Description

The present invention relates to a server , an electronic device system, and a program.

  There is known an electronic camera capable of recording position information (latitude and longitude information) acquired by a GPS receiver in association with a moving image. In addition, a system that links such a moving image with position information and a map and clearly indicates whether or not a moving image captured at that position exists at an arbitrary position on the map is also known. If there is a moving image shot at a certain position, one frame of the moving image is displayed as a thumbnail at the corresponding position on the map, and when a thumbnail image selection operation is performed, the moving image is reproduced. Furthermore, when there are a plurality of moving images at a specified position on the map, there is one that can easily select a moving image to be reproduced (for example, see Patent Document 1).

An embodiment of the present invention will be described with reference to FIGS.
A moving image playback apparatus (system) described below is capable of playing back a moving image related to an area specified by a displayed map, and particularly, a moving image (for example, an automobile, a bicycle, an aircraft, etc.) shot while moving a camera. For example, a movie taken with a camera mounted on the camera or a movie taken while walking) is played back.

Among cameras capable of shooting moving images (such as video cameras and digital still cameras with moving image functions) equipped with a GPS receiver, camera position information (shooting position information) may be embedded in a moving image file every predetermined time. it can. In this apparatus, a line indicating the movement path of the camera is displayed on the map using the position information, and any frame of the moving image is displayed as a thumbnail as an index image in correspondence with the movement path. Then, when the user performs a reproduction operation on the thumbnail image, the moving image is reproduced.
In the following description, a line indicating the moving route of the camera is referred to as “moving image route”, and a moving image corresponding to the moving image route is referred to as “route moving image”.

  As a form of the device (system), the above functions are incorporated in a server on the network, and a user accesses the server from each terminal via the network to post a video or play a posted video on a map. A service to enable this is conceivable. It may be an internet line or a smaller network. For connection to the server, a Web browser may be used, or dedicated application software may be used. Alternatively, the above functions may be provided as application software for use in individual computers without using a network.

Hereinafter, a moving image sharing service for an unspecified number of users will be described in detail as an example.
FIG. 1 is a schematic configuration diagram of this system. Each service user (hereinafter referred to as a user) accesses the server 30 of the service provider from the personal computer (hereinafter referred to as user PC) 10 or a mobile phone via the Internet line 20.

  The server 30 includes a communication unit 31 for performing communication, a map database DB1 and a moving image database DB2 for performing map display, a storage unit 32 for storing various programs, and a CPU 33 for executing the program. doing. A moving image posted by uploading from a user is registered in the moving image database DB2. When a video is posted from the user, the CPU 33 reads various types of video information (shooting information, etc.) embedded in the video file in order to realize search processing described later, and displays the video information and video information. The information obtained by the analysis is stored in the moving image database DB2 in association with the moving image file.

  The user PC 10 includes a PC main body 11, an operation unit 12 such as a mouse and a keyboard, and a display 13 as a display device.

2 to 10 show a processing procedure of a program executed by the CPU 33 of the server 30. FIG.
This program is incorporated in the storage unit 32 of the server 30 in advance, and is intended for a user for the purpose of watching a moving image. When the user accesses the server 30 from the PC 10 using a web browser or the like and performs a predetermined operation, the CPU 33 of the server 30 executes this program. It is assumed that a plurality of moving images uploaded by a user as a contributor are already stored in the moving image database DB2 of the storage unit 32.

  In step S1 of FIG. 2, map information is acquired from the map database DB1, and in step S2, a map screen (initial screen) is displayed on the display 13 of the user PC 10 based on the acquired map information.

FIG. 11 shows an example of the map screen displayed on the display 13. On the map screen, a map display unit 41 is arranged in the center, and an index selection unit 42, a search unit 43, a moving image reproduction operation unit 44, a display condition input unit 45, and the like are arranged as user operation units around the map display unit 41. In the initial state, for example, a wide area map including the entire region of Japan is displayed on the map display unit 41. In the map display unit 41, the user can freely change the scale of the map by operating the mouse or the like, and can freely change the display range by dragging the map with the mouse.
In addition, you may enable it for each user to set the map range displayed on an initial screen.

After displaying the initial screen, the CPU 33 waits for any user operation in a loop of steps S3 to S8, and terminates the process when the end operation is confirmed in step S3. When the operation for changing the scale or display range (map operation) is confirmed in step S4, the scale or display range is changed in step S9 accordingly (map screen change). In step S10, the moving image database DB2 is searched, and if there is a route moving image file corresponding to the current display map range, the moving image route for the moving image is displayed on the map. The moving image route is created and displayed by reading shooting position information embedded at a predetermined time period from a moving image file and connecting points on the map corresponding to each position information from the start to the end of shooting with a line.
It is desirable to display the moving image route only when the scale of the displayed map is a certain level or higher.

