JP 2004-343627 A (paragraph numbers [0026] to [0058])

  In recent years, digital cameras have become more sophisticated and less expensive. For example, when you travel to sightseeing spots, carry a digital camera. I often take snapshots against the background. Ideally, the image data shot in this way is printed on photographic paper and stored as an album. However, since captured image data captured by a digital camera can be easily displayed on a home computer, the captured image data is often viewed on a computer after a trip.

  In a long trip, captured image data captured by a digital camera may be stored across a plurality of media, and image data captured by a plurality of digital cameras may be viewed on a computer. In such a case, sorting the photographed image data in the order of photographing leads to natural viewing. Therefore, considering the process of sorting the photographed image data photographed by a plurality of digital cameras, when using the photographing date / time data by Exif, if the clock built in the digital camera is inaccurate, photographing by Exif The date and time data is also inaccurate, leading to the inconvenience that proper sorting cannot be performed.

  Taking the shooting date / time data by Exif as an example, the shooting date / time data can be changed by using a dedicated editor. However, considering that the process of changing the shooting date / time data for each of a plurality of shot image data is artificially performed, it takes too much time and there is room for improvement.

  An object of the present invention is to rationally change shooting date / time data associated with a plurality of shot image data.

A feature of the present invention is an image processing system including a processing device that performs image processing of captured image data acquired by an image data acquisition unit.
The processing device extracts shooting date and time data associated with each of a plurality of shooting image data acquired by the image data acquisition means,
This is because the photographing date / time data of the photographed image data is configured to be shifted by an equal value.

  Taking image data taken with a digital camera as an example, the Exif shooting date / time data is generated based on the date / time data from a clock built in the digital camera. The shooting date / time data attached to the plurality of shot image data shot by the camera is shifted by an equal value from the accurate time. On the other hand, according to the present invention, the shooting date and time data associated with each of the plurality of captured image data acquired by the image data acquisition unit is extracted and shifted by an equal value, thereby capturing the captured images associated with the plurality of captured image data. Date and time data can be set to an appropriate shooting date and time collectively. As a result, it has become possible to set shooting date / time data associated with a plurality of shot image data without trouble.

  In the present invention, when the processing device acquires captured image data captured by a plurality of digital cameras by the image data acquisition unit, the shift processing is performed on the plurality of captured image data captured by each digital camera. The processing form may be set so that the photographing date / time data is shifted by an equal value as a unit.

In the present invention, the shooting date / time data is Exif shooting date / time data,
The processing device includes link processing means for associating position data acquired by the position acquisition means with photographed image data acquired by the image data acquisition means by link data,
The position acquisition means is configured to acquire timing data for specifying a date and time when the position data is acquired;
The link processing means may set a processing form so as to associate the position data and the photographed image data from the photographing date / time data and the timing data.

  With this configuration, when the link processing unit associates the position data acquired by the position acquisition unit and the captured image data acquired by the image data acquisition unit with the link data, the date and time when the position acquisition unit acquires the position data. It is possible to specify from the timing data to be specified, and to associate the timing data with the shooting date / time data, and not only can be associated by automatic processing, but also high-accuracy association is realized.

  The present invention includes, as the link processing means, output control means for outputting map image data indicating the location of the position data and photographed image data associated with the position data by the link data to an output unit. Also good.

  With this configuration, it becomes possible for the output control means to associate the shooting position of the map image data with the shot image data and output it to the output unit, and the shot image is displayed on the map image data based on the output result from the output unit. The shooting position of data can be grasped.

  In the present invention, the position acquisition means is constituted by a GPS unit constituting a car navigation system, the map image data is constituted by map data used in the car navigation system, and the output control means is the car navigation system. You may comprise with the display to comprise.

  With this configuration, for example, by using a GPS unit that constitutes a car navigation system, photographed image data photographed with a digital camera with respect to position data traveled by a private car, such as when traveling by private car For example, the position on the map data where the photographed image data is photographed and the photographed image data can be displayed on the display.

