(B) Outline of Operation of Embodiment Next, an outline of operation of the present embodiment will be described. FIG. 3 is a diagram for explaining an outline of the operation of the present embodiment. As shown in this figure, in the present embodiment, when a plurality of images included in the image data 32b are reproduced by a slide show, a map including an imaging location that is the location where the image was captured is displayed.
The map includes a plurality of icons 70 indicating imaging locations and a track 53 connecting the imaging locations.
A track bar 50 indicating the playback position of the image is displayed by a slider 54 that moves upward. Icons 51 and 52 are displayed at the start point and end point of the track 53, respectively.

4 and 5 are examples showing the types of maps displayed on the display unit 18. As shown in FIG. 4, the map data 32a has a plurality of maps (three types of maps in the example of FIG. 4) having different scales. FIG. 5 is a diagram showing the relationship between the icon 70 and the scale of the map. FIG.
Shows a scale map corresponding to “S01” shown in FIG. 4, and FIG. 5 (B) and FIG.
C) shows a scale map corresponding to “S03” shown in FIG. Here, FIG. 5 (B)
FIG. 5A is a map corresponding to the area within the dashed line, and FIG. 5C is the map corresponding to the area within the broken line in FIG. In the present embodiment, when the number of captured images per unit area in the vicinity of the imaging position of the displayed image is small during slide show playback, a small-scale map (for example, S01) is displayed, and the number of captured images is large. A map with a large scale (for example, S03) is automatically selected and displayed. Specifically, in the case of displaying an image with the icon 70 located on the left side of FIG. 5A as an imaging location, as shown in FIG. 5B, other images captured around the imaging location are as follows. Since there is no icon (the number of icons 70 is one in total), the wide area map shown in FIG. 5A is displayed. On the other hand, when displaying an image with the icon 70 located on the right side of FIG. 5A as the imaging location, there are four other images captured around the imaging location as shown in FIG. 5C. Yes (a total of five icons 70)
Therefore, the detailed map shown in FIG. 5C is displayed. In this way, when displaying an area where the number of captured images is large, it can be estimated that the area is an area of high interest by the user, so by displaying a detailed map, Detailed information on can be obtained. In addition, when the number of captured images is small, it is determined that the area is of low interest, so that a wide area map that can be viewed from the whole is displayed without displaying a detailed map.
In the wide area map as shown in FIG. 5A, a plurality of adjacent icons 70 are displayed on behalf of about one icon 70. Thereby, it can prevent that visibility falls by the some icon 70 being superimposed and displayed. By the way, in the example of FIG. 4, three types of maps with different scales are shown, but there may be two types or four or more types.

In the present embodiment, when the slide show is started, a plurality of images are sequentially displayed on the display unit 18 and the slider 54 is moved to a position on the track 53 corresponding to the displayed image. Is done. By referring to the position of the slider 54 and the map, it is possible to know the position where the image is captured. In addition, the user can search and display a desired image by moving the slider 54.

(C) Description of Detailed Operation of Embodiment Next, detailed operation of the embodiment of the present invention will be described. FIG. 6 is a flowchart for explaining an example of processing executed in the embodiment of the present invention. When the processing of this flowchart is started, the following steps are executed. That is, in step S10, the registration processing module 34 displays an initial setting screen (not shown) on the display unit 18 and receives input of initial setting items. Note that, on the initial setting screen, for example, a music file used as BGM (Back Ground Music) can be selected, and an effect (effect) when switching images during slide show reproduction can be selected. As the effect, for example, the currently displayed image is faded out, and a new image is faded in and displayed.

In step S11, the registration processing module 34 determines whether or not to start the process. If the process is started, the process proceeds to step S12. Otherwise, the same process is repeated. For example, when the user operates the input device 19 to give an instruction to start processing, the process proceeds to step S12. In other cases, the same processing is repeated until an instruction is given.
In step S12, a “slide show registration process” described later with reference to FIG. 7 is executed. In the slide show registration process, images to be displayed as a slide show are selected, and a map to be displayed with each image is generated and registered.
In step S13, a “slide show creation process” described later with reference to FIG. 9 is executed. In the slide show creation process, a track bar 50 is added to a map displayed together with images in the slide show.
In step S14, a “slide show execution process” described later with reference to FIG. 10 is executed. In the slide show execution process, the slide show generated in step S12 and step S13 is executed, images are displayed as a slide show, and the slider 54 of the track bar 50 is moved according to the imaging location of the displayed image.

