  However, in methods such as Patent Documents 1 to 4, image data and position information can be stored in association with each other and stored in association with a map, but a large amount of data is displayed in association with a map. In such a case, it is difficult to extract only the data that is necessary. Further, even if a tag can be set for image data and a search can be performed based on the tag, it is necessary to set a detailed tag in order to perform a search with higher accuracy, which is troublesome.

  Therefore, in view of the above problems, the present invention saves image data in association with position information and date / time information, adds a tag that characterizes the image to the user, and further adds a weight suitable for the user environment. It is an object of the present invention to provide a search system, a search method, and the like that take into account user preferences that can easily narrow down necessary image data.

  The present invention provides a system, method, computer program, and server having the following solutions.

(1) A system for retrieving data with location information added thereto,
Mobile communication comprising image data acquisition means, position information acquisition means for acquiring position information and date / time information when the image data acquisition means acquires image data, and tag setting means for setting a tag related to the image data A terminal,
A location data storage server that receives and stores the image data, the location information, the date and time information, and the tag from the mobile communication terminal;
In response to a request from a communication terminal, a content request based on a search condition including at least one of address information or latitude / longitude information, the tag, and the date / time information as position information is transmitted to the position data storage server. A Web server for generating content search results for region information for the user of the communication terminal;
A system comprising:

  In this system, the mobile communication terminal includes image acquisition means such as a camera and position information acquisition means such as GPS. The portable communication terminal associates the position information and date / time information obtained by the position information obtaining unit with the image data obtained by the image obtaining unit (in this specification, “image” includes a still image and a moving image). . For example, the position information of the place where the image is taken and the date / time information at that time are added to the photo data. The mobile communication terminal can add a tag related to the image data. For example, when a picture of a ramen shop is taken, a tag such as “ramen” is added.

  Such image data and its position information, date / time information, and added tag are transmitted to and stored in the position data storage server. However, this tag can be added or changed even after the image data is transmitted to the server. In addition, the Web server storing the content database transmits a content request based on the search condition to the location data storage server in response to a request from the communication terminal, and the content search result is transmitted to the region for the user of the communication terminal. Generate information.

  With such a configuration, it is possible to perform a highly accurate search by combining position information, date and time information, and tags as a search condition for a large amount of image data, and also suit the search user's environment and preferences. The image data can be displayed visually as regional information.

(2) The system according to (1), wherein the position data storage server adds a weight to the stored image data.

  According to such a configuration, weighting data is added in the position data storage server so that the user can easily search the stored image data. This weighted data (for example, realized by an evaluation point described later) is combined with the above-described position information, date / time information, and tag to enable a more accurate search.

(3) The system according to (2), wherein the weighting is obtained by assigning weighting points based on the number of bookmarks or the number of accesses of the image data.

  According to such a configuration, since the weighting described in (2) is specifically determined by the number of bookmarks and the number of accesses to the image data, more popular images are preferentially displayed during search. become.

(4) The weighting is obtained by assigning weighting points to image data created by other users related to the user of the communication terminal according to the degree of the relationship (2) or (3 ) System.

  According to such a configuration, in addition to the weight described in (2) or the weight described in (2), a user related to the searching user (for example, a user registered as a friend) created The image can be set to be higher. As a result, information related to the community to which the user belongs can be displayed more preferentially.

(5) The system according to (2) to (4), wherein the weighting is obtained by assigning a weighting point based on an evaluation point from another user to the creator of the image data.

  According to such a configuration, it is possible to preferentially display an image created by a user who has a high evaluation from other users, that is, a highly reliable user. This is because an image created by a highly evaluated user with the same object is considered to accurately capture the object. For example, when searching for a delicious ramen restaurant in the area, an image from a highly rated user is displayed with priority over other images.

(6) The system according to (1), wherein the Web server associates position information of searched image data with a map and displays a thumbnail image of the image data on the map.

  According to such a configuration, the thumbnail image of the searched image data is visually displayed in association with the position on the map, which is useful for searching and narrowing down image data related to the search target area using the GUI. be able to.

(7) The system according to (1), wherein the Web server searches the image data with reference to a designated search target period and the generation date and time of the image data.

  According to such a configuration, the date and time when image data was created (typically the date and time when a picture was taken) can be added to the search condition. That is, it is possible to obtain the latest regional information or to collect information on the past of the region by preferentially displaying a newer one at the time of creation.

(8) The system according to (6), wherein the association with the map is performed by dividing a map of a region to be displayed into a matrix and displaying the thumbnail image on the matrix.

