  Note that each direction (position A to position C) representing the above-described three-dimensional object 300 does not necessarily match the position of the viewer viewing the display unit 50 of the display device 100 shown in FIG. Each direction representing the object 300 is a direction within the range of the range in which the three-dimensional object 300 that can be predicted by a viewer who has viewed the display unit 50 from a certain position, that is, a direction in which the three-dimensional object 300 can be expressed without great discomfort It is only necessary that they are almost the same with a certain width.

  The display control unit 40 reads the screen data 400 stored in the screen data storage unit 20 into the display screen data memory 30 when displaying it on the display unit 50. That is, the central screen data 420 displayed in the area 512 is stored in the central screen memory of the display screen data memory 30, and the left screen data 410 displayed in the area 513 is stored in the left screen memory of the display screen data memory 30. The right screen data 430 displayed on the screen is read into the right screen memory of the display screen data memory 30.

  Next, a specific example of the time table stored in the time table storage unit 10 is shown in FIG. Referring to FIG. 5, the time table indicates a time-series order of screens to be displayed. Specifically, a display time and an ID unique to screen data indicating screen data displayed at the display time are displayed. Are associated in time series. The timer control unit 70 refers to the time table stored in the time table storage unit 10 and outputs an instruction signal indicating the screen data to be displayed to the display control unit 40 for each corresponding time.

  When the display control unit 40 receives the instruction signal from the timer control unit 70, the display control unit 40 performs processing for reading the corresponding screen data from the screen data storage unit 20 to the display screen data memory 30.

  Next, the human sensor 60 shown in FIG. 1 will be described. The human sensor 60 is configured by a general sensor using heat, ultrasonic waves, infrared rays, or the like, and detects the presence of a person within a predetermined range. The configuration is not limited in the present invention.

  FIG. 6 is a diagram illustrating a specific example of the sensing range of the human sensor 60. As shown in FIG. 6, the human sensor 60 senses the presence of a person in a range 610 substantially in front of the display unit 50, a range 620 on both sides thereof, and a region 630. When the human sensor 60 senses the range 610, the presence of a viewer located at the position A shown in FIG. In addition, when the human sensor 60 senses the range 620, the presence of the viewer located at the position B shown in FIG. Further, when the human sensor 60 senses the range 630, the presence of a viewer located at the position C shown in FIG. Then, the human sensor 60 outputs a detection signal to the CPU 1.

  The CPU 1 outputs a control signal to the display control unit 40 and the backlight control unit 80 based on the detection signal received from the human sensor 60. Specifically, when the human sensor 60 detects that a person is present only in any one of the sensing ranges 610, 620, and 630, a screen in the direction corresponding to the range (right screen or left) Screen data or a central screen) is displayed on the entire data display unit 51, and a control signal is output to the display control unit 40 so that the opening 522 is configured on the entire slit plate 52.

  When the display control unit 40 executes such control of the display unit 50, the display unit 50 is configured as shown in FIG. FIG. 7 is a diagram specifically showing the configuration of the display unit 50 when the presence of a person is detected only in the sensing range 630 and when it is detected that no person is present in the sensing ranges 610 and 620. In this case, an area 511 for displaying the right screen data is configured on the entire data display unit 51, and the sensing area 630, that is, a viewer located at the position C shown in FIG. 2 is displayed on the entire data display unit 51. The screen data 430 of the right screen to be visually recognized is displayed. An opening 522 is formed in the entire slit plate 52. Therefore, the viewer located in the sensing range 630, that is, the position C shown in FIG. 2 can visually recognize the right screen displayed on the entire screen of the display unit 50 at the position.

  As described above, when the data display unit 51 is divided into the regions 511 to 513 and the right screen data, the central screen data, and the left screen data are displayed in the respective regions, each screen is approximately the same as the data display unit 51. Since the screen is displayed in the range of 1/3 and the viewer views the screen with the size of the data display unit 51, each screen is substantially displayed with about 1/3 of the pixels. Therefore, the viewer browses the screen with pixels coarser than the actual screen data. Therefore, the display device 100 according to the present embodiment displays the screen data corresponding to the entire data display unit 51 when there is no viewer who browses from other directions, thereby browsing the screen with high image quality. Can be made available to viewers.

