  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all combinations of the features described in the embodiments are necessarily indispensable to the solution of the invention.

  FIG. 1 is a diagram illustrating the entire information processing system. The information processing system according to the present embodiment includes an information processing apparatus 100, a terminal 202 of an information viewer 200, terminals 303 and 304 owned by an information provider 300, a terminal 305 owned by an information provider 301, and an information provider 302. It has a terminal 306 that it owns. The terminal 303, the terminal 304, the terminal 305, and the terminal 306 may be collectively referred to as an information provider terminal.

  The information provider 300 owns the terminal 303 and the terminal 304. The information provider 301 owns the terminal 305. The information provider 302 owns the terminal 306. Each of the terminal 303, the terminal 304, the terminal 305, and the terminal 306 may be any one of a lens-integrated digital camera, a lens-interchangeable digital camera, a mobile phone with a digital camera, a digital video camera, and the like.

  The terminal 303, the terminal 304, the terminal 305, and the terminal 306 each photograph the incident site 400, and image information including the image 402 of the incident site 400 is transmitted to the information processing apparatus 100. The information processing device 100 receives and stores the image information. Further, the information processing apparatus 100 notifies the terminal 202 of the information viewer 200 by e-mail or the like based on the number of pieces of image information that match the search condition set by the information viewer 200.

  The information processing device 100 is a data server or the like. The terminal 202 of the information viewer 200 is a personal computer, a smartphone, or the like.

  FIG. 2 shows a functional block diagram of the terminal 304. The terminal 303 includes an imaging unit 308, a timing unit 310, a memory 312, a position identification unit 314, a communication unit 316, a recording control unit 318, and a recording medium 320. Note that the terminals 304, 305, and 306 also have the same functions, and thus description thereof will be omitted.

  The timer 310 outputs date and time information indicating the current date and time. For example, the clock unit 310 provides the recording control unit 318 with date and time information at the time of imaging by the imaging unit 308. The memory 312 stores device ID information indicating a device ID for specifying the terminal 303 and user ID information indicating a user ID for specifying the information provider 300 using the terminal 304.

  The position specifying unit 314 receives signals from a plurality of GPS satellites or signals from a base station from a communication network of the portable terminal, and calculates position information indicating the position of the terminal 303. Alternatively or additionally, the position specifying unit 314 may directly obtain the position information indicating the position of the terminal 303 from outside. The position specifying unit 314 further acquires orientation information indicating the orientation of the terminal 303 by detecting the orientation of the terminal 303 with respect to the direction of gravity and the orientation with respect to the earth's magnetism.

  The imaging unit 308 captures an image of a subject according to an operation of the information provider 300 and generates image data of the subject. The recording control unit 318 records the image data generated by the imaging unit 308 on the recording medium 320. The recording control unit 318 acquires date and time information when the image capturing unit 308 performed the image capturing operation from the clock unit 310 and adds it to the image data as image capturing date and time information. The recording control unit 318 further acquires the position information and the azimuth information when the imaging unit 308 performs the imaging operation from the position identification unit 314, and adds the acquired information to the image data as the imaging position information. The recording control unit 318 further acquires the device ID and the user ID information from the memory 312, and adds the device ID and the user ID to the image data. The recording control unit 318 records, on the recording medium 320, image data including shooting date and time information, position information, azimuth information, device ID information, and user ID information as additional information. The recording control unit 318 records an image file including image data and additional information on the recording medium 320. An example of the format of the information to be added is Exif. For example, the recording control unit 318 records an image file in the Exif format on the recording medium 320. The image data and the additional information read from the recording medium 320 are provided to the communication unit 316 as image information.

  The communication unit 316 communicates with the information processing device 100. For example, the communication unit 316 transmits the image data generated by the imaging unit 308 to the information processing device 100. The communication unit 316 transmits the image data recorded on the recording medium 320 to the information processing device 100.

  When the communication unit 316 transmits the image data to the information processing device 100, the communication unit 316 transmits at least the photographing position information to the information processing device 100. For example, the communication unit 316 transmits, to the information processing apparatus 100, data of an Exif-format image file including shooting position information, which is read from the recording medium 320. Which additional information should be transmitted besides the photographing position information is set in advance by the information provider 300, and information indicating the additional information to be transmitted is stored in the memory 312, for example. The communication unit 316 transmits, to the information processing apparatus 100, data of an image file including the additional information set to be transmitted and the photographing position information.

  Note that the communication unit 316 may transmit image data to the information processing apparatus 100 every time an imaging operation is performed by the imaging unit 308. For example, when an image file is recorded on the recording medium 320 according to an imaging operation of the imaging unit 308, the communication unit 316 transmits the image file read from the recording medium 320 to the information processing device 100. It is sufficient that the communication unit 316 transmits the additional information to be transmitted including the photographing position information to the information processing apparatus 100 in association with the image data, and transmits the additional information and the image data by any method other than the image file. You may.

  FIG. 3 is a block diagram of the information processing apparatus 100. The information processing apparatus 100 includes an information acquisition unit 102, a clock unit 104, an information storage unit 106, a setting reception unit 108, a measurement unit 110, a notification unit 112, and an image generation unit 114. The information storage unit 106 includes an image information storage unit 120 that stores image data, a search information storage unit 122 that stores search information including search conditions, and a point information storage unit 124 that stores point information.

  The timer 104 outputs date and time information indicating the current date and time. For example, the timing unit 104 provides the information acquisition unit 102 with date and time information when the information acquisition unit 102 received the image information.

