Abstract
A reflectance/transmittance of an optical device disposed at a position through which image light emitted from a liquid crystal display displaying an icon passes is changed according to an anti-glare level to achieve anti-glare of the reflected image. A color of the icon displayed on the liquid crystal display is adjusted such that the higher the transmittance of the optical device is, the lower the lightness is, so that the icon of a similar color is visually recognized regardless of the reflectance/transmittance of the optical device.
Claims7
A display system for displaying video of a display object with a reflected image in a superimposed manner, the display system comprising:
- a display device including a display and an optical device configured to control reflectance/transmittance of incident light;
- and
- a display control unit configured to display a display object on the display and an optical device control unit configured to change reflectance/transmittance of the optical device, wherein
- the display emits image light of the display object,
- the optical device is disposed on a first direction side of the display so as to overlap a screen of the display when viewed in the first direction, the first direction being an emission direction of image light of the display, and
- the display control unit changes, according to the reflectance/transmittance of the optical device, a display color of the display object on the display so as to reduce a change in color of the display object visually recognized by a user with a change in the reflectance/transmittance of the optical device.
