, the digital photographing device may be an image
processing apparatus, such as a digital camera, a personal digital
assistant (PDA), a personal multimedia player (PMP), a mobile
device, a tablet device, a computer, etc.
[0045] The photographing information may be read from a digital
photo file corresponding to the photo obtained by the digital
photographing device, and may include at least one of camera
information, lens information, focal length information, and focus
information.
[0046] An intention of a photographer is determined based on the
extracted photographing information, and the photo is adjusted to a
shape optimized to a screen having a second shape in operation
S120.
[0047] Here, the second shape denotes any shape different from the
first shape. For example, the first shape may be tetragonal and the
second shape may be circular, but the first and second shapes are
not limited thereto in other exemplary embodiments.
[0048] Also, the intention of the photographer may be determined to
determine whether the digital photo file is related to a person, an
object, a scenery, a focus object, a short range, or a long
range.
[0049] The adjusted photo is displayed on the screen having the
second shape in operation S130.
[0050] In summary, according to the current exemplary embodiment,
an intention of a photographer is determined by using photographing
information contained in a digital photo file or an image file, and
then a tetragonal photo may be displayed after being optimized to a
screen having any shape.
[0051] The present exemplary embodiment and other exemplary
embodiments may be applied to all products capable of displaying an
image, such as a screen having any shape, a circular electronic
frame, a television (TV), a mobile phone, a computer, a mobile
device, a tablet device, etc.
[0052] As a result, a value of a device may be increased by giving
a user a photo viewing experience different from a related art
technology by using a screen having a circular shape or the like,
instead of a tetragonal screen.
[0053] In addition, the method according to the present exemplary
embodiment can solve the problems described hereinafter with
reference to FIGS. 2A and 2B.
[0054] FIGS. 2A and 2B are diagrams for describing related art
methods of displaying a tetragonal image on a circular screen
without considering photographing information. In other words, in
FIGS. 2A and 2B, the related art methods display an image on a
screen having any shape without determining an intention of a
photographer by using photographing information.
[0055] Referring to FIG. 2A, a tetragonal photo is inscribed in a
circular screen even though the tetragonal photo is a photo of a
person. In other words, according to the related art method, the
inscribed tetragonal image is displayed on the circular screen in a
way that does not take advantage of the circular screen. Also, an
empty region that is not filled by the photo is generated in the
circular screen.
[0056] In FIG. 2B, in order to remove such an empty region, the
tetragonal photo is zoomed in to use all regions of the circular
screen.
[0057] However, according to such a related art method, all pieces
of information contained in the tetragonal photo are not displayed,
and thus there may be data loss of important information for a
user. Here, a region of the tetragonal photo containing important
information may be determined based on focus information obtained
when the user takes the photo with a digital photographing
device.
[0058] However, according to the related art method illustrated in
FIG. 2B, data of person information constituting important
information included in the tetragonal photo is lost.
[0059] The empty region and data loss of FIGS. 2A and 2B may be
resolved by frequently receiving an input about an intention of the
user. However, such frequent inputs may inconvenience the user,
specifically if a consumer electronic (CE) device for receiving the
inputs is spaced apart from the user.
[0060] Methods of displaying a photo optimized to a screen having
any shape by using photographing information according to one or
more exemplary embodiments will now be described in detail with
reference to FIGS. 3 through 11.
[0061] FIG. 3 is a block diagram schematically illustrating an
apparatus 300 for displaying a photo on a screen having any shape,
according to an exemplary embodiment.
[0062] Referring to FIG. 3, the apparatus 300 includes an image
extractor 310 for extracting photographing information about a
photo having a first shape, an image processor 320 for adjusting
the photo to a shape optimized to a screen having a second shape,
based on the extracted photographing information, and a displayer
330 for displaying the adjusted photo on the screen. The apparatus
300 may further include a storage unit (not shown) for storing the
photo having the first shape by using a digital photographing
device. It is understood that one or more other exemplary
embodiments are not limited to the above-described elements. For
example, an apparatus according to another exemplary embodiment may
be a processing apparatus which processes a photo and outputs,
through an output unit (not shown), the processed photo to be
displayed on one or more external display devices. In this case,
information regarding a screen of an external display device may be
received from the display device, may be input by a user, etc.
[0063] In the current exemplary embodiment, each of elements may be
formed on an individual chip or at least two elements may be formed
on a single chip.
[0064] The image extractor 310 may read the photo to be displayed
on the displayer 330 from the storage unit.