  The information acquisition unit 102 receives image information from each of the terminal 303, the terminal 304, the terminal 305, and the terminal 306, and stores the image information in the image information storage unit 120. The information acquisition unit 102 further acquires date and time information when the image information was received from the clock unit 104, and stores the acquired date and time information as reception date and time information in the image information storage unit 120 in association with the image information.

  The setting receiving unit 108 acquires the search condition from the terminal 202 and stores the search condition in the search information storage unit 122 in association with the information viewer 200. The measuring unit 110 reads out a search condition corresponding to the information viewer 200 from the search information storage unit 122, and counts the number of pieces of image information satisfying the search condition. For example, the measuring unit 110 may include the number of times image information that satisfies the search condition is received, the number of information provider terminals that transmit image information that satisfies the search condition, and the information provider terminal that transmits image information that satisfies the search condition. And the number of information providers who own the. The number of times image information that satisfies the search condition is counted as one reception of one piece of image information that satisfies the search condition. When the number of pieces of image information measured by the measuring unit 110 exceeds a threshold set in association with the information viewer 200, the notifying unit 112 notifies the terminal 202 of the fact. Note that the number of pieces of image information measured by the measurement unit 110 may be referred to as the number of times of shooting.

  The image generation unit 114 creates a display image in which the shooting position is superimposed on the map image and causes the terminal 202 to display the display image. When the image information or the like is viewed on the terminal 202, the image generation unit 114 acquires the device ID or the like from the terminal 202, assigns a preset point to the device ID, and stores the point in the point information storage unit 124. Note that a preset point may be given to the user ID of the information provider who owns the information provider terminal identified by the device ID and stored in the point information storage unit 124.

  Each function of the information processing apparatus 100 may be provided as a computer program and executed by being installed in the information processing apparatus 100. In this case, the program may be provided and installed on a medium such as the CD-ROM 130 or via a network such as the Internet. The image data generated by the information provider terminal such as the terminal 304 may be stored in the information provider terminal such as the terminal 304 and the information processing apparatus 100 as described above. On the other hand, the image data generated by the information provider terminal may be stored in the information processing apparatus 100 without being recorded in the information provider terminal such as the terminal 304.

  FIG. 4 is a functional block diagram of the terminal 202 of the information viewer 200. The terminal 202 includes a setting input unit 204, a notification receiving unit 206, and a display unit 208.

  The setting input unit 204 receives an input of a search condition from the information viewer 200 and transmits the search condition to the setting receiving unit 108 of the information processing apparatus 100. The notification receiving unit 206 receives a notification from the notification unit 112 of the information processing device 100.

  The display unit 208 displays the display image generated by the image generation unit 114 of the information processing device 100. When the information of the notification received by the notification receiving unit 206 is visual information such as a mail, the display unit 208 displays the information of the notification. Thereby, the information viewer 200 browses the display unit 208 and visually recognizes the position information corresponding to the position that exceeds the search condition set by the information viewer 200.

  An example of the information viewer 200 is an official of a news organization. The information viewer 200 can know that an event having a high news characteristic has occurred by the notification from the information processing apparatus 100, and can widely report the event. On the other hand, each of the information provider 300, the information provider 301, and the information provider 302 is not limited to a person related to the news media, and may be a participant widely recruited from the general public. Although the number of persons involved in the news media is limited, the news can be efficiently utilized by utilizing image information from many general information providers such as the information provider 300, the information provider 301, and the information provider 302. You can know that a highly likely event has occurred.

  FIG. 5A shows an example of data stored in the image information storage unit 120. The image information storage unit 120 stores a shooting date and time, a reception date and time, a still image and a moving image, a moving image length, shooting position information, a thumbnail, and main image data in association with the device ID and the user ID. When image information is received by the information acquisition unit 102 from the terminal 304 or the like, a new line of image information associated with the device ID of the terminal 304 is added to the image information storage unit 120.

  In the device ID column, for example, the serial number of the terminal 304 owned by the information provider 300 is stored. In the user ID column, for example, a symbol assigned from the information processing apparatus 100 by user registration of the terminal 304 is stored as a user ID.

  The shooting date and time column stores shooting date and time information included in the image information received by the information acquisition unit 102. The reception date and time column stores reception date and time information at which the information acquisition unit 102 has received the image information. Note that, when the image information received by the information acquisition unit 102 does not include the shooting date and time information, an invalid value “−” is stored in the shooting date and time column.

  In a separate column of a still image and a moving image, “still image” is stored when the transmitted image information is a still image, and “moving image” is stored when the transmitted image information is a moving image. The moving image length field stores the length of the moving image in seconds (s). In the case of a still image, an invalid value “−” is stored in the moving image length column.

  The shooting position (latitude) column stores “N” for north latitude and “S” for south latitude based on shooting position information included in image information. Following these, the latitude is stored as a numerical value (unit: d (degree), m (minute), s (second)). Similarly, the shooting position (longitude) field stores the longitude of the east longitude “E” and the west longitude “W” and the numerical value of the longitude (unit d (degree), m (minute), s (second)).

  The column of the shooting position (altitude) stores an altitude (unit: m) based on the height of the average sea level based on the shooting position information included in the image information. The shooting position (azimuth) stores an angle (unit: degree) with respect to a specific direction. In the present embodiment, a clockwise angle based on the north direction is stored.