FIG. 12 shows an example in which a certain area is displayed on the map display unit 41. On the map, moving image routes R1 to R5 corresponding to five moving images are displayed. In the figure, five moving image routes are shown with different line types, but in practice, it is easy to distinguish them by changing the line color. In addition, when a plurality of moving image routes pass through the same part, the route lines are displayed so as not to overlap each other. In the case of a moving image taken with an in-vehicle camera or the like, the moving image route is a line along the road as shown in the figure, but this is not necessarily the case with aerial shooting.
Note that for moving images shot at one place or moving images with a short moving range, the moving image route is displayed with dots or short lines, and therefore the moving image route may not be visually recognized when index display described later is performed.

Next, index processing will be described.
The index here refers to an image (index image) of any frame extracted from the root moving image. By displaying the index image as a thumbnail corresponding to the moving image route, it is possible to inform the user of the contents of the moving image corresponding to the moving image route.

  In FIG. 12, two index images SN1, SN2: SN3, SN4 for the moving image routes R1, R2 are displayed so as to overlap each route.

  As will be described later, the CPU 33 first estimates a main part (basically a part that the user wants to see or a part that the photographer wants to see) of each moving image, and includes any of the main parts included in the main part. Such a frame image is set as an index image. The estimation of the main part and the extraction of the index image can be performed from various viewpoints, and there may be two or more index images for one moving image route, or none may be displayed.

  From what point of view the index image is created, the index selection unit 42 can be selected by the user. The index selection unit 42 has seven items of “shooting start”, “landmark”, “speed change”, “video change”, “recommendation”, “number of reproductions”, and “user designation”. The user can select one or a plurality of items by checking a check box of each item.

  After displaying the moving image route in step S10, the CPU 33 proceeds to index processing in step S11. In FIG. 3 showing the details of the index processing, it is determined in step S101 whether or not “shooting start” as an index item is selected. If the determination is affirmative, index creation A processing is performed in step S102.

In FIG. 4 showing the details of the index creation A process, the CPU 33 performs the following process on all route videos currently being displayed.
In step S201, it is determined whether or not the shooting start point of the moving image is within the current display map range. If step S201 is affirmed, the process proceeds to step S202, and an image of the shooting start frame of the route moving image is set as an index image. In step S203, the index image is displayed at a position on the map corresponding to the shooting start point of the moving image route. Thereby, the user can easily confirm the contents of the shooting start point and the shooting start frame of each route moving image. If the shooting start point is outside the current display map range, the index is not created and displayed.

  In step S103 of FIG. 3, it is determined whether or not “landmark” is selected. If the determination is affirmative, index creation B processing is performed in step S104.

In FIG. 5 showing the details of the index creation B process, the CPU 33 performs the following process on all route videos currently being displayed.
In step S301, it is determined whether or not a landmark exists within the display map range. If the landmark is affirmed, the landmark position information is acquired in step S302. Information about landmarks may be included in the system as a database, but if not, it may be obtained through a predetermined Web service. For example, there is a project that has a database containing geographical data of the whole world and provides such data through a web service, and the location information (latitude and longitude information) of landmarks is acquired through such a service. Can do.

  Here, in the example of FIG. 12, “Landmark” is selected in the index selection unit 42. Two landmarks of “tower” and “temple” exist in the display map range, and symbol marks MK1 and MK2 corresponding to these landmarks are displayed at respective positions on the map.

  In step S303 in FIG. 5, the route moving image within the display map range is analyzed, a portion where the object as a landmark is reflected is extracted, and the portion is set as a main portion of the moving image. Whether or not the object is reflected can be determined, for example, as follows.

  If the camera that shot the route movie has an electronic compass, the camera can recognize the direction in which the taking lens is facing, and the information can be embedded in the movie file along with the position information of the camera at a predetermined time period. . Similarly, information on the focal length of the taking lens can be embedded in the moving image file. The CPU 33 reads these pieces of information from the moving image file, and based on the lens orientation information, the camera position information, and the target object position information, whether the photographing lens faces the target object at each time point (the target object is reflected). Whether or not) is determined. In addition, the distance between the camera and the object can be determined from the position information, and the focal distance information can be added to the distance to estimate the size of the object.

