The theme name becomes a search condition when searching for images later.
[0016]
Next, the operation of this embodiment will be described. Each terminal functions as an image data registration terminal and an image data reproduction terminal, but here, for convenience of explanation, the following explanation is given assuming that the terminal 111 is connected to the server 10 of FIG. .
[0017]
When the terminal 111 is connected to the server 10, the control unit 11 of the server 10 detects connection (access) from the terminal 111 via the input control unit 12 and controls the terminal 111 according to the main program 14. The operation is roughly divided into an image data registration operation and a reproduction operation. Hereinafter, these operations will be described in detail.
[0018]
FIG. 5 is a flowchart showing an image data registration operation between the server and the terminal. In the following description, the operations of the control unit 11, the input / output control unit 12, and the output control unit 13 of the server 10 are collectively referred to as the server 10.
First, in step Sa <b> 1, the server 10 displays a screen prompting the user ID and password to be input on the display unit of the terminal 111, so that the user inputs the ID and password from the terminal 111, and Send. In step Sb1, the server 10 searches the user database 171 of the administrator database 17 and checks the registered user ID and user password and the input ID and password. If the input ID and password are correct, the process proceeds to one of the following steps. When newly registering image data and position data, the process proceeds to step Sa2, and when already registered, the process proceeds to step Sa3.
[0019]
In step Sa <b> 2, the user selects an image data file and a position data file to be registered from the terminal 111 and transmits them to the server 10. Here, it is assumed that the terminal 111 has previously fetched image data from a digital camera or the like, and position data from a position specifying device such as a GPS into an internal storage unit.
[0020]
In step Sb2, the server 10 receives the image data and the position data from the terminal 111 and registers them in the user database 16. At this time, the server 10 compares the data generation times of the transmitted image data and position data, and performs link calculation between the image data and position data. By performing this link calculation, information as to which image data was captured where, that is, the latitude and longitude of the image data capturing point are calculated. Specifically, in step Sb3, the image data is expanded in the image data table 161, and the position data is expanded in the position data table 162. In step Sb4, the server 10 (control unit 11) compares the shooting date / time of the image data table 161 with the position data acquisition date / time of the position data table 162, identifies the position where the image data was shot, and sets the image data table. The position data ID 161 is determined, and the image data table 161 is updated. Further, at the stage when the image data is transmitted to the server 10, the setting is made such that the entire disclosure range of the image data table 161 is not disclosed to the outside. This setting prevents other users from searching and browsing images, so that registered images are not immediately released to the outside and user privacy is not infringed.
[0021]
After step Sa3, the user (registrant) browses the image data already registered in the user database 16 of the server 10, creates recording data such as a title and a comment for the image, and discloses the data. Work to select the range.
[0022]
First, in step Sa <b> 3, the user inputs a date when action recording is performed from the terminal 111, that is, a date when image data and position data are recorded, and transmits the date to the server 10.
[0023]
In the server 10, the corresponding data is searched from the user database 16 in step Sb5 from the data transmitted from the terminal 111. Next, in step Sb6, the center position and scale of the map image to be displayed on the display unit of the terminal 111 are calculated. At this time, the map image is selected from the map database 15 so as to display all the position data. In step Sb 7, position data, image thumbnails (reduced image data), map data, and a program for displaying the data are transmitted to the terminal 111.
[0024]
The terminal 111 receives the data and displays the position data and the thumbnail of the image on the display unit. A display example at this time is shown in FIG. These displays are displayed by a known browser function based on the program transmitted from the server 10.
[0025]
First, in step Sa4, position data and thumbnails of images are displayed on the entire data display screen A1 in FIG. 6 so that the entire data can be viewed. More specifically, the position data is plotted on the map image calculated in step Sb6 by the position data display unit of A2, and point information (marker information) indicating the shooting position of the image is also displayed. The thumbnails of the images are displayed in chronological order by the A3 thumbnail display section. The thumbnail of the image can be freely selected by an input means such as a mouse, and the point information on the map can be grasped where the selected image was taken.
[0026]
Next, detailed data is created in step Sa5. When the user (registrant) presses the A4 detail data creation button for the image selected on the A1 overall data display screen, the B1 detail data creation screen in FIG. 6 is displayed. The image data is enlarged and displayed, and the shooting date and time, the photographer's pen name, and the like are displayed below the image data. In the B2 theme selection section, for example, an image theme is selected by pull-down. The theme is set in advance by the administrator, for example, and is selected from items in the theme table 172 of the administrator database 17. A comment about the image is input in the comment input section of B3. Data such as comments is reflected in the recording data table 163 of the user database 16. Next, in step Sa6, the disclosure range selection unit of B4 designates the disclosure range of the image. The disclosure range is selected from the user data table 171 of the administrator database 17. By specifying the disclosure range, a registrant can freely select a private image to be made private, an image to be disclosed only to a specific group, or an image to be disclosed to all users. In step Sa7, when the user (registrant) presses the update button B5, the content input on the detailed data creation screen of B1 from the terminal 111 is updated to the user database 16 in the server 10. The detailed data can be repeatedly created for the number of image data.
