Switch to (second thumbnail) (FIG. 3). In the screen example of FIG. 3, the file K is switched to the second thumbnail generated from the second page, and the files R and T are switched to the second thumbnail generated from the third page.

<Functional configuration>
FIG. 4 is a block diagram illustrating a specific example of a functional configuration of the server 100 for realizing the display of the thumbnail. Each function of FIG. 4 is mainly realized by the CPU 10 when the CPU 10 of the server 100 reads a program stored in the ROM 11 onto the RAM 12 and executes the program. However, at least a part of the functions may be realized by a hardware configuration such as the device configuration shown in FIG. 1 or an electric circuit (not shown).

  Referring to FIG. 4, a memory such as HDD 13 of server 100 is a content file storage unit 131 that is a storage area for storing content files, and a storage area for storing measurement data of feature amounts described later. And a feature amount storage unit 132. Further, referring to FIG. 4, the CPU 10 passes a thumbnail of the file in the folder designated from the terminal device 300 to the terminal device 300 via the network controller 15 and displays it on the touch panel 33. A creation unit 102 for creating a thumbnail from a feature region of a file, and an extraction unit for extracting a feature region, which is a region for creating a thumbnail from a file, with reference to stored feature amount measurement data 103, a feature amount acquisition unit 104 for acquiring a feature amount of a file, which will be described later, for each parameter, and a first thumbnail displayed on the terminal device 300, which is a display device, to switch to the second thumbnail Parameters from the terminal device 300 via the switching unit 105 and the network controller 15 Includes a selection unit 106 for accepting a selection, and a detector 107 for detecting the viewing status of the terminal device 300 is a display device by a user.

  FIG. 5 is a diagram illustrating a specific example of the feature amount related to a certain file stored in the memory. As parameters, the average time that the file was displayed (average stay time), the total number of consents obtained for the file (number of times agreed, total consent, etc.), and the number of writes made to the file ( (Total number of annotations), the number of times the file has been introduced or its contents (quoted information), etc. are set, and the value is called a feature amount. Other examples of parameters include, for example, the number of appearances of a keyword, the number of characters of a specific color, the number of times a specific operation (enlargement, etc.) has been performed, and the like.

  The feature amount acquisition unit 104 of the server 100 acquires feature amounts for these parameters for each region (for example, page) of the file. For example, regarding the average display time, the feature amount acquisition unit 104 measures the display time for the user for each area of the file, and acquires the feature amount by calculating the average time. Regarding the total number of consents, the feature quantity acquisition unit 104 monitors whether or not consent has been added for each area of the file, and acquires the feature quantity by measuring the number of consents.

  The area may be the entire file or a part of the file. Further, it may be an entire arbitrary page constituting the file, or may be a specific area in the page. The feature amount acquisition unit 104 acquires a feature amount for each file and accumulates the acquired feature amount in a memory. FIG. 5 shows the acquired feature amount for a certain file. Therefore, the feature quantity as shown in FIG. 5 is stored for each file in the memory of the server 100.

  The feature amount acquisition unit 104 may further acquire a feature amount for each user or each user group. In that case, the feature amount as shown in FIG. 5 is stored for each user.

  The extraction unit 103 reads the feature amount of each file to be displayed as a thumbnail, and refers to the feature amount for the selected parameter. Then, an area in which the feature amount satisfies a predetermined condition in the file is extracted as a feature area for creating a thumbnail. Examples of the predetermined condition include that the feature amount is maximum, minimum, and closest to the average value. Further, the extraction unit 103 may read a feature amount for a specific user (for example, a login user).

  In addition to the feature amount (or together with the feature amount), an area that is not a thumbnail, that is, an area that is not a feature area may be set for each file. In this case, the extraction unit 103 extracts a feature region from a range where this setting is not made in the file.

  The creation unit 102 creates a thumbnail from the feature area. As a general creation method, there is a method of reducing the feature region to a predetermined size, but it is not limited to this method. Further, the creation unit 102 may create, for example, information representing the transfer source of the file as additional information with reference to the attribute of the file and add it to the thumbnail. Additional information includes the photo and name of the introducer of the file. The creation unit 102 may create such additional information and add it to the thumbnail only for a file that has not been browsed by the user.

<Operation flow>
FIG. 6 is a flowchart showing an operation flow in the server 100 according to the first embodiment. 6 is realized by the CPU 10 of the server 100 reading out and executing the program stored in the ROM 11 on the RAM 12 and performing the functions shown in FIG. The operation of FIG. 6 is started when a folder is designated from the terminal device 300.