  According to such a configuration, for example, one thumbnail is displayed on one matrix on the map. In this way, the thumbnail images to be displayed can be made different by changing the size of the matrix. That is, it is possible to dynamically search for an image closer to the region. For example, when the size of the matrix is 1 km square, an image having the highest weight in the matrix (for example, an image of a large-scale store such as a department store) is displayed, but if the size of the matrix is changed to 100 m, another image is displayed. (For example, an image of a smaller store such as a convenience store) can be displayed. That is, it is possible to perform a search in consideration of the size of the target object and the weight in the matrix.

(9) The system according to (1), wherein the request for regional information further includes scale information on a map.

  According to such a configuration, the action / effect described in (8) can be realized more specifically by changing the scale of the map. That is, when the scale is increased, a high-weight image is displayed in a wide matrix in the area, and when the matrix is reduced, more detailed information on small shops can be obtained.

It is possible to provide a search method for image data that can be used.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following description will be given mainly assuming the case of a mobile phone as a mobile communication terminal. However, the mobile communication terminal includes a display device that includes its own position detection means, can be wirelessly connected to a Web server of a service provider, and can display a Web page. Any other portable terminal (PHS, PDA, notebook computer, etc.) may be used.

  FIG. 1 is a diagram showing a system configuration according to a preferred embodiment of the present invention. First, the mobile communication terminal 1 includes position information acquisition means for acquiring its own position. That is, information about its own position is received from the GPS satellite 2 or the base station 3 (such as PHS). If this mobile communication terminal 1 cannot acquire position data (latitude, longitude, altitude, reliability, etc., if possible) alone, a position data acquisition server 6 connected via the public communication network 4 Communicating with and positioning the position of itself. The result of this positioning calculation is obtained and used as its own terminal position data. Alternatively, when the mobile communication terminal 1 can acquire the position data alone, the mobile communication terminal 1 may perform positioning calculation inside the terminal and obtain its own terminal position data. The position information acquisition means can acquire not only the position information of the terminal but also the date and time information when the position information is acquired.

  This system includes a mobile communication terminal 1, a network 5, a Web server 7, a community management server 8, and a location data storage server 9. However, each server may be composed of a single device or a plurality of separate devices, or each server may be composed of a single device.

  In addition, the mobile communication terminal 1 includes image acquisition means for inputting (photographing) image data such as photographs and moving images, like a camera-equipped mobile phone. Furthermore, the image data and the position data of the target object of the image are stored in association with each other and transmitted to the server.

  FIG. 2 is a diagram showing a display flow of image data to be searched. First, in step S11, an address, latitude, and longitude specified by the user are accepted as input data. Next, based on the latitude and longitude, the area to be displayed is specified in step S12. In step S13, whether there is an image that can be displayed in the area to be displayed (whether there is image data of an object considered to be located in the area from the latitude and longitude data attached to the image data). If the determination is NO, the process ends. If YES, first, in step S14, the area to be displayed is divided into a matrix (a mesh area on a grid on the map). However, the size of this matrix may be variable. Next, in step S15, image data having the highest weight (highest point) is extracted from each matrix. This weighting will be described later. In step S16, each matrix is displayed in association with latitude and longitude. For example, the latitude and longitude rulers are displayed in the area around the matrix.

  After this display is performed, in step S17, it is determined whether or not to further narrow down the display data. If there is no need to narrow down (step S17: NO), the process is terminated. If there is a need to narrow down (step S17: YES), the process proceeds to step S18, and in order to narrow down the displayed data, user input of date and time data is accepted as a search target tag and a search target period. Using this user input, the processing of steps S13 to S17 can be repeated to narrow the display data.

  FIG. 3 is a diagram showing a flow for registering the position data of the image data from the mobile communication terminal 1. In this figure, for example, by setting the mobile communication terminal 1 to a mode in which “automatic upload is enabled”, the position data storage server 9 is automatically informed of its own position data periodically or when image data is taken. Can be transmitted. Of course, the position data may be transmitted by an explicit operation of the user without performing such automatic uploading.

  As already described here, when the mobile communication terminal 1 cannot acquire position data alone, it sends a positioning information request (GPS satellite information, neighboring base station information) to the position data acquisition server 6 to acquire position data. The server 6 performs a positioning calculation and returns the positioning result.

  When the mobile communication terminal 1 can acquire position data independently, it performs a positioning calculation by itself and generates terminal position data. The terminal position data obtained in any case is transmitted to the position data storage server 9 together with image data such as photographs taken at the same time, and after the ID of the terminal is specified, the image data associated with the position data is displayed. accumulate.