Next, details of the slide show registration process shown in step S12 of FIG. 6 will be described with reference to FIG. When the processing of the flowchart shown in FIG. 7 is started, the following steps are executed. That is, in step S30, the image data input module 31 receives selection of images to be displayed as a slide show. That is, the user connects a digital camera (not shown) to the I / F 16 with a USB (Universal Serial Bus) connection cable or the like and operates the input device 19 to select one image to be displayed as a slide show. Then, the image data input module 31 reads the selected image data from the digital camera and stores it in the storage module 32 as the image data 32b.

In step S31, the registration processing module 34 from the operation information input module 33,
The input of the comment displayed along with each image is received. Note that the information to be input as a comment includes, for example, text information, and a character string indicating the content of each image (for example, “beside xx cedar xx” shown in FIG. 11 described later). Entered.
In step S32, the registration processing module 34 acquires imaging information stored in a header or the like of the image selected in step S30. Information acquired as imaging information at this time includes information such as a file name, imaging date and time, longitude, latitude, and altitude. Here, the file name is a name given to the image data file. The shooting date is
This is information indicating the date and time when the image data was captured. The longitude, latitude, and altitude indicate the longitude, latitude, and altitude of the imaging location where the image was captured.

In step S33, the registration processing module 34 stores the comment input in step S31 in the storage module 32 and the imaging information acquired in step S32.
Register in the table 32c. FIG. 8 is a diagram illustrating an example of the table 32c. In this example, the table 32c includes “reproduction order”, “file name”, “imaging date / time”, “longitude”, “latitude”, “altitude”, “route”, “additional information”, “map scale”, In addition, “slider position” is registered. Here, “reproduction order” indicates the reproduction order of images when a slide show is executed. The “file name” is a name given to the image data file, and is information acquired in step S32. “Imaging date and time” is information indicating the date and time when the image was captured, and is information acquired in step S32. “Longitude”, “latitude”, and “altitude” are information indicating the longitude, latitude, and altitude of the image capturing location, and are information acquired in step S32. “Route” indicates the route to which the image belongs, and this information is generated by the processing of FIG. 9 described later. “Additional information” is stored in step S31.
Indicates the file name of the file that stores the comment entered at. “Map scale” indicates the scale of the map that is displayed when the image is displayed during the slide show. As will be described later, the scale of the displayed map is determined by the number of other images captured in a predetermined area centered on the image capturing location. That is, when the number of other images captured in a predetermined area centered on the imaging location is large, a large-scale detailed map is displayed, and when the number is small, a small-scale wide-area map is displayed. Is done. “Slider position” indicates the position of the slider 54 on the track 53 when the image is displayed during the slide show. That is, when the slide show is executed, the slider 54 moves on the track 53 in synchronization with the reproduction of the image, and “slider position” indicates the display position of the slider 54 when each image is displayed. The “map scale” and “slider position” are obtained by the processing of FIG. 9 described later and stored in the table 32c.

In step S34, the registration processing module 34 adds an icon 70 indicating the imaging location to each scale map. More specifically, the registration processing module 34 performs step S3.
The corresponding point on the map of each scale is specified with reference to the longitude, latitude, and altitude of the imaging information acquired in 2. Then, an icon 70 is added to the specified point.
At this time, if the already added icon 70 exists at a nearby point,
Stop new additions. Specifically, for example, when an existing icon 70 and at least a part of the icon 70 to be newly added overlap, the visibility is lowered when the new icon 70 is added, so that no new icon is added. . By such processing, FIG.
In the case of a map with a large scale as shown in FIG. 5, when the distance between the icons 70 is a predetermined distance or more, a plurality of icons 70 are added. On the other hand, as shown in FIG. 5A, when the distance between the icons 70 is not more than a predetermined distance on a map with a small scale, a plurality of icons are representatively displayed by one icon 70.

