  FIG. 1 shows an embodiment of the present invention and is a block diagram showing an electrical configuration of a digital still camera.

  The overall operation of the digital still camera is controlled by the control circuit 10.

  The digital still camera is provided with buttons 2 such as a power button, a shutter release button, and a mode switch. The output signal from the buttons 2 is input to the control circuit 10. The mode switch sets the shooting mode, playback mode (normal playback mode and 3D playback mode), and the like.

  The control circuit 10 includes a clock 11 for measuring the date and time, an operation program, data indicating the user's address, a memory 12 for storing other data, and a GPS circuit for detecting the position where the digital still camera is present. 13 is also connected.

  The digital still camera according to this embodiment can communicate with other devices. For this purpose, a communication control circuit 3 and a communication circuit 4 are provided in the digital still camera. An operation program for controlling operations described later can also be received by the communication circuit 4. The operation program received by the communication circuit 4 is given to the memory 12 via the communication control circuit 3 and the control circuit 10 and stored therein. However, when the operation program is stored in the memory card, the operation program can be read from the memory card and installed in the camera.

  When the photographing mode is set, the subject is photographed by the imaging circuit 1. Image data representing the subject image is input to the control circuit 10. In the control circuit 10, predetermined signal processing such as gamma correction and color balance adjustment is performed and input to the display control circuit 5. When the display device 6 is controlled by the display control circuit 5, the subject image is displayed on the display screen of the display device 6.

  When the shutter release button is pressed, image data representing the subject image is input to the control circuit 10 as described above. The control circuit 10 also receives data representing the shooting date and time measured by the clock 11, data indicating the user's address stored in the memory 12, and data indicating the shooting location detected by the GPS circuit 13. In the control circuit 10, an image file is generated, and image data, shooting date / time data, data indicating a user's address, shooting location data, and the like are stored in the generated image file. The generated image file is given to the memory card 8 via the memory interface 7 and recorded.

  When the normal playback mode is set, an image file representing a desired image is read from a number of image files recorded on the memory card 8. The read image file is given to the display control circuit 5 via the memory card interface 7 and the control circuit 10. When the display device 6 is controlled by the display control circuit 5, an image represented by the image file read from the memory card 8 is displayed on the display screen of the display device 6.

  When the three-dimensional playback mode is set, the image file recorded on the memory card 8 is read and input to the control circuit 10 via the memory card interface 7. In the control circuit 10, the display position is determined so as to be displayed at a position corresponding to the shooting location and the shooting time. The display device 6 is controlled by the display control device 5 so as to be displayed at the determined position. This three-dimensional playback mode will be described in detail later.

  FIG. 2 shows an example of the file structure (data structure) of an image file.

  The image file includes a header recording area and an image data recording area.

  In the image data recording area, image data obtained by photographing as described above is recorded.

  Header information such as image file management data is recorded in the header recording area. In particular, in this embodiment, as described above, data representing the shooting date and time, the shooting location, and the user's address are also recorded in the header recording area. The display method of the captured image represented by the image data can be changed using the shooting date and time, the shooting location, and the like.

  FIG. 3 is an example of an image displayed in the three-dimensional playback mode.

  In the three-dimensional reproduction mode, the shooting location image 31 is displayed on the display screen 30 of the display device 6. The photographic place image 31 has east, west, south, and north directions defined in four horizontal directions around the reference position C. For example, the right direction, the east direction, the downward direction, and the upward direction from the reference position C are the east direction, the west direction, the south direction, and the north direction, respectively. The vertical direction of the shooting location image 31 defines the shooting date and time. The reference position is the current position where the 3D playback mode is performed, but may be the home of the user of the digital still camera.

  In the three-dimensional playback mode, the position corresponds to the shooting location represented by the shooting location data stored in the image file read from the memory card 8 and to the position corresponding to the shooting date / time represented by the shooting date / time data. The captured images I1 to I29 represented by the image data stored in the image file are displayed.