  As described above, when the data display unit 51 is divided into the regions 511 to 513 and the right screen data, the central screen data, and the left screen data are displayed in each region, each screen is substantially reduced to about Since one-third pixels are displayed, the brightness of each screen is also about １ ／. Therefore, the backlight control unit 80 divides the data display unit 51 into the regions 511 to 513, and the right screen data, the central screen data, and the left screen data are displayed in the respective regions. The aperture ratio of the slit plate 52 is controlled so that the luminance is about three times that in the case where one screen data is displayed on the entire data display unit 51.

  Next, display processing in the display device 100 according to the first embodiment will be described using the flowchart of FIG. The process shown in the flowchart of FIG. 8 is realized by the CPU 1 of the display unit 100 reading out a program stored in the ROM of the storage unit 3 and executing it on the RAM, and controlling each unit shown in FIG.

  Referring to FIG. 8, first, in step S <b> 101, corresponding screen data is read from screen data storage unit 20 in display control unit 40 in accordance with an instruction signal from timer control unit 70.

  The right screen data, left screen data, and central screen data included in the screen data read in step S101 are the right screen memory, left screen memory, and central screen of the display screen data memory 30, respectively, in step S103. In step S105, the data is divided equally in the horizontal direction and displayed in the area 511, the area 513, and the area 513 of the data display unit 51. Further, at that time, in the display control unit 40, the closing portion 521 and the opening portion 522 are configured in the slit plate 52 so that the three screens can be viewed from the respective directions shown in FIG. At the same time, the timer controller 70 starts measuring the display time of the screen.

  When the above three screens are displayed on the display unit 50, when it is detected by the human sensor 60 that the viewer exists only in one of the sensing ranges 610, 620, and 630 (YES in S107) In step S109, the screen data of the screen (right screen, left screen, or center screen) corresponding to the direction of the viewer is displayed on the entire data display unit 51 of the display unit 50, and the entire slit plate 52 is displayed. An opening 522 is formed.

  On the other hand, when it is detected by the human sensor 60 that the viewer is present in at least two of the sensing ranges 610, 620, and 630 (NO in S107), the process in step S109 described above is skipped, The display of the three screens is continued on the display unit 50.

  When the timer control unit 70 counts the predetermined time indicated in the time table after the display of the screen is started in step S105 (YES in S111), the display control unit 40 performs timer control in step S113. In response to the instruction signal from unit 70, the next screen data shown in the time table is read from screen data storage unit 20.

  When the next screen data is read from screen data storage unit 20 in step S113, the process is returned to step S103, and the above-described display process is repeated.

  The above is the display processing in the display device 100 according to the first embodiment.

  By executing the above-described display processing in the display device 100 according to the present embodiment, it is possible to view another screen from three directions of the three-dimensional object at the same time using one display device. . In this way, each viewer can view the three-dimensional object accurately as if he / she was observing the three-dimensional object by viewing the display device from each direction. Can grasp.

  Further, the display can be made more appealing by switching and displaying the screen data at regular intervals according to the time table.

  In addition, when there are only viewers from one direction, the screen corresponding to the direction is displayed on the entire screen, so that the viewer in that direction can see a three-dimensional object on a screen with higher image quality.

[Modification 1]
In the above-described embodiment, as described with reference to FIG. 2, the central screen displayed in the direction toward the position A on the display unit 50, and the left screen displayed in the direction toward the position B; Although three screens with the right screen displayed in the direction toward the position C are displayed, as a modification, as shown in FIG. 11, a screen that can be viewed from all directions together with the three screens (common) May be displayed). For example, a screen representing an image of the three-dimensional object 300 may be displayed as the three screens, and a screen displaying an explanatory text explaining the three-dimensional object 300 may be displayed as the common screen.

  Furthermore, in the first modified example, together with the above three screen data, screen data (for example, explanatory text) displayed on the common screen is stored and displayed in the screen data storage unit 20 as a set of screen data. It is preferable that the screen data displayed on the common screen also changes according to the above three screen data.