  The position acquisition means L captures the radio wave from the GPS satellite received by the antenna unit A and simultaneously captures the vehicle speed pulse signal from the vehicle speed sensor S, thereby obtaining vehicle position data (longitude / latitude data) in real time. And the time when this position data was acquired is acquired as timing data. Further, the position acquisition means L may acquire position information by radio waves from a plurality of radio wave transmission sources on the ground, and may be a gyroscope that detects the attitude of the vehicle, or an acceleration sensor that detects the acceleration of the vehicle. Alternatively, the accuracy of the position information of the vehicle may be improved by using radio waves from a ground source.

  The hard disk HD has a function of storing photographed image data, functions as a map database of map data (an example of an image data storage unit) that stores map data of a preset area, and stores music data. It functions as a music database.

  The processing device D includes a semiconductor memory RAM / ROM connected to a data bus from a microprocessor, a nonvolatile memory EEPROM, a map matching means 11, a navigation means 12, a route storage means 13, an image data storage means 14, a link processing means. 15), output control means 16 and storage processing means 17. Incidentally, in order to realize control in this processing device D, a control bus and an address bus are required in addition to a data bus, but in order to avoid complication, the drawing shows a control bus and an address bus. Does not show interfaces.

  The map matching means 11 extracts map data corresponding to the position data from the position acquisition means L from the map database stored in the hard disk HD and displays it on the display C at a preset magnification. I do. The navigation means 12 extracts a route to a preset destination from the map data and displays the route on the map data in a line shape. Necessary operations such as a right turn and a left turn at a point such as an intersection are displayed on the display C. A process of displaying and outputting necessary operations such as a right turn and a left turn in the human language from the speaker 2 is performed.

  The route storage means 13 writes the position data acquired for each interval set by the position acquisition means L into the hard disk HD or the semiconductor memory RAM at each timing when each position data is acquired, so that the vehicle has traveled. A process of storing position data as a route is performed. Incidentally, when the route 110 stored in the route storage means 13 is displayed on the display C, it is displayed as shown by a broken line in FIG. 7, and a vehicle symbol 111 is shown on the route 110, and this route 110 The shooting point P described later is shown above.

  The image data storage processing means 14 performs processing for storing captured image data acquired via the semiconductor drive 8, the disk drive 9, or the input / output terminal 5 in the hard disk HD. When data is stored in the hard disk HD, a selection screen 20 that enables capturing of photographed image data is displayed on the display C as shown in FIG. 5, and a selection is made by designating a required image on the selection screen 20. It functions to store a plurality of captured image data (this function will be described later).

The timing data acquisition unit, the shooting date / time data acquisition unit, and the link data generation unit each function effectively when the captured image data is converted into an electronic album as described later.

  The Exif data is attached to the photographed image data as a header of a file constituting photographed image data photographed by the digital camera 105, and an example of the structure can be represented as shown in FIG. The main information of this Exif data stores the manufacturer name and model name of the digital camera. In addition to exposure time, image width, and image height data as sub-information, the original shooting date / time is year, month, day, time. Are stored in units of minutes and seconds, and the shooting date and time acquisition unit of the link processing unit 15 acquires the data of the original shooting date and time as shooting date and time data.

  The output control means 16 performs processing for displaying captured image data associated with position data on the display C.

  The storage processing unit 17 includes data of the selected route 110, a plurality of photographed image data associated with a plurality of position data (photographing points) existing on the route 110, map data corresponding to the route 110, When the associated music data exists, the music data is stored as an electronic album in a storage medium such as the disk-shaped medium Md (control form will be described later). A storage medium (for example, a DVD-R) in which data is stored as an electronic album can reproduce map data, photographed image data, and the like on a personal computer.

  When the storage medium storing the data as an electronic album is played back by a personal computer, the map data and the route 110 are displayed on the display as shown in FIG. 7, and the vehicle symbol 111 travels on the route 110. Each time the vehicle symbol 111 reaches the shooting point P by this simulation, a process of displaying the shot image data associated with the shooting point P (position data) on the display C is performed. It should be noted that the present invention is not intended only for electronic albums that are automatically reproduced, but simply stores route 110 data, photographed image data, map data, etc. By clicking or operating a specific key on the keyboard, an electronic album having a data structure that simply displays captured image data associated with each shooting point on the route 110 in the order of shooting is generated as an electronic album. It may be a thing.