  For example, the shooting date and time and shooting position of the first frame of the moving image are stored in the image information storage unit 120 as the shooting date and time and shooting position in the case of a moving image. Instead, the shooting date and time and shooting position of any one of the frames may be stored in the image information storage unit 120 as separate image information for each of the plurality of frames. In the case of a moving image, the shooting time and the shooting position stored in the image information storage unit 120 may have a certain width, and the time zone and the moving range during the shooting of the moving image may be used as the shooting time and the shooting position.

  In the thumbnail and main image fields, the image data itself is stored when there is information, and “None” is stored when there is no information.

  FIG. 5B is a flowchart illustrating an operation in which the information processing apparatus 100 acquires image information. The operation flow in FIG. 5B is started when the information provider terminal notifies that the image information is to be transmitted. 5B is executed at an arbitrary timing while the power of the information processing apparatus 100 is ON.

  In step S201, the information acquisition unit 102 of the information processing device 100 acquires image information from the communication unit 316 of the terminal 304. In step S202, the information acquisition unit 102 stores the acquired image information in the image information storage unit 120.

  In step S203, the information acquisition unit 102 acquires the reception date and time from the clock unit 104, and stores the reception date and time information of the image information in the image information storage unit 120. As a result, the information shown in FIG. 5A is stored in the image information storage unit 120. When the reception date and time information is stored in the image information storage unit 120, the operation flow illustrated in FIG. 5B ends.

  FIG. 6A shows an example of data stored in the search information storage unit 122. The search information storage unit 122 stores a synchronization interval and a search condition in association with the viewer ID. The search conditions include a measurement method, a start time, an end time, a region, a region size, and a threshold.

  The ID of the information viewer 200 is stored in the column of the viewer ID. An example of the viewer ID is an account for logging in to the terminal 202. The synchronization interval column stores an interval (unit: S) at which the search for the image information is automatically updated.

  When a plurality of pieces of image information are received from the same information provider terminal and they are collectively counted as one, the “unit of terminal” is stored in the column of the counting method. When a plurality of pieces of image information are received from the same information provider and are measured as one, “user unit” is stored. Regardless of the information provider terminal that transmitted the image information and the information provider that owns the information provider terminal, the “image unit” is stored when a plurality of pieces of image information are received and measured separately.

  By selecting “per terminal” as the measurement method, the information provider 300 or the like is notified to the information viewer 200 when the information provider 300 or the like captures a large amount of images at the same time on the same terminal 303 or the like despite low newsability. Is prevented. By selecting the “user unit” as the measurement method, the information viewer 200 is notified when the same information provider takes a large amount of images at a time on a different terminal 303 or the like despite low newsability. Is prevented. By selecting “image unit”, the incentive of image information by the information provider 300 or the like can be increased. Alternatively or additionally, in the column of the measurement method, when a plurality of pieces of image information are received from the same information provider 300 or the like, whether they are collectively measured as one or measured separately. May be stored.

  The start time and the end time, which are one of the search conditions, are stored in the column of the start time and the end time in the date and time expressed in the Christian era. The search target period is a period from the date and time represented by the start time to the date and time represented by the end time. Note that an invalid value “−” may be stored in the start time column, and only the time may be stored in the end time column. When only the time is stored in the end time column, the hour and minute indicating the length of the search target period are stored in the end time column. The length of the search target period indicates the length of time from the current time. In this case, the search target period is a period from the time preceding the current time by the time length to the current time.

  The area column stores information for identifying an administrative division, which is one of the search conditions. The area column may store the name of the administrative division that is one of the search conditions. In the area column, latitude and longitude indicating the area to be searched may be stored. For example, when the area to be searched is set in a rectangular range having four points as vertices, the latitude and longitude of each of the two points corresponding to the two vertices forming the diagonal of the rectangle are stored in the area column. May be.

  Further, the area size (unit: m square) serving as a unit for counting image information is stored in the area size column. That is, the area size column stores information indicating the size of the unit area for which the image information is to be counted. The threshold column stores the number of thresholds used to determine when to notify the information viewer 200 when the number of times of imaging measured by the measurement unit 110 under the search conditions.

  FIG. 6B shows an example of alarm information stored in the search information storage unit 122. The search information storage unit 122 stores the search target period, the size of the area, the threshold value, and the address in association with the viewer ID.

  Information similar to the corresponding items described with reference to FIG. 6A is stored in the viewer ID, the area size, and the threshold. Therefore, the description of the viewer ID, the area size, and the threshold is omitted. The search target period column stores the hour and minute indicating the length of the search target period. The length of the search target period indicates the length of time from the current time. The search target period is a period from the time preceding the current time by the time length to the current time. The address column stores address information of a notification destination to be notified when the number of image information measured by the measurement unit 110 exceeds the threshold set in the alarm information.

  FIG. 7 shows an example of the information browsing screen 210 displayed on the display unit 208. The information browsing screen 210 is displayed on the display unit 208 when the terminal 202 executes an information browsing program.

  One of two types of time conditions can be set. The first corresponds to the radio button 216, and a time period set back from the current time by a set time is set as a search condition. The second corresponds to the radio button 217, in which a start time and an end time are set, and the interval between them is set as a search condition. The set radio button 216, 217 is displayed as a double circle.

  In the input field corresponding to the radio button 216, the information viewer 200 can input numerical values of the hour and minute of the time to be searched from the present time. Further, the information viewer 200 can change the numerical value displayed in the input field. In the input field corresponding to the radio button 217, the information viewer 200 can input a numerical value indicating the date and time of the start time and the date and time of the end time indicating the period to be searched. Further, the information viewer 200 can change the numerical value displayed in the input field.