  The shadow images i1 to i29 corresponding to these photographed images I1 to I29 are displayed at corresponding locations on the photographed ground image 31. The shadow images i1 to i29 appear as if they are shadows of the captured images I1 to I29. However, it is not necessary to display the shadow images i1 to i29. Shooting date and time lines L1 to L29 extending in the vertical direction of the shooting ground image 31 to the shooting ground image 31 are also displayed at the top left corners (shooting points) P1 to P29 of the captured images I1 to I29. Since the captured images I1 to I29 are displayed at positions according to the shooting date and time, the shooting date image 31 is displayed on the shooting date and time lines L1 to L29 with the origin (reproduction date and time) of the time axis of the shooting date and time. When considered as a surface, the older the shooting date and time, the shorter and the newer the shooting date and time, the longer. Of course, the photographing date and time lines L1 to L29 need not be displayed. Also, by changing the origin of the shooting date and time, the display position of the shot images I1 to I29 changes based on the shooting date and time based on the time of the origin, and shooting at a past or future position as viewed from the reference time. Images I1 to I29 can be displayed. For example, past photographed images viewed from the reference time are displayed below the photographed ground image 31.

  The shooting location image 31 defines a southeast region 31SE, a southwest region 31SW, a northwest region 31NW, and a northeast region 31NE. The captured images I1 to I5 are displayed in a portion indicating the solidified area with the southwest region 31SW, the captured images I11 and I12 are displayed in the portion indicating the solidified region with the northwest region 31NW, and the northeastern region 31NE is present. The captured images I21 to I29 are displayed in the portion indicating the hardened area. By looking at the captured images collected for each region, it is possible to estimate the movement route at the time of shooting by the photographer.

  FIG. 4 is a flowchart showing a processing procedure in the three-dimensional reproduction mode.

  The current position is calculated by the GPS circuit 13 (step 21). The calculated current position is set as a reference position, and a shooting location image is displayed (step 22).

  Subsequently, a large number of image files recorded on the memory card are read (step 23). The display position of the captured image is determined from the shooting date and time and the shooting location respectively represented by the shooting date and time data and shooting location data stored in the read image file (step 24). A captured image is displayed at the determined position (step 25). Since the display position of the photographed image depends on the photographing location and the photographing date and time, it is possible to know where and when the photographed image is obtained by confirming the position of the displayed photographed image. Also, the travel route of the photographer can be understood.

  FIG. 5 shows a modified example and is an example of an image displayed on the display screen.

  In the case shown in FIG. 3, the shooting location image 31 simply indicates east, west, north, and south, but in the case shown in FIG. 5, the shooting location image 32 is a map image centered on the reference position. By looking at the image on the map, the place name of the shooting location can be confirmed. The shooting location image 32 of the map is displayed by transmitting the current position information to the map server that transmits the map data, and the map server sends the image data representing the map corresponding to the position information to the digital still camera. This can be realized by transmitting.

  6 to 9 show another embodiment. In this embodiment, it is possible to have a simulated experience similar to the case where the photographer moves while moving. A photographed image obtained by photographing according to the photographing order is displayed on the display screen.

  FIG. 6 shows an image displayed in the three-dimensional playback mode.

  In this embodiment, as described above, the moving route of the photographer can be estimated from the photographed images I1 to I29. In this embodiment, the photographed images are displayed on the display screen in accordance with the photographing order. Therefore, by looking at the photographed images displayed on the display screen, the same viewpoint as that at the time of photographing by the photographer can be obtained. For example, when the photographer 35 moves to the photographing points P1 to P29 and obtains the photographed images I1 to I29, the photographed images I1 to I29 are displayed according to the photographing order.

  In the following description, two frames of captured images are sequentially displayed on the display screen, but one frame of captured images may be displayed, or three or more frames of captured images may be displayed. When three or more frames of captured images are displayed, the captured images are displayed from the bottom to the top in order from the oldest shooting date and time, and the size of the captured images decreases as they are displayed above.

  FIG. 7 is a flowchart showing a playback processing procedure.