  Referring to FIG. 6, CPU 10 of server 100 displays a predetermined default thumbnail, which is a first thumbnail, on terminal device 300 for each file stored in a designated folder (step S300). S101). In the example screen shown in FIG. 2, a thumbnail created in advance as a feature area for the first page of each file (ie, a thumbnail for one page) is displayed as a default.

  After that, when the parameter button in the screen example of FIG. 2 is touched to accept selection of a parameter from the terminal device 300 (YES in step S103), the CPU 10 switches the first thumbnail to the second thumbnail ( Step S105). In step S105, in detail, the CPU 10 reads out the feature amount for the parameter selected from the feature amount of each file, and specifies the region where the feature amount satisfies a predetermined condition (for example, the largest) as the feature region ( Step S107). Then, the CPU 30 creates a second thumbnail from the feature area (step S109) and displays it on the terminal device 300 (step S111).

  With the above operation, the default thumbnail that is the first thumbnail displayed in the screen example of FIG. 2 is switched to the second thumbnail in the screen example of FIG. Furthermore, since the server 100 continues to acquire the feature amount for each file, the feature amount changes depending on the usage status (display, etc.) of the user's file. Therefore, depending on the subsequent operation in the server 100, the thumbnail may be switched to the second thumbnail as shown in FIG. In the screen example of FIG. 7, the predetermined area of the fifth page of the file J is specified as the characteristic area, and is switched to the second thumbnail created therefrom.

<Effect of the first embodiment>
By performing the above-described operation in the server 100, the default thumbnail is switched to a thumbnail according to the tendency of the parameter by selecting a parameter representing an item that the user wants to use for file identification. This makes it easier for the user to identify files with thumbnails.

  Furthermore, since the server 100 continues to acquire the feature amount of the file for each parameter, as the user continues to use the display system, an area that can be easily identified by the user is presented as a thumbnail. Accordingly, it is possible to flexibly respond to the user's needs and display a more convenient file list or a thumbnail that serves as a preview of file components.

[Second Embodiment]
<Overview of operation>
The display system according to the second embodiment detects the browsing status of the terminal device 300. The browsing status includes, for example, a user who is browsing the terminal device 300 that is a display device, a viewing direction that is a direction toward the touch panel 33 of the user, a distance to the user, similarity of the first thumbnail, and the like. Can be mentioned. The display system switches the first thumbnail to the second thumbnail according to the browsing situation detected after the display of the first thumbnail.

<Functional configuration>
The terminal device 300 may include a sensor (not shown) such as a camera, a fingerprint sensor, and a microphone for detecting the browsing state. The detection unit 107 of the server 100 acquires detection information such as a photographed image and sound from the terminal device 300 via the network controller 15 and detects the browsing status based on the detection information. For example, the detection unit 107 identifies a user who is browsing by analyzing a captured image, or identifies a user who is browsing by comparing a sensor signal from a fingerprint sensor with pre-stored fingerprint data. Or you may. Moreover, the detection part 107 may acquire the login information to the said terminal device 300 from the terminal device 300, and may specify the user who is browsing based on the login information.

  Other browsing situations such as the viewing direction and the distance to the user can be detected in the same way. That is, the distance to the user may be detected by the terminal device 300 mounted with a general distance sensor (not shown) and the detection unit 107 may detect the distance based on the sensor signal from the sensor. Also, the terminal device 300 is equipped with one or two cameras (not shown), and the detection unit 107 analyzes a captured image from the camera (or camera group) and measures the size of the captured user. It may be detected.

  The switching unit 105 switches to the second thumbnail according to the detection result from the detection unit 107 after the display of the first thumbnail.

<Operation flow>
FIG. 8 is a flowchart showing an operation flow in the server 100 according to the second embodiment. The operation shown in the flowchart of FIG. 8 is also realized by the CPU 10 of the server 100 reading out and executing the program stored in the ROM 11 on the RAM 12 and exhibiting the functions of FIG. The operation of FIG. 8 is also started when a folder is designated from the terminal device 300. FIG. 8 shows an operation in the case of detecting a user who is browsing as a browsing situation.

  Referring to FIG. 8, CPU 10 of server 100 displays a predetermined default thumbnail, which is a first thumbnail, on terminal device 300 for each file stored in a designated folder (step S300). S201).

  After displaying the first thumbnail, the CPU 10 detects a user who is browsing the terminal device 300 based on information acquired from the terminal device 300. As this method, for example, a method of detecting a user who is browsing by acquiring login information from the terminal device 300 and specifying a logged-in user may be used. Alternatively, a method may be used in which a photographed image is acquired from the terminal device 300 and a user browsing the image is detected by performing a matching process using a pre-registered user's photograph as a template.