  In the present invention, the map matching means 11, the navigation means 12, the route storage means 13, the image data storage means 14, the link processing means 15, the output control means 16, and the storage processing means 17 are software that can be developed on a semiconductor memory RAM. Although hardware (program) is assumed, part or all of the hardware (program) may be configured by hardware such as logic.

  The navigation system of the present invention displays the processing menu 30 shown in FIG. 4 on the display C by operating the switch 1 or the remote controller 3, and the album creation button 31 displayed on the processing menu 30 and the reproduction mode are displayed. The selected process can be executed by selecting a process in which the finger is brought into contact with any one of the play button 32 in the (simulation mode) and the play button 33 in the actual travel mode.

  Specifically, the creation of an electronic album is realized by operating the album creation button 31 in the processing menu 30. In this system, before the album creation button 31 is operated, the position where the vehicle has traveled Is automatically acquired, and a processing mode is set so as to acquire a plurality of captured image data at an arbitrary timing.

  That is, in the navigation system of the present invention, as shown in the flowchart of FIG. 10, every time the position acquisition means L acquires position data at a preset interval, the position data is acquired and stored (step # 01). An image data acquisition routine (step # 100) for acquiring captured image data at any timing is executed. Such a process is continuously performed until a process for creating an electronic album is selected (step # 02). When a process for creating an album is selected (when the album creation button 31 is operated). The link processing means 15 generates link data (step # 200), sets map data corresponding to position data associated with the photographed image data by the link data, sets a title, and sets music data. After that, the created electronic album is stored in the hard disk HD, and when the processing for storing in the medium is selected, the electronic album is stored in the disk-shaped medium Md (for example, DVD-R) as the storage medium. The storing process is performed (# 03 to # 05, steps # 300).

  As shown in the flowchart of FIG. 11, the image data acquisition routine (# 100 step) grasps the situation where the captured image data can be acquired as in the case where the storage medium Md is set in the semiconductor drive 8. Only when the selection is made, the selection screen 20 shown in FIG. 5 is displayed on the display C (steps # 101 and # 102). The selection screen 20 displays all the captured image data stored in the storage medium in the thumbnail format in the image display area 21. By operating the scroll bar 22, all the captured image data is displayed. Can be confirmed. Of the photographed image data displayed in the image display area 21 as described above, information 23 that has been determined to be already stored based on the file number of the photographed image data is attached with information 23 such as <stored>. The processing mode is set so that all remaining captured image data except the already stored captured image data is automatically selected as a storage target (step # 103).

  For those that are not automatically reflected from the ones that were automatically selected as described above, or those that are judged to be unnecessary for the album, the selection button is used after the operator designates the captured image data in contact with the finger. The selection can be canceled by operating the finger 24 in contact with the finger. When the selection is performed again after the selection is canceled, the selection switch 25 can be operated to select the selection. In addition, when the rotation button 26 is operated after the photographed image data is designated, the designated photographed image data can be rotated in units of 90 degrees. After the selection is made as described above, the selected photographed image data is stored in the hard disk HD (step # 105) by operating the OK button 27 (step # 104). The process for selecting the photographed image data is realized by the operation via the touch panel unit 7 of the display C. However, the photographed image data is designated by operating the switch 1 or the remote controller 3. The interface may be set to perform necessary operations.

  In addition, when the electronic album is created after storing the position data and the captured image data, the processing menu 30 is displayed on the display C, and the album creation button 31 on the screen is operated ( # 02 step yes).