  Below the time setting menu, a target area setting button 226 selected when setting a target area and an alarm setting button 227 selected when setting an alarm are displayed. These buttons will be described later.

  In the menu section 212, an area display 218 for displaying a count target area and a threshold display 219 for displaying a threshold of the number of times of photographing are displayed on the right side of the time setting menu. In the input field corresponding to the area display 218, the size of the unit area to be counted is displayed as a numerical value. The information viewer 200 can input a numerical value into the input field, and the information viewer 200 can change the numerical value displayed in the input field. In an input field corresponding to the threshold value display 219, a threshold value of the number of pieces of image information that satisfies the search condition is numerically displayed. The information viewer 200 can input a numerical value into the input field, and the information viewer 200 can change the numerical value displayed in the input field.

  Below the area display 218 and the threshold value display 219 in the menu section 212, a check box 220 used to display a corresponding area, a previous button 221 and a next button 222 used to select a square pin displaying the count result. Is displayed. These buttons will be described later.

  A display update button 223 selected when updating the display of the search result, a synchronization setting button 224 selected when setting the synchronization setting and the shooting count condition are displayed in the right area in the menu section 212, And an end button 225 to be selected is displayed in order in a line in the vertical direction.

  FIG. 8 shows a setting screen 230 for setting synchronization settings and shooting count conditions. The setting screen 230 is displayed on the display unit 208 of the terminal 202 when the synchronization setting button 224 in FIG. 7 is selected with the mouse cursor and clicked. The setting screen 230 has a synchronization setting unit 231, a shooting count setting unit 235, and a close button 239.

  The synchronization setting section 231 includes an input field 232 for inputting a synchronization interval with the information processing apparatus 100. The information viewer 200 can input the synchronization interval with the information processing apparatus 100 in the input field 232 by using a numerical value. The time (unit: S) input by the information viewer 200 is displayed in the input column 232. If the synchronization interval has already been set, the setting screen 230 is displayed in a state where a numerical value indicating the synchronization interval has been input in the input field 232.

  Radio button 236, 237 and 238 which can be selected alternatively are displayed on the number-of-times-of-imaging count setting section 235. The radio button 236 corresponds to “terminal unit” in which, when a plurality of pieces of image information are received from the same terminal ID, they are collectively measured as one. The radio button 237 corresponds to a “user unit” in which, when a plurality of pieces of image information are received from the same information viewer, they are collectively measured as one. The radio button 238 corresponds to an “image unit” that separately measures a plurality of pieces of image information from the same terminal ID. When the information viewer 200 selects any radio button, a double circle is displayed on the selected radio button.

  A close button 239 is displayed on the lower right side of the setting screen 230. Until the information viewer 200 presses the close button 239, the selection of the synchronization setting and the number of times of photographing can be changed. Then, when the close button 239 is selected by the information viewer 200, the selection of the synchronization interval and the number of times of shooting displayed in the input field 232 at that time is accepted by the setting input unit 204 as a search condition. The setting input unit 204 transmits the search condition to the setting receiving unit 108 of the information processing device 100. The setting receiving unit 108 stores the received search conditions in the search information storage unit 122. For example, the information on the synchronization interval and the information on the measurement method described with reference to FIG. 6A are stored or updated.

  FIG. 9 is a flowchart illustrating an operation for setting search information for an alarm. FIG. 10 is a diagram showing a setting screen 240 for setting search information for an alarm. The operation flow in FIG. 9 starts when the alarm setting button 227 in FIG. 7 is selected and the setting reception unit 108 of the information processing apparatus 100 receives the selection.

  In step S <b> 100, the setting receiving unit 108 checks the search information storage unit 122 and determines whether the search information of the viewer ID that matches the login ID is stored in the search information storage unit 122. If the setting reception unit 108 determines that the search information of the viewer ID that matches the login ID is stored, the process proceeds to step S101. On the other hand, if the setting receiving unit 108 does not store the search information of the viewer ID that matches the login ID, the process proceeds to step S102.

  In step S101, the setting input unit 204 displays, for example, a setting screen 240 shown in FIG. The setting screen 240 has a setting column 241 for a period to be measured, a setting column 245 for a measurement target area, a setting column 248 for a threshold value of image information, and a setting column 250 for an alarm transmission destination mail address. The setting field 241 includes input fields 242 and 243. The setting column 245 includes an input column 246. The setting column 248 includes an input column 247. The setting field 250 includes an input field 251, an add button 252, and a registration field 253.

  The setting receiving unit 108 reads out the search information of the above-mentioned viewer ID stored in the search information storage unit 122 and transmits the search information to the setting input unit 204. The setting input unit 204 displays a setting screen 240 on which numerical values based on the search information are displayed on the display unit 208.

  In step S101, the setting input unit 204 displays search conditions in the input fields 242 and 243, the input field 246, and the input field 247 based on the search information, displays a mail address in the registration field 253, and The input from the information viewer 200 to the columns 242, 243, 246, 247 and 251 and the registration column 253 is received.

  Note that the numerical values displayed in the input fields 242 and 243 correspond to hours and minutes of the time to be searched from the present time. The numerical value displayed in the input column 246 corresponds to the size of the geographical range to be searched. The numerical value displayed in the input field 247 corresponds to the threshold value of the number of pieces of image information satisfying the search condition. The mail address displayed in the registration field 253 corresponds to the mail address of the alarm transmission destination. The setting input unit 204 proceeds to step S103, and waits for an input in any of the input fields 242, 243, 246, 247, and 251 and the registration field 253.