  FIG. 4 is a diagram showing search of image data and transmission of regional information. First, the position data storage server 9 weights image data stored in the server periodically. Some of these weightings are accumulated and others are dynamically added when a display request is received from the user. That is, the weighting to be accumulated is the number of bookmarks, the number of links, the number of accesses of other users, the user preference (for example, images posted by highly rated users) registered in bookmarks by other users for the image data. Evaluation points are added according to the situation and accumulated in the database. In addition, as a weighting dynamically added when a display request is received from a user, for example, an image posted by a user belonging to his friend or the same community is displayed when the user profile ( Points are dynamically given by referring to the community management server 8 that manages user ID, terminal ID, friend ID, and the like. This dynamic point is not stored in the database. The user evaluation may be given to a user by a plurality of evaluation points depending on the region or the type or tag of the image.

  The communication terminal 11 (which may be the mobile communication terminal 1 but may be another communication terminal) transmits a search request including the latitude / longitude, scale, tag, date / time, and the like to be searched to the Web server 7. Then, after specifying the terminal ID, the Web server 7 transmits a content search to the position data storage server 9 based on the search request. The Web server 7 generates area information for the user from the search result and the user profile, and transmits the area information to the communication terminal 11 as area information. Here, as the regional information for the user, for example, when it is determined that the image is created by a user registered in his / her friend or community, it is more dynamically added to the point of the already registered image data. Points are assigned, and the image data is displayed in descending order of the updated number of points.

  FIG. 5 is a diagram showing an example of the image data management table in the position data storage server 9. Here, for the sake of convenience, it is assumed that the user ID of the creator + creation date / time + image file extension is used for the file name of the image data. Of course, the file name may be in other formats. As shown in this table, the image file includes the creator's user ID and terminal ID, as well as the position information of the object (here, latitude and longitude), the number of accesses to the image file, the number of bookmarks, and the evaluation of the creating user Points are recorded. Assume that the creation user's evaluation points are given by a separate evaluation system. Further, when registering an image file in this table, it is desirable to obtain an actual address from latitude and longitude information and add it to this table.

  When the user searches for the image data related to the area information, the profile data of the user who requested the search is obtained by referring to the community management server 8. In the user profile data, information on friends, colleagues, and communities is recorded together with the user ID and terminal ID by an SNS (Social Network System). By searching this content information in consideration of the profile information, it is possible to search for image data based on user preferences. An actual search example will be described with reference to the following figure.

  FIG. 6 is a diagram illustrating an example of a search screen for searching for image data associated with position information on a map. For example, the user inputs an address (may be a zip code) of an area to be searched for in the address input area 21 and presses the search button 22. At this time, the area map of the target area is displayed in a matrix as indicated by reference numeral 23 in the figure. Here, the scale of the displayed map can be changed with a scale operation bar indicated by reference numeral 27. If there is an image to be displayed in this area, the image of the target object (the one with the highest priority) is displayed on the target matrix, as indicated by reference numerals 24, 25, and 26. The display of the image data here may be a thumbnail or an icon. Furthermore, not only image data but also comments and advertisements related to the target image may be displayed as indicated by reference numeral 24a. When there are a plurality of images in one matrix, the image with the higher priority (point) is displayed with priority. Further, since the size of the matrix is changed by changing the scale of the map to be displayed, the displayed image also changes. For example, when the scale is doubled, the matrix indicated by reference numeral 24 is further divided into four, and thumbnails and icons of different images can be displayed.

  In the area indicated by reference numeral 28, tags that can be used for narrowing search are shown. For example, when a “ramen” tag is clicked, an image having a tag related to “ramen” is preferentially displayed. Further, by operating the operation bar for the search target period 29, the date and time range to be searched can be specified. In other words, it is possible to narrow down according to whether or not the date when the image is registered is in the search target period.

  Further, information based on the group community is displayed in the area indicated by reference numeral 31. Individually, the latest date and time of image data registered by a user who is closely related to the user is displayed. By combining such community information and the various functions described above, a more accurate search can be performed.

  FIG. 7 shows another example of the search screen. Here, the search result is displayed by specifying “Tokyo” as the address (position information), “fireworks” as the tag, and “7/15 to 8/15” as the time series (date information). . In the case of this search condition, as shown in the figure, three “fireworks display” icons (indicated by ◎ in the figure) that match the conditions are displayed at corresponding positions on the map. Separately from this example, if you specify the time period in July as the time series, only “Sumidagawa fireworks display” will be displayed. If you specify the time period in August as the time series, “Jingu Gaien fireworks display” and “Tokyo Bay” will be displayed. "Great Fireworks Festival" will be displayed. Further, when each icon is clicked, more details such as comments and advertisements are displayed as in the case of FIG. Of course, an image of fireworks as shown in the figure may be displayed. Here, when there are a plurality of images of “Tokyo Bay Fireworks Festival”, an image with high weighting, for example, an image highly evaluated by many users may be displayed sequentially (automatically or manually). . As described above, by combining the position information, the tag, and the date and time information with the weighting data (evaluation points), the image desired by the user can be searched with high accuracy and can be displayed visually.