  After this operation, the process of generating the link data is executed as shown in the flowchart of FIG. That is, the timing data acquisition unit of the link processing unit 15 extracts the timing data stored in the hard disk HD, and the imaging date acquisition unit of the link processing unit 15 captures from the Exif data attached to each captured image data. Extract date and time data. Next, the link generation unit of the link processing unit 15 generates link data that associates a plurality of timing data with a plurality of shooting date and time data that match and those that approximate each other (steps # 201 and # 202). . The process in step # 202 corresponds to the process in the automatic link mode. After the link data is generated in this way, the route 110 is displayed on the display C as shown in FIG. 6 (details will be described later). The shooting point P (single or plural) of the shot image data is displayed on the route 110 (step # 203).

  When the shooting point P is displayed in this way, the operator determines whether there is an error from the actual shooting position. This error is caused by the time error between the timing data generated by the position acquisition means L and the clock built in the digital camera 105. If there is an error, it is necessary to correct the shooting date / time data. By performing the operation, the shooting date / time data of all the shot image data shot by the corresponding digital camera 105 is corrected at once (steps # 204 to # 206), link data is generated again, and the route 110 is updated. The shooting point P is displayed on the screen for confirmation, and the process ends when the error is resolved. Also, the processes in steps # 205 and # 206 correspond to the process in the correction link mode.

  The processing in step # 202 is realized by displaying the confirmation screen 40 on the display C as shown in FIG. That is, the map data is displayed on the confirmation screen, the route 110 and the photographing point P as the “link position” are displayed on the map data, and the photographing image data associated with the photographing point P by the link data. Is displayed in the display area 41. In this display state, for example, when the operator confirms that the original photographing point Px where the photographed image data was photographed is offset by the distance X as shown in the figure, it is displayed on the screen. By operating the time setting slider 42, it is possible to move the shooting point P on the route 110 to match the original shooting point Px, and the shooting date and time for the time corresponding to the amount of movement of the shooting point P. A process of shifting the data and displaying the shift time on the shift time display unit 43 is performed. More specifically, the position data is acquired at relatively short intervals (several times or more per minute), and timing data is also acquired together with the position data. Therefore, even when the shooting date / time data is shifted and an accurate shooting date / time is set, it is possible to easily extract timing data that matches or approximates the accurate shooting date / time. Therefore, it is possible to easily associate photographed image data in which an accurate photographing date and time is set with the position data including the image data, and as a result, the photographed image data can be displayed in association with an appropriate photographing point on the route 110. is there.

  In the drawing, the display form is set so that the display area 41 is displayed in a small size on the map data. For example, the display area 41 is formed to fill the screen, and a window is opened in a part of the display area 41. It is also possible to set the display form so as to display the map data in the form, and in the present invention, the display form and display size of the map data and captured image data displayed on the screen can be arbitrarily set It has become.

  Furthermore, if necessary, the photographed image data can be switched by operating the buttons 41F and 41R below the display area 41, and the photographing point P in a plurality of photographed image data can be confirmed. After this confirmation, by operating the OK button 44, the correction of the shooting date / time data of all the shot image data shot by the corresponding digital camera 105 is completed. In this navigation system, it is also possible to acquire and process captured image data captured by a plurality of digital cameras 105. In this way, when captured image data captured by a plurality of digital cameras 105 is acquired. In this case, the captured image data captured by any digital camera 105 is processed by shifting the captured date and time extracted from the Exif data attached to the captured image data captured by each digital camera 105 for each digital camera 105. With respect to the image data, it is possible to generate accurate link data by correcting the shooting date and time data collectively.

  In the process shown in the flowchart of FIG. 12, the operator confirms the shooting point P and the original shooting point Px on the map in order to eliminate the error. You may set a processing form so that it may input. Incidentally, the link data has a simple data structure recorded by comparing position data (longitude and latitude data) with the file number of the captured image data.

  Next, although the process at the step # 03 is not shown in the drawing, the keyboard is displayed on the display C, the character information is input in such a form that the finger is brought into contact with the keyboard, the title is set, and is stored in advance. A list of music information titles is displayed on the display C, and if necessary, the music information is selected in a form in which a finger touches the music information to be set in the BGM from the list by performing a trial listening. As a result, the selected music is set in the BGM.