  In step S102, the setting input unit 204 displays the setting screen in which the input fields 242, 243, 246, 247, and 251 and the registration field 253 are blank on the setting screen 240, and receives an input from the information viewer 200. When the setting input unit 204 receives an input in any of the input fields 242, 243, 246, 247, and 251, the process proceeds to step S103.

  In step S103, the setting input unit 204 determines whether a value has been input in any of the input fields of the search target period, the count target area, and the threshold. Specifically, the setting input unit 204 determines whether a value has been input in at least one of the input fields 242, 243, 246, and 247. When the setting input unit 204 determines that a value has been input in any of the input fields of the measurement target period, the target area, and the threshold, the process proceeds to step S104. When the setting input unit 204 determines that a value has not been input in any of the input fields of the measurement target period, the target area, and the threshold, the process proceeds to step S107.

  In step S104, the setting input unit 204 determines whether values have been input from the information viewer 200 to all of the input fields 242, 243, 246, and 247. If it is determined that values have been input to all of the input fields 242, 243, 246, and 247, the process proceeds to step S109. On the other hand, if it is determined that any of the input fields 242, 243, 246 and 247 has not been input, the process proceeds to step S105.

  In step S105, the setting input unit 204 checks the number of input fields for which no numerical value has been input. If the setting input unit 204 determines that only one of the input fields 242, 243, 246, and 247 has not been input, the process proceeds to step S106. On the other hand, if the setting input unit 204 determines that two or more of the input columns among the input columns 242, 243, 246, and 247 have not been input, the process returns to S103, and the setting input unit 204 returns to the input columns 242, 243, Wait for input to any of 246, 247 and 251 and the registration field 253.

  In step S106, the setting input unit 204 receives, from the setting receiving unit 108, the recommended value of the input field where no value has been input, displays the value in the input field, and proceeds to step S109. Here, the setting reception unit 108 presents a recommended value of at least one of the length of the search target period, the size of the area, and the threshold.

  In this case, the setting receiving unit 108 may present the mode set by another information viewer. If the attribute of the information viewer is registered, for example, whether the information is a news organization or not, if it is a news organization, the setting reception unit 108 calculates the mode value. Information viewers having the same attribute may be extracted as “other information viewers”. Alternatively or additionally, the setting receiving unit 108 may present the recommendation value so that one or more areas where the search condition exceeds the threshold in the current image information can be created. As described above, by presenting the recommended value, a value serving as a clue for setting can be shown to the unfamiliar information viewer 200.

  In step S107, the setting input unit 204 determines whether the mail address has been added or deleted. Specifically, the setting input unit 204 determines whether or not any of the operation of inputting the input column 251 and pressing the add button 252 and the operation of deleting the mail address from the registration column 253 have been performed. If the setting input unit 204 determines that the mail address has been added or deleted, the process proceeds to step S108. If it is determined that neither the email address nor the email address has been added, the process proceeds to step S111.

  If it is determined in step S107 that the input to the input field 251 and the operation of pressing the add button 252 have been performed, the setting input unit 204 adds the mail address displayed in the input field 251 to the registration field 253 in step S108. Is displayed and the process proceeds to step S109. If the mail address has already been displayed in the registration field 253, the setting input unit 204 adds the mail address displayed in the input field 251 to the registration field 253 in addition to the mail address displayed in the registration field 253. It is displayed alongside the displayed email address. If it is determined in step S107 that the operation of deleting the mail address from the registration field 253 has been performed, in step S108, the setting input unit 204 deletes the mail address to be deleted from the registration field 253, and proceeds to step S109. move on. It should be noted that the deletion of the e-mail address from the registration field 253 is performed by selecting the item of the deletion from the context menu displayed by pressing the right mouse button with the corresponding line of the e-mail address to be deleted selected. May be made.

  In step S109, the setting input unit 204 determines whether values are displayed in all of the input fields 242, 243, 246, and 247 in the setting screen 240, and whether one or more mail addresses are displayed in the registration field 253. . Then, when it is determined that all are displayed, the process proceeds to step S110. On the other hand, when it is determined that not all are displayed, the process returns to S103, and the setting input unit 204 waits for input to any of the input fields 242, 243, 246, 247 and 251, the registration field 253, and the close button 254.

  In step S110, the setting input unit 204 activates the lower right close button 254 in the setting screen 240. By enabling the button 254, the button 254 can be selected by the information viewer 200. After step S110, the process returns to step S103, and the setting input unit 204 waits for input into any of the input fields 242, 243, 246, 247, and 251 and the registration field 253.

  In step S111, the setting input unit 204 determines whether the close button 254 has been selected. If the setting input unit 204 determines that the close button 254 has been selected, the process proceeds to step S112. When the setting input unit 204 determines that the button 254 has not been selected, the process returns to step S103, and the input to any of the input fields 242, 243, 246, 247, and 251, the registration field 253, and the close button 254 is performed. Wait for. Thus, the information viewer 200 can change the search information displayed on the setting screen 240 until the user presses the button 254.

  In step S112, the setting input unit 204 transmits the search information displayed on the setting screen 240 to the setting receiving unit 108. The setting receiving unit 108 stores the received search information in the search information storage unit 122. The received search information is stored in the search information storage unit 122 as alarm information described with reference to FIG. 6B. Thus, the operation flow illustrated in FIG. 9 ends.