  Two new image files having the latest shooting date and time are read from the memory card 8 (step 41). The size of the image is adjusted so that the image with the oldest shooting date is larger than the image with the newer shooting date among the two shot images represented by the read two-frame image file (step 42). Then, the positional relationship is determined so that the new image with the shooting date and time is displayed at the bottom of the display screen and the old image with the shooting date and time is displayed at the top of the display screen, and the new image and the old image are displayed (step 43). ). In addition, the display position is determined so that the positional relationship of the captured images is maintained. For example, assuming that the left direction of the display screen is defined as the west direction and the right direction of the display screen is defined as the east direction, the positional relationship between the two frames is determined from the relationship between these directions and the shooting location of the shot image. Is determined.

  FIG. 8 is an example of an image on which a new image and an old image are displayed.

  It is assumed that the left direction of the display screen is defined in the west direction, and the right direction of the display screen 30 is defined in the east direction.

  As described above, two image files are read from the memory card. The captured image 51 and the captured image 52 are displayed by the image file for two frames. The size of the image is adjusted so that one captured image 51 is larger than the other captured image 52. One captured image 51 is displayed at the bottom of the display screen 30, and the other captured image 52 is displayed at the top of the display screen 30. Furthermore, it is assumed that the shooting location of the shot image 51 is in the west direction from the shooting location of the shot image 52. For this reason, the captured image 51 is displayed on the left side (west side) of the captured image 52.

  Returning to FIG. 7, when the frame advance button is pressed (YES in step 44), if the command to shift to another mode is not given (NO in step 45), the next image file with the next shooting date / time will be stored in the memory. It is read from the card 8 (step 46).

  Shoot two frames so that the previous new image (which becomes the old image as a result of the new image file being read) is larger than the shot image represented by the newly read image file, and is located at the bottom. An image is displayed on the display screen (steps 42 and 43).

  FIG. 9 is an example of an image displayed on the display screen 30.

  As described above, a new image file is read from the memory card. An image represented by the newly read image file is taken as a captured image 53. The old photographed image 51 (see FIG. 8) with the photographing date and time is not displayed on the display screen 30. Since the photographed image 52 is older than the photographed image 53, the photographed image 52 is displayed larger than the photographed image 53 and displayed at the bottom.

  In this way, the captured image displayed on the display screen 30 is also updated by reading a new image file. Since the image of the old shooting date / time is large and displayed on the lower part of the display screen 30, the viewer can change the shooting location according to the shooting sequence of the photographer every time the shot image is updated. You can have a simulated experience like browsing.

  10 to 12 show still another embodiment.

  FIG. 10 shows an image displayed in the three-dimensional playback mode.

  In this embodiment, the photographed image is shown as if the viewer 36 is at the reference position C.

  FIG. 11 is a flowchart showing a playback processing procedure.

  First, the current position is calculated (step 61). An image file photographed in a predetermined direction (in this example, the north direction) from the current position is read from the memory card 8 (step 62). The image size is adjusted such that the larger the distance between the shooting location of the read image file and the reference position, the smaller the size of the shot image represented by the image file (step 63).

  Further, the left direction of the display screen is the west direction, the right direction is the east direction, and the vertical direction is assigned to the shooting date and time. The newer the shooting date, the more the shot image is displayed at the top of the display screen. Using the center of the bottom of the display screen as the reference position, the display position of the photographed image is determined from the photographing location and the photographing date and time (step 64). A captured image is displayed at the determined position (step 65).

  FIG. 12 is an example of an image displayed on the display screen 30.

  As described above, the left direction of the display screen 30 is defined as the west direction, and the right direction is defined as the east direction. The vertical direction of the display screen 30 corresponds to the shooting date and time. Further, the center 70 of the bottom side of the display screen 30 is set as a reference position.

  As described above, the display screen 30 displays the images 71 to 74 photographed at the photographing place in the north direction from the reference position. In addition, the size of these captured images 71 to 74 decreases as the distance from the reference position increases. Further, the photographed images 71 to 74 are positioned so that they are displayed at the top of the display screen 30 as the photographing date and time are newer.

  In this way, by displaying the captured images 71 to 74, it is possible to see a landscape where the viewer is at the reference position.