  Here, even if the lens is directed toward the object, there may be a shielding object between the camera and the object, and the object is not actually reflected. Therefore, if the presence or absence of an object is determined more strictly, whether or not the object is truly reflected by pattern matching after further image analysis is performed on the frame in which the object is determined to be reflected by the above method. It may be determined whether or not, and only the frame determined to be reflected may be extracted. The landmark image that is the basis of pattern matching may be stored in the server 30 in advance, or may be obtained from an external Web service or the like. In addition, for a moving image that does not have information indicating the direction of the photographic lens, it may be determined from the beginning whether or not a landmark is reflected only by pattern matching.

In step S304, the CPU 33 sets, as a main part of the moving image, a portion in which frames determined to show the object are continuous. Next, in step S305, an image of any frame is extracted from the main part as an index image (details will be described later). In step S306, the extracted index image is displayed at a corresponding position on the corresponding moving image route. The corresponding position is a position on the map corresponding to a point where the index image is obtained at the time of shooting, and can be recognized from shooting position information embedded in the moving image.
It should be noted that the index image for the “landmark” is not extracted and displayed for the route moving image in which the landmark is not shown.

Next, an index image extraction and display method will be described.
FIG. 13 shows an example in which the images of the top frames of the main portions M11 and M12 of the moving image routes R11 and R12 are extracted as index images SN11 and SN12. That is, the frame when the camera starts to capture the landmark during movement becomes the index images SN11 and SN12, and is displayed at the head position of the main parts M11 and M12 on the map.

  Here, as described above, each moving image route is displayed with a different color, but in each moving image route, a portion corresponding to a main portion (a portion where a landmark is reflected) is highlighted. , And easily distinguishable from non-major parts (parts where no landmarks are shown). As a highlighting method, for example, a method of changing the color of the line between the main part and the non-main part, displaying the main part with a thick line, and displaying the main part with a blinking line can be considered. In FIG. 13, the dark part represents the main part.

  Also, when many video routes are displayed on the map, the index display becomes complicated, but by enclosing each index image with a rectangular frame of the same color as the corresponding video route (main part), the video route and index are displayed. The correspondence with the image can be easily determined visually. These measures can be similarly applied to index items other than “Landmark”.

  Furthermore, in order to eliminate the complexity of the screen, the user may be able to limit the number of displayed videos. In this example, by inputting the display condition and the maximum display number to the display condition input unit 45, the number of moving images (moving image route and index image) exceeding the input value is not displayed. As the display condition, in addition to “Sequential shooting date / time”, “Sequential shooting date / time”, “Sorted by number of views”, “Newest posting date / time”, “Posted oldest date”, etc. Exists as. Note that the display number limitation may be performed individually for the root moving image and the non-root moving image described later.

  In the example shown in FIG. 14, the index image SN21 is displayed in the middle of the main part M21 of the moving image route R21. This display position is the position closest to the landmark in the main portion M21 (the distance between the shooting position and the landmark position is the shortest), and the index image SN21 is also an image of the frame acquired at the position. . Note that the index image and its display position do not necessarily match. For example, an image of a frame obtained at a position closest to a landmark may be displayed as an index image at a position corresponding to the head of the main part.

  FIG. 15 shows an example in which a plurality of index images are displayed in the main part for the moving image route R21 similar to FIG. For example, it is conceivable to extract a plurality of frame images for each predetermined time or predetermined moving distance as index images in the main part and display each image at a corresponding position. As described above, when a plurality of index images exist in a single moving image route, it is desirable to display the plurality of index images so that they are images corresponding to the same moving image route. Conversely, when there are a plurality of moving image routes for the same movement route, it is desirable to display the index images of different moving image routes so as not to overlap each other. In addition, if the index images are displayed in an overlapping manner, the entire index image below cannot be visually recognized. For example, when the mouse pointer is moved to the overlapping index images, multiple overlapping videos are displayed side by side so that they do not overlap. It may be.

  FIG. 16 also shows an example in which a plurality of index images are displayed. In this example, the direction of the index image on the map plane is changed according to the lens orientation information described above. According to this, it is possible to know what the photographer photographed by looking at the index image.

  Basically, any frame image of the main part may be used as the index image. For example, an index image may be extracted at random from the main part.

  Although details will be described later, when the user performs a reproduction operation on the displayed index image, the main part of the moving image is reproduced. Therefore, if a user who wants to see a moving image of a landmark selects “landmark” by the index selection unit 42, the user can not only find a moving image showing the landmark immediately, but also the landmark of the moving image is displayed. You can see the part immediately.