  FIG. 11 is a diagram showing a setting screen 260 for setting a target area as a search condition by administrative division. The setting screen 260 is displayed on the display unit 208 when the target area setting button 226 on the information browsing screen 210 in FIG. 7 is selected.

  The setting screen 260 has a condition selection unit 261 and a map unit 262. The radio button 263 for setting the map display worldwide, the radio button 264 for setting the administrative division, and the radio button 265 for setting the map are arranged in a vertical line in the upper left area in the condition selection unit 261. Is displayed.

  When the radio button 263 to be set in the whole world is selected in the condition selection unit 261, a world map is displayed in the map display area 271, and an arbitrary country can be selected. On the other hand, when the radio button 264 set in the administrative division is selected, the four pull-down menus displayed in the right area in the condition selection section 261 become valid. When an item is selected from one of the four pull-down menus, the selection item in the pull-down menu on the right of the pull-down menu dynamically changes according to the selected item.

  In the example of FIG. 11, the Asian region in the whole world is selected by the pull-down menu 266 on the left end, Japan in the Asian region is selected on the right by a pull-down menu 267 on the right, and the pull-down on the right is further selected. In the menu 268, the Kanto region is selected. With the selection of the Kanto region, the Kanto region is displayed in the map display area 271, and the regions other than the Kanto region are grayed out. From this state, by selecting a prefecture in the Kanto region from the pull-down menu 269 on the right side, the selected prefecture can be displayed.

  When it is detected that the close button 270 is pressed on the setting screen 260, the setting input unit 204 transmits each item selected at that time to the setting receiving unit 108 of the information processing apparatus 100 as a search condition. . The setting receiving unit 108 stores the received search conditions in the image information storage unit 120.

  FIG. 12 is a diagram showing a setting screen for setting a target area on a map. 12, the same elements as those in FIG. 11 are denoted by the same reference numerals, and redundant description will be omitted.

  When the radio button 265 of “Set by map” is selected from the setting screen 260 in FIG. 11, the setting input unit 204 displays a selection frame 273 on the map display area 271. The size of the selection frame 273 is variable according to an input from the terminal 202, and the position can be moved.

  Further, a cursor control 214 for changing the map display position and a slider bar 215 for changing the map display magnification are displayed at the left end of the map display area 271, and the target area can be arbitrarily selected by operating these. When it is detected that the close button 270 is pressed on the setting screen 272, the setting input unit 204 uses each item selected at that time and the area indicated by the selection frame 273 as a search condition as the search condition. Is transmitted to the setting receiving unit 108. For example, when the selection frame 273 is rectangular, the setting input unit 204 transmits the latitude and longitude of each of the two points indicated by the two vertices forming the diagonal of the rectangle to the setting receiving unit 108 of the information processing apparatus 100. You may.

  FIG. 13 is a flowchart illustrating an operation of measuring image information. FIG. 14 shows an example of a display screen displaying the measurement result of the image information. FIG. 15 shows an example of a display screen for displaying position information of image information. FIG. 16 shows an example of a display screen for displaying an image of image information. The operation flow in FIG. 13 is started in response to the execution of the above-described information browsing program in terminal 202. The operation described with reference to the flowchart in FIG. 13 is performed in parallel with the operation described with reference to the other flowcharts in FIGS. 5B and 9.

  In step S300, the measuring unit 110, the setting receiving unit 108, and the image generating unit 114 acquire the search information stored in the search information storage unit 122 in association with the viewer ID of the information viewer 200.

  Subsequently, in step S302, the information processing apparatus 100 causes the display unit 208 to display an information browsing screen. For example, the information processing apparatus 100 causes the display unit 208 to display the information browsing screen 210 shown in FIG. Specifically, the setting receiving unit 108 transmits the search information obtained from the search information storage unit 122 to the setting input unit 204, and causes the menu unit 212 of the information browsing screen 210 to display the search conditions included in the search information. . Further, the image generation unit 114 generates a map image including the search target area indicated by the search condition included in the search information, and causes the map unit 211 of the information browsing screen 210 to display the map image 276.

  In step S304, the measuring unit 110 counts the number of pieces of image information that satisfy the search condition included in the search information acquired from the search information storage unit 122, out of the image information stored in the image information storage unit 120.

  Specifically, the measuring unit 110 determines that the shooting date and time indicated by the shooting date and time information included in the image information is included in the search target period set as the search condition, and the shooting position indicated by the shooting position information is the search condition. The number of pieces of image information included in the area set as is measured. In this case, when the value of the start time is invalid “−” among the search conditions stored in the search information storage unit 122, the measurement unit 110 sets the value of the end time to “time going back from the present time”. Judge to determine the search period.

  Regarding a specific example of the measurement by the measuring unit 110, the temporal range of the search condition is currently “1 hour before 13:00 on May 23, 2012”, the regional range is “Kanto”, A case where the unit of a simple mesh is “500 m square” will be described.

  The measuring unit 110 refers to the column of the shooting date and time of the image information storage unit 120, and the image date and time information corresponding to “May 23, 2012 12:00:00 to May 23, 2012 13:00” Is extracted. Here, when an invalid value “−” is stored in the field of the shooting date and time in the image information storage unit 120, the measuring unit 110 determines that the reception date and time are included in the temporal range of the search condition. Information is also extracted.