  When the browsing user is detected (YES in step S203), the CPU 10 switches the first thumbnail to the second thumbnail (step S205). More specifically, in step S205, the CPU 10 reads out the feature amount acquired for the user from the memory (step S207), and specifies a feature region based on the feature amount (step S209). At this time, the parameter used for extracting the feature region may be set in advance for each user, or the selection of the parameter may be received from the browsing user as in the first embodiment. . The CPU 10 creates a second thumbnail from the identified feature area (step S211) and displays it on the terminal device 300 (step S213).

  In step S203, as another example of the browsing situation, a browsing direction that is a direction toward the touch panel 33 of the user may be detected. In this case, the CPU 10 creates a second thumbnail from the feature area specified from the feature amount, and displays it in the viewing direction, that is, toward the user. As another example of the browsing situation, a distance to the browsing user may be detected. In this case, the CPU 10 creates a second thumbnail from the feature area specified from the feature amount, and displays it with a size corresponding to the distance. That is, when the detected distance of the user to the terminal device 300 is smaller than the specified distance (the user is near), the CPU 10 makes the thumbnail smaller than the specified size, and the distance of the user to the terminal device 300 is specified. If it is larger than the distance (the user is far away), the thumbnail may be displayed larger than the specified size.

<Effects of Second Embodiment>
With the above operation, the default thumbnail that is the first thumbnail displayed in the screen example of FIG. 2 is switched to the second thumbnail according to the browsing status by the user. As a result, it is possible to flexibly meet the user's needs and display a more convenient thumbnail.

[Third Embodiment]
As a third embodiment, the display system may switch to the second thumbnail by combining the detection results of the browsing status of a plurality of items. For example, when a plurality of browsing users are detected, the browsing direction of each user may be further detected, and the first thumbnail may be switched to the second thumbnail according to the detection result.

  FIG. 9 is a flowchart showing an operation flow in the server 100 according to the third embodiment. The difference from FIG. 8 will be mainly described. That is, referring to FIG. 9, in the third embodiment, when a browsing user is detected (YES in step S203), CPU 10 further detects the browsing direction of each user (step S204). Then, the CPU 10 switches the first thumbnail to the second thumbnail according to these detection results (step S205). In this case, when the CPU 10 creates the second thumbnail in step S <b> 211 in step S <b> 205, the display direction is converted according to the detected viewing direction (step S <b> 212) and is displayed in step S <b> 213.

  FIG. 10 and FIG. 11 are diagrams showing display examples in the third embodiment. Each figure shows a display example of the second thumbnail when three users are detected as browsing situations after the display of the first thumbnail. In the case of FIG. 10, three users are in the same direction with respect to the terminal device 300 and the viewing direction is detected as the same direction. In this case, the CPU 10 displays the second thumbnail for each user in the same direction. At this time, as shown in FIG. 10, the CPU 10 displays one when the second thumbnails for the same file are common (that is, when the feature areas are the same), and displays them differently when they are different. Also good. In addition, the size of the second thumbnail may be changed depending on the presence / absence of login, the detected order, and the like.

  In the case of FIG. 11, one of the three users is located on the opposite side with respect to the terminal device 300 and the viewing direction is detected as the opposite direction. In this case, the CPU 10 displays the second thumbnail for each user in each viewing direction. At this time, as shown in FIG. 11, when the second thumbnails for the same file are common (that is, when the feature areas are the same), the CPU 10 sets the viewing direction to 1 in the direction with many users. Only when the second thumbnails are different, they may be displayed according to the viewing direction.

<Effect of the third embodiment>
With the above operation, the default thumbnail that is the first thumbnail displayed in the screen example of FIG. 2 is switched to the second thumbnail depending on the viewing status by the user. Thereby, it is possible to respond flexibly to the needs of the user, and it is possible to display a more convenient thumbnail.

  In this case, the function for the CPU 10 to acquire the feature value is realized by a CPU included in a second recording device (not shown), and the server 100 refers to or acquires the feature value acquired as a result. Also good. Alternatively, the function for acquiring the feature amount is realized by a CPU included in another processing device (not shown) that does not store the content file, which is further different from the server 100 and the second recording device. Also good. Furthermore, the CPU 30 of the terminal device 300 may be realized.

  In other words, when a list of files and a preview of file components are previewed by the terminal device 300 between devices connected via a network regardless of wired or wireless, they are stored in a location accessible from the terminal device 300. As long as the list of thumbnails can be displayed based on the feature amount so far, the functions realized by each device are not limited to the above description. That is, the functions shown in FIG. 4 such as the feature amount storage unit 132, the content file storage unit 131, the creation unit 102, the extraction unit 103, the feature amount acquisition unit 104, and the switching unit 105 are realized by any device.