In step S35, the registration processing module 34 determines whether or not to repeat the process of adding a new image. If the process is repeated (step S35; Yes), step S30 is performed.
Returning to step 4, the same processing as described above is repeated, and in other cases (step S35; No)
Then, the process proceeds to step S36. For example, when the user operates the input device 19 and gives an instruction to end the selection of an image, the determination is No and the process proceeds to step S36.

In step S36, the registration processing module 34 selects one image to be processed from the table 32c. In step S37, the longitude and latitude indicating the imaging location of the image selected in step S36 are acquired from the table 32c, and a predetermined area centered on the imaging location (for example, a circle having a radius of 100 m centered on the imaging location). The number (density) of images taken in (region) is calculated. Specifically, the file name is “F000” as the processing target.
When the image of “001” is selected, the longitude “E135.15.25” and the latitude “N3” are selected.
All other images captured in the region of radius 100 m centering on “5.11.31” are retrieved from the table 32c. As a result of this search, if three images including the image to be processed are captured in the area, the number is calculated as “3”.

In step S38, the registration processing module 34 determines the scale of the map displayed together with the images during the slide show, based on the number of images obtained in step S37.
Specifically, for example, when there are three types of maps (S01 to S03) as shown in FIG. 4, when the number of images obtained in step S37 is less than "2", the map of S01 is selected. When the number of images is “2” or more and less than “5”, the map of S02 is selected, and when the number of images is “5” or more, the map of S03 is selected. Thus, selecting a map with a large scale when the density is high is considered that a region with a high image density is a region where the user is highly interested. This is because detailed information can be obtained.

In step S39, the registration processing module 34 registers information indicating the type of map selected in step S38 in the table 32c. As a result, “S01”, “S02”, or “S03” is selected and registered in the “map scale” of FIG. 8 for each image.

In step S40, the registration processing module 34 determines whether or not to repeat the process, and determines that the process is to be repeated because the process for all images has not been completed (step S40).
(40; Yes), the process returns to step S36, and the same processing as described above is repeated. Otherwise (step S40; No), the processing ends.
Through the above processing, an image to be displayed in the slide show is selected and the image data 32 is selected.
It is stored in the storage module 32 as b. Further, the image capturing information of the image is stored in the acquired table 32c, and an icon 70 indicating the image capturing location is added to each scale map. Further, the number of images in a predetermined area centered on the imaging location is calculated, the scale of the map displayed together with the images during the slide show is determined, and the table 32c.
Stored in

Next, processing for adding the track bar 50 to the map will be described with reference to FIG.
When the processing of this flowchart is executed, the following steps are executed. That is, in step S60, the creation processing module 35 reads information indicating the longitude and latitude of each image from the table 32c. In subsequent step S61, the creation processing module 35 determines whether or not the reading of the information of all the images to be subjected to the slide show has been completed, and determines that the reading of the information of all the images has been completed (step S61; If yes, the process proceeds to step S62. Otherwise (step S61; No), the process returns to step S60 and the same process is repeated.

In step S62, the creation processing module 35 uses a point indicated by the read information indicating longitude and latitude as a node, and obtains a curve (route) connecting the plurality of nodes by interpolation processing. As the interpolation process, for example, Hermite interpolation, spline interpolation, and other interpolation processes can be used. In addition, for locations where the density of imaging locations is high, representative values of the plurality of imaging locations may be used as nodes.

In step S63, the creation processing module 35 creates the track 53 of the track bar 50 based on the path generated in step S62. More specifically, the creation processing module 35 enlarges or reduces the route generated in step S62 according to the scale of each map, and adds icons 51 and 52 to the start point and the end point. When the track 53 and the icon 70 overlap, the position of the track 53 may be finely adjusted so that they do not overlap.

In step S64, the creation processing module 35 adds the track created in step S63 to each scale map. As a result, a track 53 and icons 51 and 52 as shown in FIG. 3 are added to each map. The map to which the track is added in this way is stored in the storage module 32 as display data 32d.

