<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the log display device according to the present embodiment. Note that the functional blocks of the apparatus described below can be realized by cooperation of computer (computer) software and hardware resources. Specifically, a computer's hardware resources, such as a CPU, main memory, bus, or secondary storage device (hard disk, nonvolatile memory, storage medium such as a CD or DVD, and a read drive for these media), information input Input devices, printers, display devices, other external peripheral devices, etc., interfaces for external peripheral devices, communication interfaces, driver programs and application programs for controlling these hardware, user interfaces Application programs.

  Then, the data read from the secondary storage device and loaded into the main memory and processed by the CPU according to the program is processed and accumulated from the input device and other interfaces and the data held on the memory and hard disk. Or, an instruction for controlling the hardware or software is generated. Alternatively, the functional block of the log display device may be realized by dedicated hardware. Further, the program for operating the general-purpose computer or the dedicated hardware may be realized as a plurality of modularized programs, or may be realized as a single program by combining two or more programs.

  In addition, this embodiment can be realized not only as an apparatus but also as a method. Also, some of the functions of such an apparatus can be configured as software. Furthermore, a software product used for causing the computer to execute such software and a recording medium on which the product is fixed are naturally included in the technical scope (the same applies throughout the present specification).

  As shown in FIG. 2, the “log display device” (0200) of this embodiment includes a “content acquisition unit” (0201), a “content display unit” (0202), and a “display control unit” ( 0203), a “selection unit” (0204), and a “map display unit” (0205).

  The “content acquisition unit” (0201) has a function of acquiring a plurality of contents associated with a position and time, and is realized by, for example, a CPU, a main memory, an I / O (input / output), a content acquisition program, or the like. be able to.

  FIG. 3 is a conceptual diagram for explaining an example of content acquired by the content acquisition unit. As shown in this figure, for example, the content identified by the content ID: P001 is an image photographed by the camera, and is associated with the photographing position and photographing time information acquired by the GPS function and the clock function of the camera. . In addition, the content identified by the content ID: T001 is article data posted to the short text posting service, and is associated with position information related to the article target and time information of uploading the article to the site web server. It is. As described above, the content acquired by the content acquisition unit is associated with date / time information related to creation, acquisition, update, and the like, and the type of content is not limited as long as it is displayed on a display or the like.

  For example, the content acquisition unit acquires image data content from a recording device or acquires article text data content from a web server of a site that provides a short text posting service via a network.

  The number of contents acquired by the content acquisition unit is not particularly limited. For example, all the contents received by the content distribution server (in the above example, the web server of the posted article) within a certain period such as one day are received. It is good also as a structure to acquire. Alternatively, if the number of contents to be distributed / acquired at a time is set in advance by a content distribution program executed by the content distribution server or a content acquisition program executed by the log display device The configuration may be such that the set number is acquired.

  The “content display unit” (0202) has a function of displaying all or a part of the acquired content in a time sequence and displaying it on the screen, and is realized by, for example, a CPU, a main memory, a VRAM, a display device, a content display program, or the like. be able to.

  FIG. 4 is a diagram illustrating an example of a display image by the content display unit. Here, the content is article text data uploaded to the web server of the short text posting service site, and the number of acquisitions is ten. In the log display device according to the present embodiment, as shown in FIG. 4, three pieces of article text data are displayed side by side in order of the uploaded date and time. In addition, this figure shows an example in which a map display area by a map display unit described later is arranged on the same screen as this content display area, but the display mode of the map and the content is not limited thereto, A mode in which the map and the content are displayed on different screens such as displaying on the television screen and displaying the other on the mobile terminal screen may be possible.

  The “display control unit” (0203) has a function of controlling the operation of the content display unit (0202) so that a plurality of contents are simultaneously scrolled and displayed according to an operation. For example, a CPU, a main memory, It can be realized by a VRAM, a display device, a display control program, or the like.

  FIG. 5 is a diagram for explaining an example of scroll display of content by the display control unit. As shown in FIG. 5A, the article text data 1-3, which is the content, is displayed on the screen. Here, for example, when a touch screen is provided as an input device, when the user touches the screen with a finger and performs an upward tracing operation as indicated by an arrow, a signal indicating the tracing operation is output from the touch screen, and the output signal is output. As shown in FIG. 5B, a scrolling display in which each text data moves upward is performed by display control according to the above. Then, each text data is moved by the scroll amount corresponding to the tracing amount detected by the touch screen, and the text data 4-6 is displayed on the screen. The content of the operation for scroll display is not particularly limited, and includes, for example, the touch screen touch operation, the up / down / left / right key operation for instructing the scroll direction using a keyboard or a controller, and the operation using a mouse pointer. May be.

  “Content scroll display” refers to display by transition of content, and the transition amount changes according to the input operation amount. Therefore, the user can scroll-display a plurality of contents so as to achieve a desired transition amount by performing an operation that achieves a desired operation amount.

