  The imaging unit 12 may be built in the terminal 10 or may be a connectable external device. When the imaging unit 12 is mounted, it is preferable that the tilt, the direction, and the like are operated integrally with the terminal 10, but the present invention is not limited to this.

  In addition, the imaging unit 12 performs analysis of feature amounts such as a face and eyes on the acquired image, and acquires, for example, how many regions in the image correspond to the eye features. In the present embodiment, the eye gaze direction, feature quantities other than the eyes (for example, the number and orientation of faces), and the like may be acquired.

  The display unit 13 displays, for example, information (public information) that can be disclosed to third parties such as customers and others, and information that is confidential and cannot be disclosed (confidential information, non-public information). Note that the confidential information (non-public information) is an example of information that is subject to non-display control. The information that is the target of non-display control may be, for example, information including confidential information or the like, or may be other preset information.

  The display unit 13 displays a screen on which confidential information or the like is not displayed by the display control unit 17. Further, the display unit 13 displays a preset menu screen, setting screen, operation screen for operating the terminal 10 and the like in order to perform display control processing in the present embodiment. The display unit 13 may input information from the screen like a touch panel.

<Example of display control processing>
Next, an example of display control processing in the present embodiment will be described using a flowchart.

<First embodiment>
FIG. 4 is a flowchart showing a first example of display control processing according to the present embodiment. In the example of FIG. 4, the control unit 18 of the terminal 10 activates an application that performs display control processing in the present embodiment, and reads display items displayed on the screen of the display unit 13 (S01).

  Next, the detection unit 15 detects the inclination of the terminal 10 (S02). Next, the determination unit 16 determines whether the inclination of the terminal 10 obtained by the detection unit 15 is equal to or greater than a threshold value (S03). The inclination threshold described above can be set in advance by a user or the like.

  When the inclination of the terminal 10 is equal to or greater than the threshold (YES in S03), the display item read in the process of S01 is compared with the confidential management data shown in FIG. The secret information set as private is hidden and displayed on the screen (S04).

  In the process of S03, when the inclination of the terminal 10 is not equal to or greater than the threshold (NO in S03), the imaging unit 12 captures an image of a predetermined area on the screen (S05). In the process of S05, the imaging unit 12 may perform image analysis, and obtain the number of eyes in the image by comparing with eye feature data set in advance. Next, the determination unit 16 determines whether or not the number (number) of eyes in the image is equal to or greater than a threshold value (S06). The above-mentioned threshold value for the number of eyes can be set in advance by a user or the like.

  If the number of eyes is not greater than or equal to the threshold (NO in S06), the display control unit 17 displays all of the read display items as they are on the screen (S07). In the process of S06, when the number of eyes is equal to or larger than the threshold (YES in S06), the process of S04 described above is performed.

  Next, it is determined whether or not to end the process (S08). If the process is not terminated (NO in S08), the process returns to S02. When the process is terminated by a user operation or the like (YES in S08), the display control process (application) in the first embodiment is terminated.

In the first embodiment described above, the control for hiding the secret information only by the tilt of the terminal 10 may be performed without performing the determination based on the number of eyes or the like. In the first embodiment described above, the display control unit 17 hides the confidential information, and then receives a predetermined operation such as setting the terminal 10 to the reference angle θ ₀ or touching the screen. Alternatively, the confidential information may be displayed again after a predetermined time has elapsed.

5 and 6 are diagrams (part 1 and part 2) for explaining the contents of the first embodiment. In the example of FIG. 5, the person in charge (user) 40 and the customer 41 refer to the screen of the terminal 10. In the first embodiment, as shown in FIGS. 5A and 5B, the display control unit 17 performs, for example, confidential information (inclination information (inclination θ ₁ from the reference angle θ ₀ )) according to the angle of the terminal 10. Control to switch display or non-display of information (items) set in advance in (non-public information) is performed.

For example, in the example of FIG. 5A, the person in charge 40 is browsing the information displayed on the screen with the terminal 10 standing vertically. Here, when the reference angle θ ₀ is the vertical direction, the inclination of the terminal 10 is not equal to or greater than the threshold θ ₁ . Moreover, when the threshold value of the number of eyes is set to 3 or more, the number of eyes is 2 in total, so that public information and non-public information (secret information) can be displayed.

Also, by tilting the terminal 10 threshold theta ₁ or more as shown in FIG. 5 (B), public information (confidential information) is hidden, only public information is displayed. In the example of FIG. 5B, even if the terminal tilt is less than θ ₁ , the left and right total is 4 for the person in charge 40 and the customer 41, so that the non-public information is not displayed. Become.

