DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Preferred embodiments of the present invention will now be
described in detail in accordance with the accompanying
drawings.
[0022] An embodiment of the present invention will be described
below.
First Embodiment
[0023] FIG. 1 is a block diagram showing the overall configuration
of a network camera system according to the first embodiment of the
present invention. The network camera system shown in FIG. 1
includes a camera apparatus (image capturing apparatus) 1,
recording apparatus 2, display apparatus 3, and network 4.
[0024] The camera apparatus 1 includes an image capturing unit 11
which captures an image, and a network I/F 12 which
transmits/receives information through the network 4. The image
capturing unit 11 includes an A/D converter to A/D-convert an image
signal from an image sensing element such as a CCD, an image
processing circuit to execute, e.g., chrominance signal processing
and compression processing, and a control circuit to control the
image capturing unit 11. The recording apparatus 2 includes a
recording unit 21 which records and stores images from the camera
apparatus 1, and a network I/F 22 which transmits/receives
information through the network 4. The recording apparatus 2
includes a nonvolatile memory such as a hard disk, and a recording
control circuit to read/write an image from/in a memory in
accordance with an external request signal.
[0025] The display apparatus 3 transmits/receives information
through the network 4. The display apparatus 3 has a network I/F
31, a control unit 32 which controls the acquisition source of
images to be displayed, and a display unit 33, like a Liquid
Crystal Display, which displays a plurality of acquired images on a
screen. The display apparatus 3 also has a layout storage unit 34
which stores layout information containing an image layout on a
screen, the correspondence between each image and the camera
apparatus 1, and time designation. The display apparatus 3 also
includes a layout reconstruction unit 35 which reconstructs display
on the display unit 33 from layout information stored in the layout
storage unit 34 having a nonvolatile memory, and an image capturing
time calculation unit 36 which calculates an image capturing time
from a time designation in layout information.
[0026] The display apparatus 3 includes an operation unit 38 having
a mouse and a keyboard to input a user instruction to set layout
information. The processing operations of the control unit 32,
layout reconstruction unit 35, and image capturing time calculation
unit 36 are executed by a single processing unit. In this case, the
processing unit reads out a program stored in the ROM to the RAM
and executes the processing operations of the control unit 32,
layout reconstruction unit 35, and image capturing time calculation
unit 36 on the basis of the program. The processing operations of
the control unit 32, layout reconstruction unit 35, and image
capturing time calculation unit 36 can also be executed by
different control circuits.
[0027] FIG. 2A shows an example of a screen displayed on the
display unit 33. On this screen, the position and size of each
image region to display an image can freely be set. A plurality of
images captured by the single camera apparatus 1 at different times
can also be displayed simultaneously. The image regions to display
images can overlap.
[0028] FIG. 2B shows an example of layout information stored in the
layout storage unit 34 in correspondence with the screen in FIG.
2A. In the layout information, each of image regions 1 to 5 is
associated with camera apparatus information, arrangement
information, size information, and image capturing time information
of an image captured by the camera apparatus 1 as an image
capturing apparatus.
[0029] The "camera apparatus" information represents a camera
apparatus which has captured an image to be displayed in each of
image regions 1 to 5. The "arrangement information (position
information)" represents the arrangement of each of image regions 1
to 5 on a display region 5. The "size" represents the size of an
image to be displayed in each of image regions 1 to 5. The
information of "image capturing time of an image to be reproduced"
represents whether a display target image is an image which is
currently being captured by the camera apparatus 1. When the
display target image is a recorded image, this information
represents the image capturing time of the recorded image to be
reproduced.
[0030] FIG. 3 shows a setting example of image capturing time
information of an image to be reproduced in the layout information
and the image capturing time calculation method by the image
capturing time calculation unit 36 corresponding to the contents of
the setting example. The information of "image capturing time of an
image to be reproduced" in the layout information shown in FIG. 2B
is represented by a combinations of settings shown in FIG. 3.