  Next, when it is determined in step S105 in FIG. 3 that “speed change” is selected, the CPU 33 performs index creation C processing in step S106. In FIG. 6 showing the details of the index creation C process, the CPU 33 performs the following process on all route moving images that are currently displayed.

  In step S401, the moving speed of the camera when shooting the route moving image is obtained. For example, when shooting a route movie with a camera, if you set the position information and date and time information to be embedded in a movie file as a set periodically, the camera movement speed in that movie can be read by reading that information Can be requested. Here, the moving image is divided into several parts every predetermined time, and the moving average speed is obtained for each part. The user may be able to specify the part time.

  In step S402, a change in the moving average speed is analyzed, and a main part of the route moving image is estimated. For example, if a place where the moving average speed is reduced by a predetermined value or more is confirmed, it can be estimated that the photographer has relaxed the moving speed by paying attention to some object. Therefore, a portion of the moving image from when the moving average speed decreases by a predetermined value or more to a time when the moving average speed increases again by a predetermined value or more (a portion estimated to show the object that the photographer has noticed) is determined as the main portion. Or you may judge from the location from which the moving average speed fell more than predetermined value to the last as a main part. In step S403, an index image is extracted from the main part, and in step S404, the image is displayed at a corresponding position. For example, a frame image (a first frame image of the main part) where the moving average speed has decreased by a predetermined value or more may be used as the index image.

  If it is determined in step S107 in FIG. 3 that “video change” has been selected, the CPU 33 performs index creation D processing in step S108. In FIG. 7 showing the details of the index creation D process, the CPU 33 performs the following process on all route moving images that are currently displayed.

  In step S501, the data rate of the moving image is analyzed, and in step S502, the main part is estimated based on the result. Here, in the case of a moving image encoded at a variable data rate (bit rate), the data rate is high in a portion where movement is intense, and the data rate is low in a portion where there is no movement. In the case of moving image shooting while moving, the data rate is high in a scene where the camera is pointed in a certain direction because the change in video is severe, whereas the data rate is low in a scene in which a certain object is followed. Therefore, the data rate of the moving image is analyzed, and a portion where the data rate is next increased by a predetermined value or higher is determined as a main portion from a portion where the data rate is decreased by a predetermined value or more. Alternatively, it may be determined that the main part is from the point where the data rate has decreased by a predetermined value or more to the end.

  In step S503, an index image is extracted from the main part, and in step S504, the image is displayed at a corresponding position. For example, the top frame image of the main part may be used as the index image.

  It should be noted that index images relating to “video changes” are not extracted and displayed for moving images that have no significant change in data rate.

  If it is determined in step S109 in FIG. 3 that “recommendation” is selected, the CPU 33 performs index creation E processing in step S110. In FIG. 8 showing the details of the index creation E process, the CPU 33 performs the following process on all route moving images that are currently displayed.

  In step S601, it is determined whether or not there is a recommended portion for the route moving image. The recommended part is set by a video contributor (mostly a photographer). For example, the recommended part is a part that is particularly desired to be shown, and information indicating the beginning and end of the part can be embedded in the video file. The CPU 33 determines the presence / absence of such information, and if it exists, the recommended part is set as the main part in step S602, and if it does not exist, the process directly returns.

  In step S603, an index image is extracted from the main part, and in step S604, the image is displayed at a corresponding position. For example, the top frame image of the main part may be used as the index image.

  If it is determined in step S111 in FIG. 3 that “number of times of reproduction” has been selected, the CPU 33 performs index creation F processing in step S112. In FIG. 9 showing the details of the index creation F process, the CPU 33 performs the following process on all route moving images that are currently displayed.

  In step S701, an area with the largest number of reproductions is extracted from each moving image. In order to realize this, the CPU 33 divides each registered moving image into several areas every predetermined time, and always performs a process of counting the number of reproductions of each area. At that time, the number of times of reproduction is counted up only for an area reproduced continuously for a predetermined time (for example, 10 seconds) or more. If the playback time is less than the predetermined time, it is determined that the video in that area is not particularly interesting to the user, and no count-up is performed. The area extracted in step S701 may be one area where the number of times of reproduction is the largest among the individual moving images, or may be all areas where the number of times of reproduction is equal to or greater than a predetermined number.