  In the example of FIGS. 6A and 6B, the determination unit 16 performs image analysis on the video (screen) 42 acquired by the camera (imaging unit 12) of the terminal 10, and determines the person appearing in the video. It is determined whether or not the number (number) of eyes is equal to or greater than a preset threshold (for example, 3). Note that the determination unit 16 may determine whether or not a plurality of persons are detected. For example, as shown in FIG. 6B, if the number of eyes is 3 or more, it can be determined that a plurality of persons are detected. Further, the display control unit 17 hides the confidential information by the object data 43 or the like according to the determination result.

  For example, in FIG. 6A, since the number of eyes shown in the camera image 42 is less than the threshold 3, business information as an example of confidential information is displayed on the screen of the display unit 13 as it is. In FIG. 6B, since the number of eyes shown in the camera image 42 is 3 or more, the object data 43 is superimposed or displayed on the screen of the display unit 13 of the terminal 10 from the business information. Switch images to display and not display (hide) business information. The object data can be acquired from the object management data shown in FIG. 3B described above, and the type of the object data 43 may be set for each display item. In addition, by determining based on the number of eyes, for example, as shown in FIG. 6B, even if one eye is detected, there is a possibility that confidential information may be browsed. It can be carried out.

<Second embodiment>
FIG. 7 is a flowchart showing a second example of the display control process in the present embodiment. In the example of FIG. 7, the control unit 18 of the terminal 10 activates an application that performs display control processing in the present embodiment, and reads display items displayed on the screen (S11).

  Next, the detection unit 15 detects the amount of movement of the terminal 10 (S12). The movement amount includes, for example, a distance at a predetermined time interval, a movement amount obtained from an acceleration sensor, and the like, but is not limited thereto. Next, the determination unit 16 determines whether or not the amount of movement of the terminal 10 obtained by the detection unit 15 is greater than or equal to the threshold (S13). If it is greater than or equal to the threshold (YES in S13), the process of S11 is performed. The read display item and the confidential management data shown in FIG. 3A are compared, and the confidential information set as private among the read display items is hidden and displayed on the screen (S14). .

  In the process of S13, when the movement amount of the terminal 10 is not equal to or greater than the threshold (NO in S13), the imaging unit 12 captures an image of a predetermined area on the screen (S15). In the process of S15, the imaging unit 12 may perform image analysis and obtain the number of eyes in the image by comparing with preset feature amount data of the eyes. Next, the determination unit 16 determines whether or not the number (number) of eyes in the image is equal to or greater than a threshold value (S16). The above-mentioned threshold value for the number of eyes can be set in advance by a user or the like.

  If the number of eyes is not greater than or equal to the threshold (NO in S16), the display control unit 17 displays all of the read display items as they are on the screen (S17). In the process of S16, when the number of eyes is equal to or larger than the threshold (YES in S16), the process of S14 described above is performed.

  Next, it is determined whether or not to end the process (S18). If the process is not terminated (NO in S18), the process returns to S12. When the process is terminated by a user operation or the like (YES in S18), the display control process (application) in the second embodiment is terminated.

  In the second embodiment described above, the control for hiding the secret information may be performed only by the movement amount of the terminal 10 without performing the determination based on the number of eyes or the like. In the second embodiment described above, the display control unit 17 hides the confidential information, and then performs a predetermined operation such as moving the terminal 10 by a predetermined movement amount or touching the screen. Alternatively, the confidential information may be displayed again after a predetermined time has elapsed.

  Further, in the second embodiment, in combination with the first embodiment described above, the inclination and movement amount of the terminal 10 are acquired, and the confidentiality is based on the determination result of either or both of the acquired inclination and movement amount. It may be determined whether or not to hide information.

  Here, FIG. 8 is a diagram for explaining the contents of the second embodiment. FIG. 8A shows an example of definition information in the second embodiment. In the second embodiment, a level to be displayed is set for each display item (item name) of the confidential management data shown in FIG. 3A and for each identification information (user ID) of the user who uses the terminal 10. Thus, the display control unit 17 can perform different display control depending on the level.

  In the example of FIG. 8A, the user set to level 3 can perform non-display control of the item corresponding to level 3, but is not limited to this. For example, by specifying a level range such as levels 1 to 3, non-display control can be performed on items corresponding to levels within the range. The definition of these items and levels may be set by the user in advance or may be acquired from the server via the communication unit 11. Such definition information is stored in the storage unit 14.

  In the example of FIG. 8B, the display control unit 17 acquires the level for the user who has logged into the terminal 10 with the ID of the user 1 (level 3).