[0027]
When there is an administrator in the terminal group, for example, the administrator of the group # 1 in FIG. 1 uses the network for all data in the group # 1 input from the terminal 110 and from the terminals 111, 112,. The image published above can be permitted and the detailed data content can be proofread. By giving the administrator the privilege to set the disclosure range of all data in the group, when users write comments that slander others, the data is kept private and the privacy within the group is protected. can do. In this case, as in steps Sc <b> 1 to Sc <b> 6, the administrator also performs data check, correction, and the like by following the same procedure as other users. It is also possible to prevent data from being disclosed to the outside unless the administrator has checked it.
[0028]
FIG. 7 is a flowchart showing an image data reproduction operation. With reference to FIG. 7, the flow of searching and browsing the data disclosed through image data registration via a communication network will be described.
[0029]
In step Sd1, the server 10 displays a screen prompting the user ID and password to be input on the display unit of the terminal 111, and the user inputs the ID and password from the terminal and transmits them to the server 10. The server 10 searches the user data table 171 of the administrator database 17 and checks the ID and password in step Se1. If the input ID and password are correct, the server 10 then displays a search condition designation screen on the display unit of the terminal 111, and shifts control to search browsing.
[0030]
In Sd2, the user of the terminal 111 specifies a search condition. Search items include, for example, image data shooting date, registrant's pen name, theme name, and the like. The user can obtain desired data by designating and searching these search items. For example, in the case of a school excursion, the manager can specify items such as the environment, food culture, and customs as the theme name, so that the learning effect can be further enhanced. The specified search condition data is transmitted from the terminal 111 to the server 10.
[0031]
In the server 10, the server 10 searches the user database 16 for corresponding data from the transmitted search condition, and searches the map database 15 for corresponding map data. Next, in step Se3, the center position and scale of the map image to be displayed on the display unit of the terminal 111 are calculated. If the data search results include multiple location data from different registrants, the map image will be displayed in the center position of the electronic map so that all location data of the registrant (s) to be noted are displayed. The scale is determined. Next, in step Se <b> 4, position data, image thumbnails, map data, and a program for displaying the data are transmitted to the terminal 111. If the data search results include multiple location data from different registrants, all location data will be downloaded and displayed for the location data of one registrant of interest, and other location data will be displayed. In order to reduce the display load, it is possible to display by thinning out every few points, and to transmit only the position data to be displayed to the terminal 111.
[0032]
The terminal 111 receives the data and displays the position data and the thumbnail of the image on the display unit. The displayed data is only data that satisfies the disclosure range in the image data table 161 of the user database 16.
[0033]
8 and 9 show display examples. FIG. 8 shows a case where data is displayed focusing on one registrant's data, and FIG. 9 is an example where data of a plurality of registrants are displayed synchronously. 8 and 9 differ depending on the display program downloaded from the server 10. These displays are displayed by a known browser function provided in the terminal 111.
[0034]
First, a case where attention is paid to one person's data in FIG. 8 will be described. In step Sd3, the position data and image thumbnails are displayed on the entire data display screen of C1 in FIG. 8 so that the entire data can be viewed. Specifically, the position data is plotted on the map image calculated in step Se3 by the position data display unit of C2, and point information indicating the shooting position of the image is also displayed. The thumbnails of the images are displayed in time series by the C3 thumbnail display unit. The thumbnail of the image can be freely selected by input means such as a mouse, and the point information on the map can be grasped where the selected image was taken.
[0035]
Next, a case where a plurality of data in FIG. 9 are displayed in synchronization will be described. In step Sd3, the position data of the plurality of registrants and thumbnails of the images are displayed on the entire data display screen E1 in FIG. 9 so that the entire data can be viewed. The position data of the plurality of registrants are plotted on the map image calculated in step Se3 by the position data display unit E2, and point information indicating the shooting position of the image is also displayed. The thumbnails of the images are displayed in parallel for the registrants of interest, and each is displayed in time series by the E3 thumbnail display unit. The thumbnail of the image can be freely selected by input means such as a mouse, and the point information on the map can be grasped where the selected image was taken. In addition, when you select a thumbnail of one image, the thumbnails of other images are also linked according to the shooting time information, so you can easily grasp who, where, and what you were doing at the same time. Can do.
[0036]
Next, in step Sd4, the user requests detailed data. Specifically, when the C4 or E4 display data creation button is pressed for the image selected on the C1 or E1 overall data display screen of FIG. 8 or FIG. 9, information about which image detailed data is desired is displayed. , Transmitted from the terminal 111 to the server 10. The server 10 retrieves appropriate data from the user database 16 and sends it back to the terminal 111 in step Se5. In step Sd5, the detailed data display screen of D1 or F1 is displayed on the display unit of the terminal 111. The image data is displayed in an enlarged manner, and the shooting date and time, the photographer's pen name, comments, and the like are displayed below the image data.
[0037]