  In step # 04, position data, captured image data, link data, and title are stored, and the electronic album is associated with the selected music as described above in the hard disk HD. It is memorized.

  The storage process in step # 300 can be shown as in the flowchart of FIG. That is, a title is stored in a disc-shaped medium Md such as a DVD-R as a storage medium, a plurality of position data (can be understood as route data), map data corresponding to the route data, and photographed image data. Then, link data and music data are stored, and a reproduction program is stored (steps # 301 to # 303).

  When the processing menu 30 is displayed on the display C and the reproduction button 32 is operated in the reproduction mode after the series of processes is completed as described above, a reproduction screen 50 is displayed as shown in FIG. The process shown in the flowchart of FIG. 14 is executed. That is, when the process is started, the title is displayed on the display C, the music is played, the map data is displayed on the display C, the position data is updated along the time axis at the set intervals, and the route is updated. On 110, the vehicle symbol 111 is displayed at a position corresponding to the updated position data (steps # 401 to # 403). Thus, by displaying the vehicle symbol 111 at a position corresponding to the position data updated at the set interval, the vehicle symbol 111 is displayed in a form (simulation form) that moves along the route 110. Become.

  Next, the presence or absence of the associated position data is determined by comparing the position data and the link data. If there is matching link data, the captured image data associated with the position data is displayed in the display area. 51 is executed (steps # 404 to # 406). When displaying captured image data in this way, there are many cases where a plurality of captured image data is captured at the same capturing point. In such a case, all of the captured image data associated with the position data is displayed. Until the display is completed, a process for stopping the update of the position data is performed. The present invention assumes that a symbol indicating the shooting point P is displayed on the route 110 in a dot shape. However, this symbol is not displayed, or the captured image data is displayed on the route 110 in the thumbnail format. It is also conceivable to set the processing mode to display.

  In addition, on this playback screen 50, a control button 52 that realizes control for executing playback, fast forward, and the like is displayed, and an indicator 53 that displays the playback status on the timeline is displayed. For example, fast forward, rewind, and indicator are displayed. When the position data is changed by the operation of 53, the process of setting the changed position data and displaying the photographed image data as described above is continuously performed until this process ends (#). 407, # 408, # 409 steps). The reproduction screen 50 is provided with a counter 54 for displaying the total number of photographed image data and the current display number.

  When the processing menu 30 is displayed on the display C and the playback button 33 is operated in the actual driving mode, the playback screen 60 is displayed as shown in FIG. 8, and the flowchart of FIG. Execute the process. In other words, the map data corresponding to the position data acquired by the position acquisition means L is displayed on the display C, and at the same time, a normal navigation process for displaying the vehicle symbol 111 at the position corresponding to the position data is executed (step # 501). ), The position data acquired by the position acquisition means L at the time of navigation is compared with the link data, and when there is matching or close link data, the captured image data associated with the link data is displayed in the display area. The process is continuously performed until the process of displaying on 61 is completed (steps # 502 to # 505). Even in such processing, it is assumed that the symbol indicating the shooting point P is displayed on the route 110 in the form of dots. However, this symbol is not displayed or the thumbnail 110 is captured on the route 110. It is also conceivable to set the processing mode so as to display image data.

  In addition, when an electronic album is created by storing data on a DVD-R, when the playback program is executed with the DVD-R set in a personal computer, the playback is exactly the same as in the playback mode described above. A screen 50 is displayed on the display of the personal computer. That is, the vehicle symbol 111 is displayed in the form of moving along the route 110 by updating the position data at the set interval. If there is link data in which the position data and the link data match, the captured image data associated with the position data is displayed in the display area 51. When displaying captured image data in this way, there are many cases where a plurality of captured image data is captured at the same capturing point. In such a case, all of the captured image data associated with the position data is displayed. Until the display is completed, a process for stopping the update of the position data is performed.