[0031] If, e.g., "Live" is set as the image capturing time
information of an image to be reproduced, processing of
successively acquiring images captured by the camera apparatus 1
from it and reproducing the images is set.
[0032] If, e.g., "08:00" is set as the image capturing time
information of an image to be reproduced, reproduction of a stored
image which has been captured at the past set time nearest to the
current time is set. In the example shown in FIG. 3, the current
time is 7:00 on Dec. 13, 2004. Hence, reproduction processing of a
recorded image captured at 8:00 on Dec. 12, 2004 is set.
[0033] If, e.g., "-01:00" is set as the information of "image
capturing time of an image to be reproduced", reproduction of a
stored image which has been captured the set time (i.e., one hour)
ago from the current time is set.
[0034] If, e.g., "2004/12/24 12:00" is set as the information of
"image capturing time of an image to be reproduced", reproduction
of a stored image which has been captured at the set time (i.e.,
12:00 on Dec. 24, 2004) is set.
[0035] If, e.g., "Mon-Fri 17:00" is set as the information of
"image capturing time of an image to be reproduced", reproduction
of a recorded image at the past set time nearest to the current
time is set. In the example shown in FIG. 3, a stored image
captured at 17:00 from Monday to Friday nearest to the current time
is set.
[0036] In this embodiment, a region to display an image from each
camera apparatus 1 is set on the screen by the user's operation.
The image capturing time information of the image to be reproduced
is set for each image. Upon detecting a storage instruction from
the user, the control unit 32 stores the set information in the
layout storage unit 34 as layout information. The layout storage
unit 34 can store a plurality of pieces of layout information. The
user can avoid re-setting in every activation of the display
apparatus 3 by invoking the layout information.
[0037] The operation of the display apparatus 3 according to this
embodiment will be described next with reference to the flowchart
in FIG. 10 which is executed by the control unit 32 of the display
apparatus.
[0038] The control unit 32 detects that the user has selected, on a
menu window shown in FIG. 11, a desired one of a plurality of
pieces of layout information stored in the layout storage unit 34
(YES in step S1001). The control unit 32 reads out the selected
layout information from the layout storage unit 34. The layout
reconstruction unit 35 reconstructs image display regions on the
screen.
[0039] It is determined whether the information of "image capturing
time of an image to be reproduced" in the selected layout
information is "Live". When reproduction display of an image that
is currently being captured by the camera apparatus 1 is set (YES
in step S1002), the control unit 32 accesses the camera apparatus 1
on the basis of its address information that is associated with the
layout information in advance and acquires the image (step
S1004).
[0040] On the other hand, if the image capturing time information
of an image to be reproduced in the selected layout information
designates reproduction of a recorded image, like "08:00",
"-01:00", "2004/12/24 12:00", or "Mon-Fri 17:00" in the
above-described example (NO in step S1002), the flow advances to
step S1003. In step S1003, the image capturing time calculation
unit 36 calculates the image capturing time of the image on the
basis of the current time and the image capturing time information
of the image to be reproduced.
[0041] The control unit 32 acquires, from the recording apparatus
2, a recorded image at the image capturing time calculated by the
image capturing time calculation unit 36 of the camera
corresponding to the camera information in the selected layout
information (step S1004). The address information of the recording
apparatus 2 to be accessed to acquire the image is associated with
the layout information in advance.
[0042] The display unit 33 displays the image acquired by the
control unit 32 in a corresponding region on the screen on the
basis of the layout information in the selected layout information
(step S1005).
[0043] The system configuration shown in FIG. 1 can also be applied
to a configuration which connects a plurality of camera apparatuses
1 and a plurality of recording apparatuses 2 through the network
4.
[0044] In this network configuration, images from the camera
apparatuses 1 may be stored in a representative one of the
plurality of recording apparatuses 2 or stored in each recording
apparatus 2. The recording apparatus 2 and display apparatus 3 may
be integrated.