  The measuring unit 110 further divides the regional range “Kanto” of the search condition by a unit “500 m square” of the mesh, and calculates the latitude and longitude corresponding to each of the divided mesh regions. The measuring unit 110 refers to the imaging position of the image information extracted by the temporal search condition in the image information storage unit 120, and is included in any one of the mesh regions or included in any one of the mesh regions. Determine if there is.

  The measuring unit 110 totals the number of pieces of image information whose shooting position is included in the mesh area for each mesh area. In this case, when the counting method associated with the viewer ID in the search information storage unit 122 is “image unit”, the measuring unit 110 uses the total number as a measurement value as it is. When the counting method is “per terminal”, the measuring unit 110 refers to the image information storage unit 120, and the photographing position is included in the same mesh area and is associated with the same device ID. A total value obtained by collecting one or more pieces of image information into one is referred to as a measured value. When the counting method is “user unit”, the measuring unit 110 refers to the image information storage unit 120, and the shooting position is included in the same mesh area and is associated with the same user ID. A total value obtained by collecting one or more pieces of image information into one is referred to as a measured value.

  The measurement unit 110 compares the threshold value stored in the search information storage unit 122 in association with the viewer ID with the measured value for each mesh area. If there is a mesh area whose measured value exceeds the threshold, the image generation unit 114 generates a map image 276 in which square pins 277 are superimposed at positions corresponding to the mesh area, and displays the map image 276 on the display unit 208. Let it. For example, the display unit 208 displays a display screen 275 shown in FIG.

  In the example of the display screen 275 of FIG. 14, five square pins 277 are displayed. A broken line frame 278 indicates that the information viewer 200 selects the square pin 277 surrounded by the broken line frame 278 among the plurality of square pins 277.

  In the present embodiment, square pins 277 are shown in mesh areas where the number of image information exceeds the threshold. Alternatively or alternatively, a plurality of pin shapes or colors may be used. For example, a pin corresponding to an area that greatly exceeds the threshold value may be displayed in a larger or darker color than other pins.

  In step S306, the information processing apparatus 100 determines whether any one of the square pins 277 has been selected by the information viewer 200 among the plurality of square pins 277. If it is determined that any of the square pins 277 has been selected, the process proceeds to step S308. If it is determined that none of the square pins 277 has been selected, or if no square pin 277 is displayed, the process proceeds to step S314.

  In FIG. 14, the broken line frame 278 is moved when the information viewer 200 selects the previous button 221 or the next button 222. Therefore, the information viewer 200 can select an arbitrary square pin 277. Alternatively, the square pin 277 may be selected with a mouse cursor and clicked to select it. When the next button 222 is clicked, the broken line frame 278 is moved, for example, in the descending order of latitude. When the square pin 277 exists in an area that is not currently displayed on the map, the position of the map display may be changed to display the square pin in the state of the broken line frame 278.

  In step S308, the information processing apparatus 100 determines whether the information viewer 200 has checked the check box 220 for displaying the corresponding position. If it is determined that the check box 220 has been checked by the information viewer 200, the process proceeds to step S309. If it is determined that the check box 220 is not checked, the process proceeds to step S314.

  In step S309, the image generation unit 114 generates a map image 281 of the mesh area corresponding to the square pin 277 selected by the information viewer 200. At this time, the image generation unit 114 generates a map image 281 in which the round pin 282 is superimposed on the position of the image information where the shooting position exists, transmits the map image 281 to the display unit 208, and displays the map image 281. The process proceeds to step S310.

  In step S310, the image generating unit 114 determines whether the display of the thumbnail image corresponding to the selected round pin 282 has been requested by the information viewer 200 selecting the round pin 282. If it is determined that the display of the thumbnail image has been requested, the thumbnail image is displayed, and the process proceeds to step S311. If the display of the thumbnail image is not requested for a predetermined period, the process proceeds to step S314. In FIG. 15, a dark colored round pin 283 indicates a state selected by the information viewer 200.

  The information viewer 200 can change the selected round pin 283 by selecting the previous button 221 and the next button 222. Therefore, the information viewer 200 can select an arbitrary round pin 282. Alternatively, the round pin 282 may be selected with a mouse cursor and selected by clicking.

  When any one of the round pins 282 is selected, the image generation unit 114 reads out the image information of the shooting position corresponding to the position of the round pin 283 from the image information storage unit 120, and displays the pop-up corresponding to the round pin 283. A thumbnail image of the image information is displayed in the window image. For example, the display unit 208 displays a thumbnail image in a pop-up window image 284, for example, as in a display screen 280 shown in FIG.

  If the thumbnail image column of the image information storage unit 120 is “None” for the image information of the shooting position corresponding to the selected round pin 283, the image generation unit 114 Either do not display the window, or display the absence of an image in a popup window. When image data of the main image exists, the image generation unit 114 may generate a thumbnail image based on the image data of the main image and display the thumbnail image on the display unit 208.

  When the thumbnail image is displayed, in step S311, the point information storage unit 124 gives a predetermined point to the device ID corresponding to the thumbnail image. The points may be given to the user ID. In this case, when the attribute of the information viewer 200 is a person related to the news media, a higher point may be given as compared with the case where the attribute is not the case. When the ID of the information provider 301 and the ID of the information viewer 200 are the same, points need not be given.

  Subsequently, in step S312, the image generation unit 114 determines whether one of the round pins 282 is selected by the information viewer 200 and a request to display a main image corresponding to the round pin 282 is made. If it is determined that the display of the main image has been requested, the main image is displayed based on the main image data, and the process proceeds to step S313. If the display of the main image has not been requested for a predetermined period, the process proceeds to step S314.