  In addition, on this playback screen 50, a control button 52 that realizes control for executing playback, fast forward, and the like is displayed, and an indicator 53 that displays the playback status on the timeline is displayed. For example, fast forward, rewind, and indicator are displayed. When the position data is changed by the operation of 53, the position data after the change is set, and the process of displaying the photographed image data is continuously performed as described above, and the number of the photographed image data displayed Can be grasped by the counter 54.

  As described above, according to the present invention, when the captured image data captured by the digital camera 105 is stored in association with the position data acquired by the car navigation system or the like, the timing data acquired from the position data For example, the position data and the captured image data can be obtained by simply acquiring the shooting date / time data from the Exif data attached to the captured image data, and setting the processing mode so as to associate the timing data and the shooting date / time data via the link data. It is possible to associate a plurality of captured image data with a plurality of position data in a lump without taking time as in the case of associating in a form of displaying and editing on the screen. It will be a thing. In particular, the image data captured by a general digital camera 105 usually includes Exif data. When the position acquisition means L is of the GPS type, time data is acquired when the position is acquired. Because it is necessary, it is easy to store this position data in the form of accompanying timing data, and it is relatively easy to compare each time data and associate the matching or approximated data with each other. The association process can be performed simply by performing the process.

  Further, it is assumed that a relatively large error is included between the time indicated by the clock built in the digital camera 105 and the actual time, but the captured image data captured by the digital camera 105 Since the shooting date / time data extracted from the Exif data includes an error equal to the shooting date / time of all the shot image data, when the error is corrected in the shooting date / time data of the shooting image data to be associated with one position data, the error is corrected. By shifting the shooting date / time data of all the other shot image data shot by the digital camera 105 for a time equal to, the shooting date / time of all the shot image data can be made appropriate and highly accurate association is possible It becomes.

[Second Embodiment]
In addition to the above-described embodiment, the present invention may be configured as follows (in the second embodiment, the same function and number as those of the above embodiment are used for those having the same functions as those of the above embodiment). Attached).

  As shown in FIG. 16, in a sightseeing bus provided with a large number of seats 81 in the vehicle body 80, a display E comprising a liquid crystal display unit 82 and a touch panel unit 83 as shown in FIG. In addition, an input terminal F (an example of an image data acquisition unit) including the semiconductor drive 84 is arranged, and a processing device D is provided via a communication path 85 so that data can be accessed to each input terminal F. The processing device D receives position data from position acquisition means L that acquires position data in real time by receiving a signal from a GPS satellite, displays information on a display C that displays processing information, and a disk drive. 9 is controlled. It is assumed that the operation is performed by a specific person such as a passenger through the display C provided in the processing device D.

  In the input terminal F, when the semiconductor medium Ms storing the photographed image data photographed by the digital camera is set in the semiconductor drive 84, the same as described in the flowchart of FIG. 11 in the first embodiment. The display E is requested to select what should be stored with the selection screen displayed, and the captured image data selected by the operator (passenger) is transmitted to the processing device D via the communication path 85 and stored. A processing form is set. Further, in the processing device D, when storing the captured image data, the terminal F is identified, information on the manufacturer name and model of the digital camera included in the Exif data of the captured image data, and the captured image data file The digital camera is specified from the file number attached to the, and the captured image data captured by the digital camera is stored for each group in an identifiable format.

  When the captured image data is stored in this way, the timing data indicating the timing at which the position data is acquired and the captured date / time data included in the Exif data match each other, and the approximated data are associated with each other by link data. Processing is performed. In the second embodiment, the processing is performed so that the operator corrects the shooting date / time data extracted from the Exif data, and the crew member corrects the shooting date / time for each group by checking the contents of the shot image data. The form may be set.

  The configuration of the processing device D is not fundamentally different from the configuration described in the above embodiment, but the basic processing mode when creating an electronic album is also shown in the flowchart of FIG. 13 in the first embodiment. It is not different from the processing shown. In addition, this system assumes a process of storing data in a storage medium such as a DVD-R to create and store an electronic album and handing the storage medium to each passenger when the trip is completed. In the second embodiment, the storage medium storing the electronic album created in this way is set in a personal computer, and the playback program playback mode is slightly different from the previous embodiment.