  Further, in the scroll display of content, “loop display” may be performed. In other words, when a scroll operation in the direction of returning the time is input in a state where the oldest content is displayed in time order by scroll display, the newest content in time order is displayed in the form of arranging next to the oldest content. (Or the oldest content is displayed next to the newest content in time order) may be displayed.

  The “selection unit” (0204) has a function of selecting a part of the content on the screen to be scrolled and can be realized by, for example, a CPU, a main memory, a selection program, and the like.

  FIG. 6 is a conceptual diagram for explaining an example of the selection process in the selection unit. As shown in FIG. 6, for example, a setting is made in advance so that the top content is selected from the content that is displayed side by side in the vertical direction in the screen by the processing of the content display unit. Then, the content arranged in the selection area (thick line frame in the figure) is selected by scrolling according to the operation. As shown in FIG. 6 and other figures, the selection area may be displayed on a screen with a thick frame so that the user can identify where the selection area is. Alternatively, the selection area may not be displayed on the screen so that the user can identify it, but the area may be set only to be used in an internal process for selecting content.

  In the case of adopting the selection configuration as described above, the content displayed in the selection area is not selected when scrolling at a predetermined speed or higher, and the content displayed in the selection area is selected only when scrolling at a predetermined speed or lower. May be. Thus, the user can display the position of the desired content on the map as will be described later by adjusting the speed of the scroll operation.

  In some cases, a part of each of two adjacent contents (for example, the upper half of one content and the lower half of another content) are simultaneously arranged in the selection area. In such a case, there is no particular limitation on the process of determining which content is to be selected. For example, the method of processing the larger occupied area as the content to be selected, or selecting the newer associated time Examples include a method of making a target, or a method of virtually setting a specific point or line in a selection area and making content including the point or line a selection target.

  As described above, in the log display device according to the present embodiment, the content on the screen is not specified by, for example, a mouse pointer or a cursor that can be operated in response to a user input different from the content scroll display operation. By providing a fixed selection area or the like in the content display area, content is selected in conjunction with scroll display. By adopting such a configuration, the user does not check the contents one by one, but specifies the contents whose position is to be displayed on the map as described later while browsing the scrolled contents. Is possible.

  The “map display unit” (0205) has a function of displaying a position associated with the selected content on a map, and can be realized by, for example, a CPU, a main memory, a VRAM, a display device, a map display program, or the like. it can.

  FIG. 7 is a diagram illustrating an example of a map image by the map display unit. As shown in FIG. 7A, a map is displayed on the left side in one screen, and a plurality of contents are displayed side by side on the right side. Then, for example, an icon indicating the position related to the content selected by the selection unit is displayed on the map. Then, the contents arranged in time order by the scroll display unit are scroll-displayed, and when another content is selected, the position related to the other content is displayed on the map.

  The display of the related position of the content may be various in addition to the display using the icon as described above, for example, a form displayed by an arrow extending from the selected content as shown in FIG.

  By such position display on the map, the user scrolls the contents displayed in the screen in a time-series order and displays the position related to the display contents on the map by “looking while”. Can be confirmed.

  The map display unit may further have the following functions. As the function, for example, there is a function of displaying, on the map, a position associated with a content associated with a past time from a time attached to the selected content.

  FIG. 8 is a diagram illustrating an example of display by this function. As shown in FIG. 8A, the content 4 is selected by, for example, a scroll operation. Then, the position related to the content 4 is displayed as an icon (star) on the map, and the positions of the contents of the contents 1 to 3 associated with the past time are similarly (or selected content). It is displayed with an icon distinguishable from the 4 icon). Further, when a scroll operation in the direction going back from here is input and the content 2 is selected, the icon display of the content 3 and 4 previously displayed is cancelled, and is shown in FIG. 8B. Thus, the positions of the icons 1 and 2 are displayed.

  As described above, since the above function can display the locus of the position change according to the time of the content on the map, the user scrolls the plurality of arranged contents to the position of the displayed content. You can check the route.

  As another function of the map display unit, for example, when content acquired by the content acquisition unit includes content associated with the user ID, the position associated with the content selected by the selection unit is displayed on the map. There is also a function of displaying by user when displaying.

  FIG. 9 is a diagram illustrating an example of a display image by this function. As shown in this figure, for example, the content display area is divided into two columns A and B, and the contents of two users are displayed for each user. Regarding the position display on the map, for example, the selection of the content displayed in A is indicated by a solid star icon (★), and the selection of the content displayed in B is indicated by a white star icon. It is indicated by (☆).

<Hardware configuration>
FIG. 10 is a schematic diagram illustrating an example of a hardware configuration when each functional requirement of the log display device is realized by a computer (computer). The operation of each hardware element in content scroll display and map position display processing will be described with reference to FIG.