[0065] The image extractor 320 may extract the photographing
information from the photo. For example, the image extractor 310
may read focus information obtained when a user took the photo,
from the photo. Also, the image extractor 310 may read lens
information used when the user took the photo, and focal length
information of the photo, from the photo. However, it is understood
that one or more other exemplary embodiments are not limited to the
above construction. For example, according to another exemplary
embodiment, the photographing information may be determined from a
separate file or information, separate from the photo.
[0066] The image processor 320 may determine whether the photo is a
short range photo, based on the photographing information. Also,
the image processor 320 may determine an important region
containing the focus information in the photo.
[0067] The image processor 320 may use the focus information while
determining whether the photo is a short range photo. For example,
the image processor 320 determines that the photo is a long range
photo if the focus information is distributed throughout the photo,
and determines that the photo is a short range photo if the focus
information is limited to a partial region of the photo.
[0068] Alternatively, the image processor 320 may determine whether
the photo is a short range photo by using the lens information and
the focal length information. A detailed description of a
correlation between a focal length and a view angle will now be
provided with reference to FIG. 4.
[0069] By using the correlation shown in FIG. 4, a view angle
determined according to a certain focal length is obtained, and
thus it may be determined whether a user photographed a close
subject, such as a person, or a far off subject, such as scenery,
by using the photographing information obtained from the photo.
[0070] For example, if the user used a 18 to 55 mm lens, it may be
determined that the user tried to photograph a near object if a
focal length is close to 55 mm, and far scenery if the focal length
is close to 18 mm.
[0071] The intention of the user may be more accurately determined
by using the lens information and the focus information together.
As such, it is determined whether the photo is a short range photo
or a long range photo, and the important region in the photo is
determined accordingly.
[0072] Referring back to FIG. 3, if the photo is a long range
photo, the image processor 320 adjusts the photo to be displayed
throughout the screen.
[0073] On the other hand, if the photo is a short range photo, the
image processor 320 may zoom in the important region of the photo
containing the focus information so that the important region is
disposed in a center of the screen.
[0074] The displayer 330 displays the photo adjusted by the image
processor 320 on the screen.
[0075] FIG. 5 is a flowchart illustrating in detail a method of
displaying a photo on a screen having any shape, according to an
exemplary embodiment.
[0076] For convenience of description, the screen according to the
present exemplary embodiment has a circular shape, though it is
understood that the screen may have any shape, such as a tetragonal
shape, a triangular shape, a hexagonal shape, etc., according to
one or more other exemplary embodiments.
[0077] In operation 510, the image extractor 310 reads a photo to
be displayed on a circular screen from the storage unit.
[0078] In operation 520, the image processor 320 determines whether
existing input information from a user about a method of displaying
the photo on the circular screen is possessed (i.e., received or
stored).
[0079] If the existing input information is possessed, the image
processor 320 adjusts the photo to be displayed on the circular
screen according to the existing input information in operation
S530.
[0080] On the other hand, if the existing input information is not
possessed, the image processor 320 determines whether a photo file
corresponds to the photo contains photographing information in
operation S540.
[0081] If the photo file contains the photographing information,
the image processor 320 determines (e.g., predicts) an intention of
a photographer by reading the photographing information in
operation S550.
[0082] If it is determined that the photographer intended to take a
long range photo in operation S560, the image processor 320
displays the photo throughout the circular screen in operation
S570.
[0083] On the other hand, if it is determined that the photographer
intended to take a short range photo in operation S560, the image
processor 320 adjusts the photo so that an important region of the
photo is disposed on a center of the circular screen by using focus
information in operation S580.
[0084] As such, the image processor 320 adjusts the photo to a
shape optimized to the circular screen (operations S530, S570, and
S580), and the displayer 330 displays the adjusted photo on the
circular screen in operation S590.
[0085] FIGS. 6 through 8 are diagrams for describing methods of
displaying a photo on a screen having any shape, according to one
or more exemplary embodiments. In FIGS. 6 through 8, important
information, e.g., focus information obtained when a user takes a
photo, is displayed in dotted lines.
[0086] Referring to FIG. 6, the image processor 320 determines that
the user photographed a subject in a short range and important
information of the photo is in a right region by analyzing data in
a photo file (or an image file).
[0087] Accordingly, the image processor 320 zooms the photo in so
that the right region is disposed on the center of the circular
screen.
[0088] Meanwhile, referring to FIG. 7, the image processor 320
determines that the user photographed a subject in a long range and
important information of the photo is in a center and a right
bottom region by analyzing data in a photo file.
[0089] Accordingly, the image processor 320 zooms the photo in so
that the center and the right bottom region of the photo are
disposed on the center of the circular screen.
[0090] Meanwhile, referring to FIG. 8, the image processor 320
determines that the user photographed a subject in a long range and
important information of the photo is throughout the photo by
analyzing data in a photo file.