  In step S312, the image generation unit 114 determines that the display of the main image has been requested when the mouse cursor is positioned on the selected round pin 283 and double-clicked. When determining that the display of the main image has been requested, the image generation unit 114 refers to the image information storage unit 120 and causes the display unit 208 to display the main image corresponding to the round pin 282 instead of the map image 281. . As a result, as shown in FIG. 16, for example, an image 291 indicating the case object 292 provided by the information provider 300 or the like is displayed on the display unit 208. Here, when the image field of the image information storage unit 120 is “None”, the image generation unit 114 does not shift to the display screen 290 or displays in the display screen 290 that there is no image. .

  In step S313, when an image is displayed by the selection of the information viewer 200, the image generation unit 114 assigns a predetermined point to the device ID corresponding to the image as in step S311, and proceeds to step S314. move on. In this case, the point for the thumbnail image may be higher than the point for the thumbnail image. Further, when the attribute of the information viewer 200 is a person related to the news media, a higher point may be given as compared with the case where the attribute is not the case. When the ID of the information provider 301 and the ID of the information viewer 200 are the same, points need not be given. After the display screen 290 is displayed in step S312, if the check box 220 is clicked, the process returns to step S309 and switches to the display screen 280.

  In step S314, measuring unit 110 determines whether display update button 223 has been selected by information viewer 200 or not. If it is determined that the display update button 223 has been selected, the process proceeds to S304, and the measuring unit 110 measures the image information under the set search conditions. The display unit 208 instructs the measurement unit 110 via the image generation unit 114 that the display update button has been selected. Upon receiving the instruction, the measuring unit 110 determines that the display update button 223 has been selected, and in step S304, measures the image information again under the set search conditions. On the other hand, if it is determined that the display update button 223 has not been selected, the process proceeds to step S315.

  In step S315, the measurement unit 110 determines whether the elapsed time from the previous measurement has exceeded the set synchronization interval. In this case, the measuring unit 110 reads out the synchronization time from the search information storage unit 122. If the measuring unit 110 determines that the elapsed time has exceeded the synchronization interval, the process proceeds to step S304, and measures the image information again under the set search conditions. On the other hand, when it is determined that the elapsed time from the previous measurement has not exceeded the synchronization interval, the process proceeds to step S316.

  In step S316, the information processing device 100 determines whether the end button 225 on the display screen 280 has been selected. If it is determined that the end button 225 has not been selected, the process proceeds to S306. When the display unit 208 determines that the end button 225 has been selected, the operation flow ends.

  In connection with the measurement processing in step S304, a case has been described in which the measurement unit 110 measures the number of pieces of image information in a mesh area obtained by dividing a map by a mesh of a specific distance. Instead, the measuring unit 110 measures the density of image information per time from the number of image information and position information within a specific period, and the notifying unit 112 sets the density and the information viewer 200 to set the density. May be compared with the threshold value.

  Although the case where a thumbnail image is displayed on the popup window image 284 in step S309 has been described, image information such as altitude information and azimuth information may be displayed together with the thumbnail image. In addition, when the round pin 282 is continuously selected for a predetermined period, the thumbnail image may be automatically displayed, and another operation may be added to display the thumbnail image.

  In the above description, the mode in which the information processing apparatus 100 holds the search information has been described. However, the terminal 202 may hold at least a part of the search information. As an example, a case where the terminal 202 holds all search information will be described. The terminal 202 holds the search information described with reference to FIG. 6A except for the information of the device ID. The terminal 202 transmits the search condition included in the search information to the information processing device 100 every time the synchronization interval elapses. The information processing apparatus 100 searches for image information that satisfies the search condition received from the terminal 202. The information processing apparatus 100 displays, for example, the display screen 275 of FIG. 14 on the display unit 208 according to the search result of the image information. When the search condition is changed by the information viewer 200, the terminal 202 holds the changed search condition. The terminal 202 can acquire the result based on the new search condition from the information processing device 100 by transmitting the changed search condition to the information processing device 100 at the timing when the synchronization interval has elapsed.

  In the operation according to FIG. 13, the process in which the information processing apparatus 100 notifies that the number of image information satisfying the search condition exceeds the threshold when the terminal 202 executes the information browsing program. As described above, the information processing apparatus 100 also notifies by e-mail that the number of image information satisfying the search condition has exceeded the threshold. Here, the notification process by e-mail will be described. The search information used for notification by e-mail is based on the alarm data described with reference to FIG. 6B. As described above, the alarm data described with reference to FIG. 6B is set by the operation described with reference to FIG. 9 and FIG.

  The search condition for the alarm is determined by the search target period, the size and the threshold value of the area described with reference to FIG. 6B, and the measurement method and the area described with reference to FIG. 6A. That is, with respect to the search target period, the size of the area, and the threshold, a condition different from the search condition described with reference to FIG. 6A can be set as the search condition for the alarm. The alarm measurement operation in the information processing apparatus 100 is performed every time the synchronization interval described with reference to FIG. 6A elapses.

  The alarm measurement operation in the information processing apparatus 100 is performed every time the synchronization interval described with reference to FIG. 6A elapses. The same processing as the measurement processing described in relation to step S304 in FIG. 13 can be applied to the alarm measurement processing in the measurement unit 110. That is, similar to the measurement processing described in relation to step S304 in FIG. 13, except that the search conditions regarding the search target period, the size of the area, and the threshold are determined based on the information described in relation to FIG. 6B. Can be applied.