In step S65, the creation processing module 35 selects an image to be processed from the table 32c. In step S66, the creation processing module 35 acquires the longitude, latitude, and map scale relating to the selected image from the table 32c.
Next, in step S <b> 67, the creation processing module 35 determines the display position of the slider 54 on the track 53 while displaying the target image. More specifically, the creation processing module 35 obtains the distance between the point on the map obtained based on the longitude and latitude and each point of the track 53 and determines the position where the distance is the minimum as the display position of the slider 54. To do. At that time, the scale of the track 53 differs for each map.
Calculation is performed with reference to information indicating “map scale”.
In step S68, the creation processing module 35 registers information indicating the display position of the slider calculated in step S67 in the table 32c as “slider position”. Specifically, in the example of FIG. 8, for example, in the case of the first information, “20, 250” that is coordinate information is stored as the slider position.
In step S69, the creation processing module 35 determines whether or not to repeat the process, and determines that the process is to be repeated because the process for all images has not been completed (step S).
69; Yes), the process returns to step S65, and the same processing as described above is repeated. Otherwise (step S69; No), the processing ends.

With the above processing, the track bar 50 is generated and added to the map, and the display position of the slider 54 on the track 53 when each image is displayed is calculated and registered in the table 32c.

Next, an operation at the time of slide show reproduction will be described with reference to FIG. When the processing of the flowchart shown in FIG. 10 is started, the following steps are executed. That is, in step S90, the execution processing module 36 selects an image to be reproduced as the table 3.
Select from 2c. Specifically, the execution processing module 36 has information indicating the current display position in the table 32c (for example, information indicating “reproduction order” in FIG. 8), and refers to the information from the table 32c. Select an image to play. For example, in the case of the first processing, the file name stored first in the table 32c is “F0000”.
The image “01” is selected.

In step S91, the execution processing module 36 selects a map to be displayed simultaneously with the image. More specifically, the execution processing module 36 acquires the map scale corresponding to the image selected in step S90 from the table 32c. For example, in the case of the first process, “S01” is acquired from the table 32c.

In step S92, the execution processing module 36 maps data corresponding to the map selected in step S91 (data obtained by adding the track bar 50 and the icon 70 to the map).
Is obtained from the display data 32 d stored in the storage module 32 and supplied to the display processing module 37. As a result, the display processing module 37 displays the supplied map data on the display unit 18.

In step S93, the execution processing module 36 acquires the slider position of the target image from the table. Specifically, for example, in the case of the first processing, “20, 250” is acquired from the first in the table.
In subsequent step S94, the execution processing module 36 supplies the slider position acquired in step S93 to the display processing module 37. The display processing module 37 displays the slider 54 on the track 53 based on the supplied slider position.
Through the above processing, as shown in FIG. 11, the map, the track bar 50, and the plurality of icons 70 are displayed in the area 18 a of the display unit 18. In this example, an S-shaped curve is displayed as the track 53, and icons 51 and 52 are displayed at the start point and end point of the curve. Around the track 53, a plurality of icons 70 indicating the imaging location are displayed. Of the plurality of icons 70, the icon (lower left icon) corresponding to the image currently being displayed is highlighted (highlighted). On the track 53, a slider 54 is displayed at a position corresponding to the image being reproduced. The highlight display is to change the display form of the icon 70 from that of the other icons 70. For example, there are methods of blinking display, changing the display color, and changing the display shape. Other methods may be used.

In step S95, the execution processing module 36 executes a process of switching the displayed image to a new image. That is, the execution processing module 36 refers to the table 32c,
A new image is acquired from the image data 32 b and supplied to the display processing module 37. The display processing module 37 switches the currently displayed image to the supplied new image based on the effect (effect) set by the initial setting in step S10 of FIG. Specifically, the currently displayed image is faded out and a new image is faded in. As a result, an image is displayed in the area 18 b of the display unit 18. In the example of FIG. 11, an image in which a person and a plurality of trees are captured is displayed.