[0045] When it is detected that the user has selected, on the menu
window shown in FIG. 11, a desired one of the pieces of layout
information stored in the layout storage unit 34, the selected
layout information is read out from the layout storage unit 34. The
layout reconstruction unit 35 reconstructs image display regions on
the screen.
[0046] When display of a currently captured image is set as the
image capturing time information of an image to be reproduced in
the selected layout information, the control unit 32 acquires a
live image from the camera apparatus 1 corresponding to the camera
information set in the selected layout information.
[0047] When display of a recorded image is designated by the
information of "image capturing time of an image to be reproduced"
in the selected layout information, the control unit 32 acquires,
from the representative recording apparatus 2, correspondence
information between the camera apparatus 1 and the recording
apparatus 2 which records the image of the camera apparatus 1. The
control unit 32 acquires the image from the recording apparatus 2
on the basis of the correspondence information.
[0048] With such processing, the display unit 33 can display the
image acquired by the control unit 32 in a region designated by the
arrangement information in the layout information.
Second Embodiment
[0049] The second embodiment will be described next.
[0050] In the second embodiment, a form which causes a recording
apparatus 2 to serve as a relay server will be described. FIG. 4 is
a block diagram showing the configuration of a network camera
system according to this embodiment. As shown in FIG. 4, the
configuration of the network camera system of this embodiment is
the same as that shown in FIG. 1 except that a control unit 23 is
added to a recording apparatus 2. The control unit 23 controls the
image acquisition source on the side of the recording apparatus 2.
The control unit 23 includes a ROM to store a program, a RAM to
temporarily store the program read out from the ROM, and a
processing unit to control the entire recording apparatus 2 on the
basis of the program temporarily stored in the RAM.
[0051] It is detected that the user has selected, on a menu window
shown in FIG. 11, a desired one of pieces of layout information
stored in a layout storage unit 34. Upon this detection, a layout
reconstruction unit 35 reconstructs image display regions on the
screen in accordance with the selected layout information.
[0052] When the information of "image capturing time of an image to
be reproduced" in the selected layout information sets reproduction
of a recorded image, an image capturing time calculation unit 36
calculates the image capturing time of the image on the basis of
the current time and the information of "image capturing time of
the image to be reproduced".
[0053] To acquire the reproduction target image, a control unit 32
transmits the calculated image Capturing time and camera
information in the layout information to the recording apparatus 2
which has recorded the image captured by a camera apparatus 1.
[0054] When the image capturing time information of an image to be
reproduced in the selected layout information designates display of
an image which is currently being captured by the camera apparatus
1, the control unit 32 transmits information representing live
image reproduction and camera information in the layout information
to the recording apparatus 2.
[0055] Upon receiving the image capturing time from a display
apparatus 3, the control unit 23 acquires, from a recording unit
21, the image of the camera apparatus 1 indicated by the camera
information at the image capturing time and transmits the image to
the display apparatus 3.
[0056] Upon receiving the information representing live image
reproduction from the display apparatus 3, the control unit 23
acquires the image from the camera apparatus 1 indicated by the
camera information and transmits the image to the display apparatus
3. The display apparatus 3 causes a display unit 33 to display the
image received from the recording apparatus 2 in a region
designated by arrangement information in the layout
information.
Third Embodiment
[0057] The third embodiment will be described next.
[0058] In the third embodiment, layout information is created in
response to sensor detection.
[0059] FIG. 5 is a block diagram showing the configuration of a
network camera system according to the third embodiment. As shown
in FIG. 5, the configuration of the network camera system of this
embodiment is the same as that shown in FIG. 1 except that a sensor
unit 13 is added to a camera apparatus 1, and a recording control
unit 24 and layout creation unit 25 are added to a recording
apparatus 2.
[0060] The sensor unit 13 comprises a sensor such as a photosensor,
sonic sensor, or temperature sensor to detect a change in the
situation around the camera apparatus 1. The sensor unit 13 may
include a notification by image analysis such as motion detection,
person detection, face detection, or color detection from a
captured image or a combination thereof.