  As shown in FIG. 10, the log display device includes a “CPU (central processing unit)” (1001) and a “main memory” (1002) for executing various arithmetic processes. In addition, “flash memory” (1003), which is a secondary storage device that stores various data including content, and a program in which an information processing procedure for realizing the functions of each unit described above is defined, a content display unit, and a map “VRAM” (1004) or “display” (1005) which is a display unit, “UI (user interface)” (1006) for accepting an operation input from the user, “content” for connecting to an external content distribution apparatus or the like. Communication circuit "(1007) and the like. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read from the “flash memory” to the “main memory”, and the “CPU” executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, when a start command for the log display device of the present embodiment is input via “UI”, first, “CPU” interprets a GUI display program (not shown), and displays a map display area and content. A GUI screen including an area to be displayed is displayed on the “display”. The map display area is determined based on the map information stored in the “flash memory” separately by the calculation processing of the “CPU” or the map information acquired from another computer via the “communication circuit”. Display the map. Subsequently, the “CPU” interprets the content acquisition program, and, for example, if the content to be acquired is related to a Web service such as a short posting text, according to the interpretation result, from the Web server of the service via the “communication circuit”. To get multiple short text content. Further, if the content is a captured image managed by a PC (personal computer) incorporating a log display device, a plurality of images are captured from a secondary recording device such as “flash memory” or “HDD” (not shown). Get image content. Then, the acquired plurality of contents are stored at addresses 1, 2,.

  Subsequently, the “CPU” interprets the content display program, and for all or a part of the content acquired according to the interpretation result, for example, time information indicated as additional information, etc. If it is an image content, the shooting date and time) is acquired. Then, the order information indicating the time order is managed in association with the content identification information. By default, the content with the rank information “1” is set first, the content with the rank information “2” is acquired, and then the content with the rank information “3” is acquired. The drawing process for “VRAM” is performed so that the content is displayed in the content display area. In this way, for example, three contents arranged in order of time are displayed in the content display area of the “display”.

  Subsequently, the “CPU” interprets the selection program, determines that, for example, the top of the current content display area is set as the selection area according to the interpretation result, and the content displayed in the same area is selected. Shall be. Then, the “CPU” interprets the map display program, and for the selected content, for example, the associated position (in the case of short text text content, the post position or the article target in the short text) indicated by the additional information or the management table. Latitude / longitude information indicating the position and the shooting position of the captured image content is acquired and stored in address 3 of the “main memory”. Then, on the map displayed in the map display area of the “display”, the position corresponding to the latitude / longitude information is specified by the calculation processing of the “CPU”, and an icon or the like is drawn and displayed at the position.

  Thereafter, when an operation command indicating scroll display of content is input from the user via the “UI”, the “CPU” interprets the display control program. Then, according to the interpretation result, the scroll operation information indicating the input scroll direction, scroll amount, and scroll speed is acquired and stored in addresses 4... Of “main memory”. Subsequently, according to the acquired scroll direction, scroll amount, and scroll speed, an animation is drawn in the “VRAM” so that the displayed contents are simultaneously moved and scroll-displayed.

  In this way, for example, if the scroll amount is two contents, the contents displayed at the top and the next (contents of ranks “1” and “2”) protrude to the upper direction of the screen and disappear. , The content of the ranking “3” is moved to the top of the content display area and displayed, and the “CPU” refers to the ranking information described above, and the content of the ranking information “4” and the content of the ranking information “5”. Are arranged in order from the bottom of the screen, and are displayed in the content display area by moving and displaying them in an upward direction.

  In addition, because of the scroll display, the content of the rank “3” is displayed in the selection area (the uppermost area of the content display area). Therefore, “CPU” is ranked according to the interpretation result of the selection program. 3 ”is selected. Then, as described above, the “CPU” interprets the map display program, acquires latitude / longitude information indicating the position associated with the content of the selected rank “3”, and displays the position corresponding to the latitude / longitude information on the map. It is displayed with an icon or the like.

  Here, in the above description, each of the above programs is read from the “flash memory” to the “main memory”, and the “CPU” executes the display process according to each program. Each program may be acquired from the above and similar processing may be realized. Specifically, a browser (software program for browsing content on the Internet) is expanded from “flash memory” to “main memory”, and “CPU” follows content from a server on the network via a “communication circuit” according to the browser. The command document data (for example, html data) including the content is displayed and the content is displayed, and further, the program (for example, the script program) described to be called from the server and used by the command document data is acquired. Then, it may be configured to execute each process related to the display according to the scroll operation by storing in the “main memory” and executing the interpretation.

<Process flow>
FIG. 11 is a flowchart illustrating an example of a processing flow in the log display device according to the present embodiment. Each step shown below shows the processing procedure of the log display method by the log display device, but is defined as a program for controlling the computer when the log display device is realized by a computer as described above. The process steps shown are also shown.