In step S96, the execution processing module 36 acquires the file name of the comment corresponding to the image newly displayed in step S95 from the table 32c, reads the file corresponding to the file name from the storage module 32, and displays the display processing module. 37. The display processing module 37 displays the supplied comment on the display unit 18. As a result,
Comments are displayed in the area 18c of the display unit 18 as shown in FIG. In this example,
“In the side of XX cedar of XX” is displayed as a comment.

In step S97, the execution processing module 36 determines whether or not the slider 54 has been operated by the user. If the slider 54 has been operated (step S97; Yes), step S99 is performed.
In other cases (step S97; No), the process proceeds to step S98. More specifically, when the user operates the input device 19 and moves the slider 54 while referring to the information displayed on the display unit 18, the execution processing module 36 displays the slider 5.
It is determined that 4 has been operated, and the process proceeds to step S99. If there is no operation,

As described above, by repeating the processes of steps S90 to S98, images are sequentially displayed on the display unit 18, and a map and a comment are displayed. Further, the map displayed in the area 18 a is selected in accordance with the image density, and a slider 54 is displayed at a corresponding position on the track 53.

FIG. 12 is an example of a screen displayed after FIG. In this example, the area 18b includes
An image different from FIG. 11 is displayed. That is, in this example, an image in which a person and a torii are captured is displayed. In the area 18c, “△△ Shrine's XX with Torii” is displayed as a comment regarding the image displayed in the area 18b. Further, a detailed map having a larger scale than that in the case of FIG. 11 is displayed in the area 18a. In more detail, FIG.
Two icons 70-1 and 70-2 corresponding to the second icon 70 from the left of 1 are displayed, and the icon 70-1 located on the left side of these two icons 70-1 and 70-2.
Is highlighted. Note that these two icons 70-1, 70- in FIG.
In FIG. 11, 2 is displayed as one icon 70 because it is arranged close to each other. The slider 54 is displayed under the highlighted icon 70-1. Furthermore, in FIG. 12, the amount of map information displayed in the area 18a is increased compared to the case of FIG. That is, in the example of FIG. 12, information such as facility names, place names, map symbols, and the like that are not displayed on the map of FIG. 11 is displayed in FIG. 12. Specifically, in FIG. 12, map names corresponding to the place names “Yamayama” and “ΔΔ hot spring” are newly displayed.

FIG. 13 is an example of a screen displayed after FIG. In this example, the area 18b includes
An image different from FIG. 12 is displayed. That is, in this example, an image in which two persons and a torii are captured is displayed. In the area 18c, “Δ △ shrine at xx torii is a couple” is displayed as a comment regarding the image displayed in the area 18b. In the area 18a, a map of the same scale as that in FIG. 12 is displayed, and an icon 70-2 on the right side of the icon 70-1 highlighted in FIG. 12 is highlighted. Also,
A slider 54 is displayed under the highlighted icon 70-2.

FIG. 14 is an example of a screen displayed after FIG. In this example, the area 18b includes
An image different from FIG. 13 is displayed. That is, in this example, an image in which a person and a house are captured is displayed. In the area 18c, “in the old XX residence” is displayed as a comment regarding the image displayed in the area 18b. Further, a detailed map having a larger scale than that in FIG. 13 is displayed in the area 18a. More specifically, six icons 70 corresponding to the three icons 70 displayed close to the right side of the region 18a in FIG. 13 are displayed, and the icon 70 positioned at the bottom of these six icons is displayed. Is highlighted. A slider 54 is displayed on the left side of the highlighted icon 70. Furthermore, in FIG. 14, the information amount of the map displayed in the area 18a is further increased compared to the case of FIG. That is, in the example of FIG. 14, information such as facility names, place names, map symbols, and the like, which are not displayed on the map of FIG. 13, are displayed in FIG. Specifically, in FIG. 14, the facility names “xx monument” and “△△ post office” are newly displayed,
Map symbols corresponding to each are newly displayed. For this reason, the larger the scale, the greater the amount of information displayed on the map. As a result, the user can obtain detailed information around the imaging location with a high degree of interest.