[0061] The recording control unit 24 changes recording settings
such as the frame rate, size, and quality of an image from the
camera apparatus 1, which is to be recorded in a recording unit 21,
in accordance with a state change notification from the sensor unit
13.
[0062] The layout creation unit 25 creates layout information in
accordance with a notification from the sensor unit 13 and
transmits the created information to a layout storage unit 34.
Various settings shown in FIGS. 2A and 2B which are necessary for
creating the layout information are stored in the layout creation
unit 25.
[0063] Pieces of associated information of a plurality of camera
apparatuses 1 are stored in the layout creation unit 25. The
associated information includes the information of camera
apparatuses capturing the same object from different directions,
camera apparatuses installed in the same corridor in a building, or
image capturing apparatuses installed in different floors of a
flight of stairs. These pieces of information are set in
advance.
[0064] Upon receiving a notification from the sensor unit 13, the
layout creation unit 25 creates layout information to reproduce an
image from the camera apparatus 1 that has transmitted the
notification. More specifically, the layout creation unit 25
creates layout information containing the notification time or a
time a predetermined time ago from the notification time as the
image capturing time information of the to-be-reproduced image of
the camera apparatus 1.
[0065] The layout creation unit 25 also creates layout information
to reproduce an image from each camera apparatus associated with
the camera apparatus 1 whose sensor unit 13 has transmitted the
notification. More specifically, the layout creation unit 25
creates layout information containing the notification time or a
time a predetermined time ago from the notification time as the
image capturing time information of the to-be-reproduced image of
each camera apparatus associated with the camera apparatus 1.
[0066] Layout information containing the live images of the camera
apparatus 1 and each camera apparatus associated with the camera
apparatus 1 may be created.
[0067] The processing operations of the recording control unit 24
and the layout creation unit 25 are executed by a single processing
unit. In this case, the processing unit reads out a program stored
in the ROM to the RAM and executes the processing operations of the
recording control unit 24 and the layout creation unit 25 on the
basis of the program.
[0068] FIG. 7 is a table showing an example of the associated
information of the camera apparatuses 1. In the example shown in
FIG. 7, the camera apparatuses 1 are classified on the basis of two
pieces of information: zone and location.
[0069] More specifically, camera apparatuses in the same zone as
the camera apparatus whose sensor unit 13 has transmitted a
notification and camera apparatuses in the same location as the
camera apparatus that has transmitted a notification are assumed as
associated camera apparatuses.
[0070] The associated camera apparatuses may be camera apparatuses
that satisfy a reference condition designated by the user through
the display apparatus 3. In designating camera apparatuses which
are installed in the same zone as the camera apparatus that has
transmitted the notification and satisfy a specific reference
condition, for example, assume that the camera apparatus 1 with the
sensor unit 13 having transmitted a notification is camera 06, and
"parking area" is designated as the reference condition. In this
case, the association targets are cameras 07 to 11.
[0071] In designating camera apparatuses which are installed in the
same location as the camera apparatus that has transmitted the
notification and satisfy a specific reference condition, for
example, assume that the camera apparatus that has transmitted a
notification is camera 03, and "elevator hall" is designated as the
reference condition. In this case, the association target is camera
04.
[0072] The associated camera apparatuses may be camera apparatuses
that satisfy a join of the above-described conditions or camera
apparatuses that satisfy a meet of the above-described
conditions.
[0073] The layout information thus created by the layout creation
unit 25 is transmitted to a display apparatus 3 and stored in a
layout storage unit 34. A control unit 32 of the display apparatus
3 acquires the image to be reproduced from the camera apparatus 1
to recording apparatus 2 on the basis of the stored layout
information. A display unit 33 displays the acquired image.
[0074] Layout creation by the layout creation unit 25 may be done
every time a predetermined time elapses from detection of the
sensor unit 13. In this case, the layout creation unit 25 stores
the log of notifications from the sensor unit 13 of each camera
apparatus 1.