  In step S702, the area extracted in step S701 is set as the main area. In step S703, an index image is extracted from the main part, and in step S704, the image is displayed at a corresponding position. For example, the top frame image of the main part may be used as the index image.

  If it is determined in step S113 in FIG. 3 that “user designation” has been selected, the CPU 33 performs index creation G processing in step S114. In FIG. 10 showing the details of the index creation G process, the CPU 33 performs the following process on all route moving images that are currently displayed.

In step S801, it is determined whether or not there is a range designation by the user (the user as a viewer, not the user as the video poster) for the root video. Details of the range specification will be described later. If there is no range specification, the process returns. If there is a range specification, the specified range is set as the main part in step S802. In step S803, an index image is extracted from the main part, and in step S804, the image is displayed at a corresponding position. For example, the top frame image of the main part may be used as the index image. Alternatively, the user may select an index image from the main part.
It should be noted that display / non-display of the index image may be individually switched by an operation by the user.

  When the above index processing (step S11 in FIG. 2) ends, the CPU 33 returns to step S3 and waits for the next operation. When the index item selection operation is confirmed in step S5, the process proceeds to step S12. The index item selection operation is an operation in which the user checks or unchecks the check box of the index selection unit 42. If a check is entered, an index creation process corresponding to the item (any one of the processes A to F in FIG. 3) is performed. If a check is removed, the index image display corresponding to the item is canceled. To do.

  Here, when a user as a video viewer finds a favorite part by watching the root video, the user can specify a range by specifying the first frame and the last frame of the part. When the CPU 33 confirms the range designation operation by the user in step S6, the CPU 33 stores the range designation information in association with the moving image as information unique to each user. For example, by storing the range designation information in the storage unit of the user PC 10 in which the range designation operation has been performed, correspondence with each user can be achieved. The stored range designation information is retained unless a range designation cancellation operation is performed by the user. In the determination process of step S801 described above, the CPU 33 reads range designation information from the storage unit of the user PC 10, and determines whether or not a range is designated for each moving image based on the result. In step S14, the above-described index creation G process (FIG. 10) is performed in order to reflect the range designation operation on the display.

  Although the above has described a moving image in which position information is embedded, the present system can also handle a moving image file that does not have position information, for example, a moving image file shot by a camera that does not have a GPS receiver. However, since the moving image route cannot be created without the position information, it is necessary to acquire an index image separately from the above-described route moving image. Hereinafter, a moving image without position information is referred to as a non-root moving image.

  When posting a non-root video, the contributor instructs the main part of the video in advance and inputs a keyword. These main parts and keywords are associated with the moving image file and stored in the moving image database DB2.

  When the map is displayed, the CPU 33 searches the video database DB2 for a non-route video associated with a place name included in the display map range, a landmark name, a station name, and other keywords matching the keyword, and is found. If it is, the frame extracted from the main part of the moving image is displayed as an index image. For example, the top frame image of the main part may be used as the index image. Alternatively, the poster may be allowed to specify a frame to be used as an index image. In the example of FIG. 12, index images SN5 and SN6 of the non-root moving image searched as described above are displayed at the lower left of the map display unit 41.

Next, the search will be described.
The search is made for the purpose of quickly searching for moving pictures such as landmarks of interest or narrowing down the display when there are too many moving pictures to be displayed. The search operation is performed by the user specifying any search condition (s) in the search operation unit 43 and clicking the search button at the bottom. When the CPU 33 confirms the search operation in step S7 of FIG. 2, in step S15, the CPU 33 selects a video that satisfies the specified search condition from among the videos (route video and non-root video) that can be displayed on the map display. A search is made from the moving image database DB2, and those moving images are set as display targets. In step S16, the search result, that is, the moving image route and index image of the display target moving image are displayed. The index image acquisition method is as described above.

