Abstract
In a head mounted display, an image is displayed with central resolution higher than peripheral resolution or the peripheral resolution is not necessarily high resolution, and a controller changes the display aspect of the image formed by an image formation apparatus in accordance with a change in the sightline detected with a sightline sensor.
Claims14
A head mounted display comprising:
- an image display section that displays a high resolution central image in a central image display area and a low resolution peripheral image in a peripheral image display area that is outside the central image display area on the image display section, the high resolution central image having a resolution higher than a resolution of the low resolution peripheral image, the image display section covering a front side of a viewer's eye;
- a sightline detection section that detects a sightline;
- and
- an image control section that changes a display aspect of an image displayed by the image display section when the sightline detection section detects that a sightline direction of the viewer's eye has changed by an angle greater than a predetermined value, wherein
- the high resolution central image displayed in the central image display area of the image display section is a circular image having an angular range between 5° and 10° with respect to an image center, the image center being a sightline reference axis corresponding to the sightline direction of the viewer's eye.
An image formation optical system that forms a high resolution central image in a central image display area of an image display section and forms a low resolution peripheral image in a peripheral image display area that is outside the central image display area on the image display section,
- the image display section covering a front side of a viewer's eye,
- the high resolution central image having a resolution higher than a resolution of the low resolution peripheral image, according to a change in eyesight in relation to a visual field of the viewer's eye, wherein:
- the high resolution central image displayed in the central image display area of the image display section is a circular image having an angular range between 5° and 10° with respect to an image center, the image center being a sightline reference axis corresponding to a sightline direction of the viewer's eye;
- and
- the resolution of the low resolution peripheral image is set to be higher than resolution converted from the eyesight corresponding to an assumed visual field of the viewer's eye.
