Abstract

A head-mount type display device adapted to allow a user to visually recognize a virtual image in a state of being worn on the head of the user includes an image display section having an image light generation section adapted to generate an image light representing an image, a light blocking section adapted to transmit external light at a predetermined transmittance, and a virtual image forming section adapted to transmit the external light transmitted through the light blocking section and to form the virtual image in an eye of the user with the image light, and configured to allow the user to visually recognize the virtual image and an external image, an operation section with which the user inputs operation data, and a control section adapted to perform control of changing the transmittance of the light blocking section in accordance with operation data from the operation section.

First claim

What is claimed is:

1. A head-mount type display device adapted to allow a user to visually recognize a virtual image in a state of being worn on the head of the user, comprising:
an image display section having an image light generation section adapted to generate an image light representing an image, a light blocking section adapted to transmit external light at a predetermined transmittance, and a virtual image forming section adapted to transmit the external light transmitted through the light blocking section and to form the virtual image in an eye of the user with the image light, and configured to allow the user to visually recognize the virtual image and an external image;
an operation section with which the user inputs operation data; and
a control section adapted to perform control of changing the transmittance of the light blocking section.

2. The head-mount type display device according to claim 1 , wherein
the control section controls the transmittance of the light blocking section based on an operation of the operation section.

3. The head-mount type display device according to claim 1 , wherein
the control section controls the transmittance of a first region of the light blocking section and the transmittance of a region other than the first region independently from each other.

4. The head-mount type display device according to claim 3 , wherein
the control section performs control of changing at least one of a size and a position of the first region.

5. The head-mount type display device according to claim 3 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with one of a size of subtitles and a position of the subtitles.

6. The head-mount type display device according to claim 3 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with one of a type of a moving image and a type of an application.

7. The head-mount type display device according to claim 3 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with a positional relationship regarding whether or not a video screen recognized as the external image and subtitles overlap each other.

8. The head-mount type display device according to claim 3 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region so as to make the external image eye-friendly in a case of watching a fast-moving movie.

9. A head-mount type display device adapted to allow a user to visually recognize a virtual image in a state of being worn on the head of the user, comprising:
an image display section having an image light generation section adapted to generate an image light representing an image, a light blocking section adapted to transmit external light at a predetermined transmittance, and a virtual image forming section adapted to transmit the external light transmitted through the light blocking section and to form the virtual image in an eye of the user with the image light, and configured to allow the user to visually recognize the virtual image and an external image;
a detection section provided to the image display section, and adapted to detect a movement of the head of the user; and
a control section adapted to perform control of changing the transmittance of the light blocking section in accordance with detection data detected by the detection section.

10. The head-mount type display device according to claim 9 , wherein
the control section controls the transmittance of a first region of the light blocking section and the transmittance of a region other than the first region independently from each other.

11. The head-mount type display device according to claim 10 , wherein
the control section performs control of changing at least one of a size and a position of the first region.

12. The head-mount type display device according to claim 10 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with one of a size of subtitles and a position of the subtitles.

13. The head-mount type display device according to claim 10 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with one of a type of a moving image and a type of an application.

14. The head-mount type display device according to claim 10 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region independently from each other in accordance with a positional relationship regarding whether or not a video screen recognized as the external image and subtitles overlap each other.

15. The head-mount type display device according to claim 10 , wherein
the control section controls the transmittance of the first region of the light blocking section and the transmittance of the region other than the first region so as to make the external image eye-friendly in a case of watching a fast-moving movie.
