Abstract

There is provided a control device including an illumination control unit that controls an illumination device illuminating a non-display region of a light-shielding unit that includes a display region in which an image is displayed and the non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user. The illumination control unit controls the illumination device according to display content of the display region.

Claims

1. A control device comprising:

an illumination control unit that controls an illumination device illuminating a non-display region of a light-shielding unit that includes a display region in which an image is displayed and the non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user,

wherein the illumination control unit controls the illumination device according to display content of the display region.

2. The control device according to claim 1, wherein the illumination control unit controls the illumination in conjunction with information on the image displayed in the display region.

3. The control device according to claim 2, wherein the illumination control unit controls the illumination device based on information on pixels constituting a predetermined region of the image displayed in the display region.

4. The control device according to claim 3, wherein the illumination control unit controls the illumination based on information on pixels located near a periphery of the display region among the pixels constituting the image displayed in the display region.

5. The control device according to claim 2, wherein the illumination control unit controls luminance of the illumination in conjunction with luminance of the image displayed in the display region.

6. The control device according to claim 2, wherein the illumination control unit controls a color of the illumination in conjunction with a color of the image displayed in the display region.

7. The control device according to claim 1, further comprising:

an image control unit that displays an image displayed in a region close to the non-display region in the display region in a manner that the image is gradually blurred.

8. The control device according to claim 7, wherein the image control unit controls luminance of the image displayed in the display region according to luminance of the non-display region.

9. The control device according to claim 2, wherein the illumination control unit controls illumination to a part of the non-display region based on information on an image displayed in a part of the display region adjacent to the part of the non-display region which is an illumination control target.

10. The control device according to claim 1, further comprising:

an environmental light detection unit that detects environmental light of an external environment exposed from a surface of the light-shielding unit located opposite a surface including the display region and the non-display region,

wherein the illumination control unit controls the illumination according to the environmental light.

11. The control device according to claim 10, wherein the illumination control unit controls the luminance of the illumination in conjunction with an intensity of the environmental light.

12. The control device according to claim 10, wherein the illumination control unit controls a color of the illumination in conjunction with a color of the environmental light.

13. The control device according to claim 1, wherein the illumination control unit changes the illumination to the non-display region based on meta information on the image displayed in the display region.

14. The control device according to claim 1, wherein the illumination control unit changes the illumination according to a predetermined rhythm.

15. A display device comprising:

a light-shielding unit that includes a display region in which an image is displayed and a non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user;

an image display unit that displays the image in the display region;

an illumination unit that illuminates the non-display region; and

an illumination control unit that controls the illumination to the non-display region located in a periphery of the display region.

16. The display device according to claim 15, wherein the illumination unit is disposed in a periphery of the image display unit.

17. A control method comprising:

controlling an illumination device that, according to display content of a display region, illuminates a non-display region of a light-shielding unit that includes the display region in which an image is displayed and the non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user.

18. A program for causing a computer to realize:

an illumination control function of controlling an illumination device illuminating a non-display region of a light-shielding unit that includes a display region in which an image is displayed and the non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user,

wherein the illumination control function controls the illumination device according to display content of the display region.

19. An illumination control method comprising:

controlling illumination to a non-display region located in a periphery of a display region according to information on an image displayed in the display region when the non-display region is illuminated by displaying the image in the display region in a light-shielding unit that includes the display region in which the image is displayed and the non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user.

20. A program for causing a computer to realize:

an image display function of displaying an image in a display region in a light-shielding unit that includes the display region in which the image is displayed and a non-display region in which the image is not displayed and is designed to be disposed in a region covering a visual field of a user; and

an illumination control function of controlling the illumination to the non-display region located in a periphery of the display region by controlling an illumination unit illuminating the non-display region.