Search operations include the following.
(1) Keyword input: The user inputs a name such as a landmark in the upper text box. In this case, CPU33 extracts a moving image from moving image database DB2 based on the keyword, and displays a moving image route and an index image. When the keyword matches the landmark name, the CPU 33 automatically turns on the “landmark” and “user designation” checks in the index selection unit 42 and turns off the other checks, and performs index creation B processing and index creation G. Process. At this time, it is desirable to display the index image set to non-display.
(2) Date and time designation: The user inputs the first date and the last date and time in the designated range. In this case, the CPU 33 searches the moving image database DB2 for a moving image having a date within the specified range. Alternatively, the year, month, season (spring / summer / autumn / winter), public holidays (spring equinox day, sea day, etc.), time, etc. may be designated to perform the search.
(3) Weather designation: The user designates weather conditions (sunny, rain, etc.) at the time of shooting. In this case, the CPU 33 searches for moving images shot under designated weather conditions. For example, weather conditions at the time of moving image shooting can be acquired from an external weather data providing service based on the shooting date and time and shooting position obtained from a moving image file.
(4) Vehicle designation: Select and designate a vehicle used as a moving means during photographing. Cars, bicycles, walking, etc. exist as options. The moving means can be acquired by the photographer embedding the information in the moving image file. CPU33 searches the moving image image | photographed using the vehicle based on the acquired vehicle information.
(5) Selection of range: The user specifies a position or range on the display map range. One point designation by clicking and range designation by dragging can be selected. In this case, the CPU 33 searches for a moving image whose designated position or range has moved.
When two or more items are designated among the above (1) to (5), the AND search is performed.

  FIG. 17 and FIG. 18 show examples of results displayed when a search is performed. FIG. 17 shows the name of the tower “Tower” as a keyword, and FIG. 18 similarly shows the name of a “temple”. It is. In both cases, the shooting date range is specified. In FIG. 17, a plurality of route moving images including the main part showing the “tower” are extracted by the search, and the moving image route and the index image are displayed. As described above, the main part of each moving image route is a part where the “tower” is continuously shown, and the index image is an image of a frame extracted from the main part. The same applies to FIG.

  As a search condition other than the above, the moving speed at the time of shooting may be designated. For example, ** Km / h to @@ Km / h are specified. This speed may be an average speed or a maximum speed. ** A designation method such as Km / h or more (or less) may be used. The user may be allowed to select a designation method. In any case, the CPU 33 searches for a moving image whose moving speed is within a specified speed range as a display target moving image. The moving speed can be acquired by the method described in step S401 in FIG. The altitude of the shooting location may be designated. The altitude is included in the GPS information. For example, when an event name such as “total solar eclipse” is input, the position and date / time are automatically set, and a search may be performed based on the position and date / time.

  The “automatically change region” check box in the search unit operation unit 43 is for the user to instruct whether or not to change the display map range in accordance with the input keyword. When the check is on, the map is displayed so that the target object (landmark, etc.) corresponding to the input keyword is positioned at the center of the map, and the video routes and index images of all display target videos are displayed. The CPU 33 automatically changes the scroll and the scale ratio. If the check is off, no automatic change is made.

Next, the reproduction of moving images will be described.
When the CPU 33 confirms the reproduction-related operation of the moving image in step S8 of FIG. 2, the CPU 33 performs a reproduction process corresponding to the operation in step S17. The reproduction related operation refers to an operation of each button of the moving image reproduction operation unit 44 (FIG. 12).

  For example, when the user selects an index image of a moving image (root moving image, non-root moving image) to be reproduced by clicking, and clicks the reproduction button 44a, the CPU 33 selects the main part corresponding to the index image from the moving image. Playback within the rectangular frame where the index image was displayed. When the playback button 44a is operated without selecting an index image, the moving images displayed with the index display may be sequentially played back one by one. The playback order is not limited, but the display position of the index image may be played back in order from the moving image close to the center of the map.

  By double-clicking the video route on the map with the mouse or dragging a line along the video route without using the playback button 44a, the main part of the video corresponding to the video route is played back. It may be. At that time, the moving image may be played back in the reverse direction by dragging in the direction opposite to the moving direction at the time of shooting.

At the time of moving image reproduction, the CPU 33 moves the rectangular frame of the route moving image on the moving image route so that the shooting position always matches the corresponding position on the map. This operation is performed by sequentially calculating the position of the rectangular frame based on the position information and time information embedded in the moving image file at a predetermined period, the scale of the map, and the like. As a result, the user can appreciate the moving image while checking at which position the current image is taken.
Note that the rectangular frame of a moving image without a route does not move.

  When the playback button 44a is clicked during playback of the moving image, the moving image is interrupted and the rectangular frame is also stopped. Further, when the all playback button 44b is operated, the main part of all the displayed route moving images is played back simultaneously. With other button operations, you can fast-forward / rewind the movie and cue the main part.

  When the mouse cursor is superimposed on the index image, the corresponding moving image route may be highlighted and information related to the moving image may be displayed. The displayed information can be “reproduction time”, “movement distance”, “average movement speed”, and the like.

  The case where the main part of the moving image is reproduced has been described above, but the moving image may be reproduced including the non-main part.