As shown in FIGS. 11 to 14, when the slide show is started, images are sequentially displayed in the area 18b, and comments corresponding to the images are displayed in the area 18c. In the area 18a, a map corresponding to the map scale stored in the table is displayed, and a track bar 50 is displayed. Slider 54 displayed on the track bar 50
Is displayed at a predetermined position on the track 53 near the imaging location. Thereby, the imaging location on a map can be known. Moreover, since it is determined that the degree of attention of the user is high for a place where a plurality of images are captured, a map with a large scale is displayed, and detailed information can be obtained from the map. Further, by displaying a map with a large scale, it is possible to display as many icons 70 as the number of actual images.

If it is determined in step S97 that the slider 54 has been operated, the process proceeds to step S99. In step S99, the execution processing module 36 receives the input device 1.
The operation information input from 9 is acquired via the operation information input module 33, and the position (for example, coordinate value) of the slider 54 after movement is acquired.
In step S100, the execution processing module 36 searches the table 32c for an image corresponding to the slider position acquired in step S99. Specifically, the execution processing module 36 searches the table 32c for the slider position that is closest to the slider position acquired in step S99. Then, the process proceeds to step S90. In step S90, an image corresponding to the image selected in step S100 is selected from the table 32c. The processes after step S91 are the same as those described above.
According to the processing in steps S97, S99, S100, and step S90 and subsequent steps, when the user operates the slider 54 to move it, an image corresponding to the position of the slider 54 after the movement is selected and displayed in the area 18b. In addition, the region 18a and the region 18c include
The corresponding map and comment are displayed. More specifically, in the screen shown in FIG. 13, when the slider 54 is moved to the position of the second icon 70-1 from the left (when returned), it corresponds to the second icon from the left. After the image is selected as a target, FIG.
Will be displayed. If the slider 54 is moved outside the range displayed in the area 18a, a map corresponding to the new area is displayed, and the slider 54 is moved along the track 53 existing on the displayed new map. Can be moved. Note that the scale of the displayed map may be determined based on a map scale associated with the image obtained by obtaining an image corresponding to the position of the slider 54 after the movement. Alternatively, the slider 54
You may make it fix to the reduced scale of the map currently displayed at the time of being operated. Furthermore, you may enable it to change the scale of a map according to a user's operation.

Next, an example of processing executed between step S92 and step S93 in FIG. 10 will be described with reference to FIG. The process of FIG. 15 is a process executed when the “function for displaying map information corresponding to the keyword included in the comment” is turned on in the initial setting shown in step S10 of FIG. . When the processing of the flowchart shown in FIG. 15 is executed, the following steps are executed. That is, the execution processing module 3
6 determines in step S120 whether or not the map displayed in step S92 is a detailed map. If the detailed map is displayed (step S120; Yes), the process proceeds to step S121. In the case (step S120; No), the process is terminated. For example, if “S02” or “S03” shown in FIG. 4 is displayed, the process proceeds to step S121. It should be noted that the process may proceed to step S121 only when “S03” is displayed, or the user may be able to set in what case the process proceeds to step S121.

In step S121, the execution processing module 36 acquires a comment corresponding to the display target image with reference to “additional information” in the table 32c. For example, in the display example of FIG.
The comment “△△ Shrine's XX with Torii” is acquired.
In subsequent step S122, the execution processing module 36 extracts keywords from the comment acquired in step S121, for example, using morphological analysis processing. In the example of FIG. 12, the comment “△△ with shrine XX torii” is used as a keyword “△△ shrine”.
And “XX Torii” are extracted.
In step S123, the execution processing module 36 acquires information corresponding to the keyword acquired in step S122 from the peripheral information data (not shown) stored in the storage module 32 by searching. For example, in this example, as information corresponding to the keyword “△△ shrine”, “△△ shrine main shrine” and “△△ shrine shrine” and information (latitude and longitude) indicating the location thereof are acquired. .
In step S124, the execution processing module 36 displays the search result as the display processing module 3.
7 is supplied. The display processing module 37 displays the supplied information so as to overlap the map displayed in the area 18a. FIG. 16 is a display example of a screen corresponding to the above-described example. FIG.
In the display example, “ΔΔ Shrine Main Hall” and “ΔΔ Shrine Kagura Hall” are displayed on the map displayed in the area 18a. By referring to such a display, the user can refer to information related to the currently displayed image on the map. In the example of FIG.
Although the map symbol and the character string are displayed, for example, image information or text information may be displayed. Specifically, in the example of FIG. 16, △△ displays text information explaining the history of the shrine with a new area, or △△ displays the shrine's main hall image with a new area as well. You may make it.