  That is, as shown in the flowchart of FIG. 18, when the process is started, the playback screen 50 shown in FIG. 7 is displayed on the display, the title is displayed on this screen, music is played, and the selection screen is displayed on the display. Then, a part of the photographed image data photographed for each digital camera is displayed on this screen to obtain a selection (Steps # 601 and # 602). The process for obtaining the selection is for selecting a process for displaying only a group of photographed image data photographed by the user and a process for displaying all photographed image data (all groups).

  After the group is set in this way, the map data is displayed on the display, the position data is updated at the set interval, and the vehicle symbol 11 is displayed on the route 110 at a position corresponding to the updated position data. (Steps # 603 and # 604). Thus, by displaying the vehicle symbol 111 at a position corresponding to the position data updated at the set interval, the vehicle symbol 111 is displayed in a form that moves along the route 110.

  Next, the presence or absence of the associated position data is determined by comparing the position data and the link data. If there is matching link data, the captured image data associated with the position data is displayed in the display area. 51 is executed (steps # 605 to # 607). When displaying captured image data in this way, there are many cases where a plurality of captured image data is captured at the same capturing point. In such a case, all of the captured image data associated with the position data is displayed. Until the display is completed, a process for stopping the update of the position data is performed. The present invention assumes that a symbol indicating the shooting point P is displayed on the route 110 in a dot shape. However, this symbol is not displayed, or the captured image data is displayed on the route 110 in the thumbnail format. It is also conceivable to set the processing mode to display.

  In addition, on this playback screen 50, a control button 52 that realizes control for executing playback, fast forward, and the like is displayed, and an indicator 53 that displays the playback status on the timeline is displayed. For example, fast forward, rewind, and indicator are displayed. When the position data is changed by the operation of 53, the process of setting the changed position data and displaying the photographed image data as described above is continuously performed until this process ends (#). 608, # 609, # 610 steps). The reproduction screen 50 is provided with a counter 54 for displaying the total number of photographed image data and the current display number.

  As described above, in another embodiment, when a large number of passengers take a landscape or a snapshot using the digital camera 105 at the same sightseeing spot, such as when traveling on a sightseeing bus, different digital cameras are used. It is possible to automatically store the captured image data captured at the same time in association with the same shooting point (position data) even if it was captured at By storing the image data in a storage medium such as a DVD-R and handing it to each passenger, the passenger can watch the electronic album by setting it on a personal computer at home. It is also possible to view the photographed image data or to view only the photographed image data photographed by a specific person.

[Another embodiment]
The present invention may be configured as follows in addition to the embodiment described above.

The photographed image data for which the photographing date and time can be accurately grasped is displayed, the photographing date and time is input in the date and time input unit 122 formed at the bottom of the display unit 121, and the change confirmation button 123 is operated after this input. It is also possible to configure the interface so that the shooting date and time can be changed. In such a configuration, the difference between the shooting date / time data of the Exif data of the shot image data displayed on the display unit 121 and the changed shooting date / time data is regarded as a shift time, and the shot image data is shot. The shooting date and time data of a plurality of shot image data can be collectively set to an appropriate shooting time by shifting similarly to the shooting time of other shot image data shot by the digital camera.

(B) When a shooting point P that has been visited once is visited again and a photograph is taken with the digital camera 105, the photographed image data is stored in a form to be added to the already set shooting point. It is also possible to set the processing mode so as to store the captured image data when the previous visit is made with respect to the shooting point P on the route when the visit is made again. When such processing is performed, the processing mode when the link processing unit 15 performs association may be changed, and when the captured image data is reproduced, the past captured image data, the subsequent captured image data, Can be displayed and viewed in a combined form.

(C) When the captured image data is displayed on the display C, a display form with the map data as the background has been adopted. Instead, the captured image data is displayed on the entire screen of the display C, and the captured image data is displayed. It is also possible to set the display form so that the map data is displayed in a part of the image data.