[0091] Accordingly, the image processor 320 displays the photo
throughout the circular screen instead of zooming the photo in, if
it is determined that the photo is about scenery instead of a
person based on photographing information.
[0092] As described with reference to FIGS. 6 through 8, the method
and the apparatus 300 according to one or more exemplary
embodiments may be used in a display device having a shape
different from that of a photo. However, the method and the
apparatus 300 may also be used in a display device having the same
shape as that of a photo.
[0093] In other words, the method and the apparatus 300 may be used
to display a photo in a related art display device by preparing a
screen having any shape.
[0094] In other words, a screen described in the specification
denotes an image viewing region having any shape in a display
device.
[0095] FIGS. 9A through 9C are diagrams for describing methods of
displaying a photo on a screen having any shape, according to
another exemplary embodiment.
[0096] Referring to FIGS. 9A through 9C, when a circular region is
used as an image viewing region in a related art tetragonal display
device, the apparatus 300 displays an image optimized to the image
viewing region by using, for example, any of the methods described
with reference to FIGS. 6 through 8.
[0097] Since the photographing information and the methods of
displaying a photo according to the photographing information of
FIGS. 9A through 9C are respectively identical or similar to those
of FIGS. 6 through 8, except that a tetragonal display device is
used in FIGS. 9A through 9C and a circular display device is used
in FIGS. 6 through 8, detailed descriptions thereof will not be
repeated herein.
[0098] FIG. 10 is a flowchart schematically illustrating a method
of displaying a photo on a screen having any shape, according to
another exemplary embodiment.
[0099] Referring to FIG. 10, the image processor 320 determines
that a photo having a first shape is a long range photo based on
photographing information in operation S1110. A method of
determining a long range photo according to the present exemplary
embodiment may be the same as or similar to the method described
with reference to FIGS. 3 through 5.
[0100] In operation 1120, the image processor 320 adjusts the photo
to be displayed throughout a screen having a second shape.
[0101] Here, an empty region may be generated in the screen as the
photo is inscribed in the screen. Accordingly, the image processor
320 fills a remaining portion excluding a portion corresponding to
the photo in the screen with an image obtained by copying at least
a part of the photo in operation S1130. In other words, the image
processor 320 copies original information of the photo to the
remaining portion without losing the original information.
[0102] The displayer 330 displays the photo and the remaining
portion filled with the copied image on the screen in operation
S1140.
[0103] FIG. 11 is a diagram for describing a method of displaying a
photo on a screen having any shape, according to another exemplary
embodiment. A circular screen is shown in FIG. 11, but the method
may be applied to a screen having any shape, such as a tetragonal
screen, a triangular screen, a hexagonal screen, etc. Also, the
method of the current exemplary embodiment may be used to display
an image optimized to a region having any shape when the region is
used as an image viewing region in a related art tetragonal display
device.
[0104] Referring to FIG. 11, the image processor 320 determines
that a user photographed a subject in a long range and important
information of the photo is throughout the photo by analyzing data
in a photo file corresponding to the photo.
[0105] Here, if it is determined that the photo taken by the user
is of scenery instead of a person based on photographing
information, the image processor 320 displays the photo on the
screen by showing an entire region of the photo, instead of zooming
the photo in.
[0106] When the scenery is inscribed in the circular screen, an
empty region may be generated in the circular screen. Thus, the
image processor 320 may fill the empty region with a background
identical to a peripheral portion of the photo via an image
process.
[0107] One or more exemplary embodiments can also be embodied as
computer readable codes on a computer readable recording medium.
The computer readable recording medium is any data storage device
that can store data which can be thereafter read by a computer
system. Examples of the computer readable recording medium include
read-only memory (ROM), random-access memory (RAM), CD-ROMs,
magnetic tapes, floppy disks, optical data storage devices, etc.
The computer readable recording medium can also be distributed over
network coupled computer systems so that the computer readable code
is stored and executed in a distributed fashion. Also, functional
programs, codes, and code segments for accomplishing an exemplary
embodiment can be easily construed by programmers skilled in the
art to which the exemplary embodiment pertains.
[0108] While exemplary embodiments have been particularly shown and
described above, it will be understood by those skilled in the art
that various changes in form and details may be made therein
without departing from the spirit and scope of the inventive
concept as defined by the appended claims. The exemplary
embodiments should be considered in descriptive sense only and not
for purposes of limitation. Therefore, the scope of the inventive
concept is defined not by the detailed description of exemplary
embodiments, but by the appended claims, and all differences within
the scope will be construed as being included in the present
invention.