As described above, according to the embodiment of the present invention, a large-scale detailed map is displayed when the number of captured images in the vicinity of the image capturing location of the displayed image is large, and the number of captured images is small. Displays a map with a small scale, so it is possible to give the user detailed information of the vicinity of the imaging location by displaying a region with a large number of images that the user is likely to be interested in on a detailed map. it can.

Further, in the present embodiment, when a plurality of icons 70 are displayed in an overlapping manner, the plurality of icons 70 are displayed together as one icon 70, so that a wide-area map with a particularly small scale is used. In FIG. 5, it is possible to prevent a plurality of icons 70 from being displayed overlappingly and to reduce visibility.

In the present embodiment, the icon 70 corresponding to the image displayed in the area 18b is highlighted, so that the user can know where the currently displayed image is captured. .

Further, in the present embodiment, when the map displayed in the area 18a is a detailed map with a large scale, the peripheral information indicating the facility or place existing around the imaging location is displayed. For imaging locations where a user's interest is high and a map with a large scale is displayed, information indicating facilities or locations existing in the vicinity can be displayed to provide more detailed information.

In the present embodiment, the larger the scale of the map, the greater the amount of information displayed in the area 18a. Therefore, there are many imaging locations where the user's interest is high and the detailed map is displayed. Visibility can be improved by reducing the amount of information about the imaging location where the wide area map is displayed.

Further, in the above embodiment, in order to simplify the description, information in which the track bar 50 is previously added to the map is held and displayed as necessary.
And the map may be stored as separate data, and these may be superimposed and displayed during display.
In the above embodiment, the track 53 is drawn as a curved line, but may be displayed as a broken line connecting the imaging locations. In that case, when there are a plurality of imaging locations close to each other, a polygonal line is displayed in a zigzag manner between these imaging locations. A broken line may be drawn based on a specific place.

In the above embodiment, three kinds of maps having different scales are used.
Even with different types of maps, four or more types of maps may be used. Alternatively, the map data may be held as vector data, and the map may be drawn based on an arbitrarily designated scale. Moreover, it is not arbitrary and you may make it draw based on the reduced scale selected from several predetermined scales.

In the above embodiment, the icon 70 having the same shape is always used as the icon 70 indicating the imaging location. However, for example, the icon display mode is set according to the number of imaging locations represented by the icon. May be changed. For example, the display size of the icon may be increased or decreased according to the number of representative imaging locations, or a number corresponding to the number of representative imaging locations may be displayed around the icon.

In the above embodiment, only longitude and latitude are used and no altitude is used. However, for example, a three-dimensional map and a track bar may be displayed using altitude information. Good. According to such a display form, it is possible to grasp the situation of the imaging location more accurately by taking into account information related to altitude from the display screen. For example, in the case of an image picked up at the top of a mountain, the slider is located near the peak in the height direction of the track, so that it can be understood that the image was picked up at a high position such as the top of the mountain.

Further, in the above embodiment, peripheral information such as facilities and places existing in the vicinity is searched and displayed from the keywords included in the comments. For example, categories such as facilities and places to be displayed are displayed. It may be selected in advance and peripheral information included in the selected category may be displayed. Alternatively, all information can be displayed without selection.

In the above embodiment, the scale of the map is changed according to the number of images captured in a circular area centered on a predetermined imaging location. However, the map area is not a circular area but a rectangular area. It is also possible. In the above embodiment, the area is fixed.
The area may be changed by the user. In addition to simply referring to the number of captured images, for example, the scale may be determined in consideration of the distance between the imaging location of interest and another imaging location closest to the imaging location. For example, the scale can be increased when the distance to other nearby imaging locations is short, and otherwise the scale can be kept unchanged or the scale can be reduced even when the density is high.