[0075] When a notification from the sensor unit 13 is received
after the elapse of a predetermined time, layout information
containing the notification time as the image capturing time
information of the to-be-reproduced image of the camera apparatus 1
is created. In addition, on the basis of the notification log, the
layout creation unit 25 creates layout information containing the
notification times of several close, past notifications as the
image capturing time of the to-be-reproduced image of the camera
apparatus 1.
[0076] Layout creation may be done on the side of the display
apparatus 3, as shown in FIG. 6. The configuration of the network
camera system of this embodiment is the same as that shown in FIG.
5 except that the layout creation unit 25 is removed from the
recording apparatus 2, and a layout creation unit 37 is added to
the display apparatus 3.
[0077] Layout information to display images in a display region 5,
which should be created as the layout information, is created by
using layout information set in advance in correspondence with the
number of images to be displayed.
Fourth Embodiment
[0078] The fourth embodiment will be described next. The
configuration shown in FIG. 5 or 6 is applied to a network camera
system according to the fourth embodiment.
[0079] FIG. 8 is a view showing an example of an image display
composition on a display unit 33. A display region 5 is a region
displayed on the display unit 33 and includes a specific region 51.
Image regions a52, b53, c54, d55, and e56 are regions to reproduce
and display an image captured by a camera apparatus.
[0080] FIG. 9 is a table showing an example of layout format
information. The layout format information contains at least the
layout order information of images in the image regions, the layout
position information of the image regions, and the size information
of the image regions. When the layout format information is created
in response to a user operation, the layout format information is
stored in a layout creation unit 25 shown in FIG. 5 or layout
creation unit 37 shown in FIG. 6.
[0081] The form of this embodiment creates layout format
information on the basis of the degree of association to a camera
apparatus having a sensor unit 13 that has transmitted a
notification.
[0082] For example, the display unit 33 displays, in the specific
region 51, the image of the camera apparatus that has transmitted a
notification. Assume that camera apparatuses a, b, and c are
present as camera apparatuses associated with the camera apparatus
that has transmitted the notification, and the degree of
association becomes high in the order of camera apparatuses c, b,
and a. When the degree of association becomes high in the order of
image regions a, b, and c, it is decided to display the image from
the camera apparatus c in the image region a, the image from the
camera apparatus b in the image region b, and the image from the
camera apparatus a in the image region c.
[0083] According to the above-described embodiments, the layout of
images from cameras on the screen in steady browsing and the image
capturing time of each camera are obtained. On the basis of these
pieces of information, the images can be displayed on the display
unit. Hence, the user operation can be simplified.
[0084] The object of the present invention can also be achieved by
supplying a storage medium which records software program codes for
implementing the functions of the above-described embodiments to
the camera apparatus 1, recording apparatus 2, and display
apparatus 3 and causing the computer (or CPU or MPU) of the system
or apparatus to read out and execute the program codes stored in
the storage medium.
[0085] In this case, the program codes read out from the storage
medium implement the functions of the above-described embodiments
by themselves, and the storage medium which stores the program
codes constitutes the present invention.
[0086] As the storage medium to supply the program codes, for
example, a flexible disk, hard disk, optical disk, magnetooptical
disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, ROM,
and the like can be used.
[0087] The functions of the above-described embodiments are
implemented not only when the readout program codes are executed by
the computer but also when the OS (fundamental system or operating
system) running on the computer performs part or all of actual
processing on the basis of the instructions of the program
codes.
[0088] The functions of the above-described embodiments are also
implemented when the program codes read out from the storage medium
are written in the memory of a function expansion board inserted
into the computer or a function expansion unit connected to the
computer, and the CPU of the function expansion board or function
expansion unit performs part or all of actual processing on the
basis of the instructions of the program codes.
[0089] As many apparently widely different embodiments of the
present invention can be made without departing from the spirit and
scope thereof, it is to be understood that the invention is not
limited to the specific embodiments thereof except as defined in
the claims.
[0090] This application claims the benefit of Japanese Patent
Application No. 2005-137807 filed on May 10, 2005, which is hereby
incorporated by reference herein in its entirety.