  As shown in FIG. 11, first, when a plurality of contents associated with the position and time are acquired (step S1101), all or a part of the acquired contents are arranged in time order and displayed on the screen (step S1102).

  When an input of a scroll operation is received (step S1103), a plurality of contents to be displayed on the screen are controlled to be simultaneously scrolled and displayed according to the received operation (step S1104). Then, a part of the content in the screen to be scrolled is selected (step S1105), and the position associated with the selected content is displayed on the map (step S1106).

<Brief description of effect>
As described above, with the log display device according to the present embodiment, a plurality of contents arranged in time order and displayed on the screen are scroll-displayed, and contents displayed in a predetermined screen area among the scroll-displayed contents are displayed. The position can be displayed on the map.

  Therefore, according to the log display device, the log display method, or the program of the present embodiment, the user does not check the contents one by one, but displays the contents while browsing a plurality of contents by so-called “watching”. It is possible to confirm the position on the map regarding the content that has been made.

<Other configuration>
Further, in the above-described embodiment, an example is described in which each process is executed as a component requirement of the log display device. May be executed. In this case, for example, the log display device acquires the content provided from the server or another content distribution server by the “content acquisition unit” and performs the processing of the “content display unit” realized by, for example, an Internet browser or the like. Display the content. When a scroll operation from the user is accepted, scroll operation information indicating the scroll amount and scroll direction is transmitted to the server. Then, the server receives the scroll operation information, executes a process related to the “display control unit” accordingly, and outputs a control command for controlling the content display unit of the log display device. Further, the server executes processing related to the “selection unit” according to the scroll operation information, and is displayed in the selection area of the screen among the contents displayed on the terminal by the control instruction of the output content display unit. Identify the content that will be.

  And according to the specific result, the control command for displaying the position concerning the content on the map of the terminal is generated and transmitted to the terminal. Then, the terminal that has received the control command executes the function of the “map display unit” realized by, for example, an Internet browser and displays the position related to the content on the map.

<< Example 2 >>
<Overview>
The log display device according to the present embodiment is based on the first embodiment and further includes the following functions. That is, it is assumed that ten contents 1 to 10 are acquired in the log display device of the present embodiment, and three of the contents are displayed on the screen side by side in the order of time. Then, according to the scroll display operation input from the user, as shown in FIG. 12A, the contents 8 to 10 including the last contents 10 in time series are displayed on the screen.

  When the selection area remains set at the top of the content display area (thick line frame α in FIG. 12A), the selection unit of the log display device according to the present embodiment displays the contents 9 and 10 in this display state. Cannot be selected. Therefore, in the log display device according to the present embodiment, when content scroll display can no longer be performed as described above, when an input of a further scroll operation is received, instead of scrolling the content accordingly, for example, FIG. As shown in (b), the content 9 and 10 can be selected by performing a process of moving the selection area α.

<Functional configuration>
FIG. 13 is a diagram illustrating an example of functional blocks in the log display device according to the present embodiment. As shown in this figure, the “log display device” (1300) of the present embodiment is based on the first embodiment and includes “content acquisition unit” (1301), “content display unit” (1302), and “display”. A "control unit" (1303), a "selection unit" (1304), and a "map display unit" (1305).

  In the log display device according to the present embodiment, the selection unit further includes a “scroll end determination unit” (1306) and a “selection change unit” (1307).

  "Scroll end determination means" (1306) has a function of determining whether the first or last content in time order is displayed on the content display unit and scroll display according to the operation can no longer be performed. For example, it can be realized by a CPU, a main memory, a scroll end determination program, or the like.

  Specifically, the processing contents such as the content display program described in the first embodiment are monitored (or a notification is received from the program), and the oldest content is displayed in a time-series order by scroll display. When a scroll operation in the direction going back is input, or when a scroll operation in the direction of advancing the time in the state where the latest content is displayed in chronological order, the scroll display can no longer be performed. The determination result is output. In this embodiment, it is assumed that the above-described loop display (a form in which the first and last contents are connected and displayed in time order) is not performed.

  The “selection changing unit” (1307) changes the content to be selected according to the operation when the determination result by the scroll end determination unit (1306) is a determination result that the scroll display of the content can no longer be performed. For example, it can be realized by a CPU, a main memory, a selection change program, and the like.

  Specifically, if the result is that the oldest content is displayed in chronological order and it is determined that scrolling can no longer be performed, and if a scroll operation in the direction going back in time is further input, In accordance with the scroll amount, content that is older (returned) by the scroll amount in time series order is selected. Or, if the result is that it is no longer possible to perform scroll display with the most recent content displayed in chronological order, if a scroll operation in the direction of further time advance is input, depending on the scroll amount Thus, the new (advanced) content is selected by moving the selection area α by the scroll amount in chronological order.
