DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JP2023147782
Kind Code:
A
Abstract:
To provide a display system which can improve the visibility between a plurality of display devices.SOLUTION: A display system according to an embodiment comprises: a first display device which emits first display light related to a first image that is visually recognized by a viewer by being superimposed on an actual scene; a second display device which emits second display light related to a second image that is visually recognized by the viewer without being superimposed on the actual scene; an illuminance acquisition unit which acquires illuminance of external light; and a display control unit which controls the first display device and the second display device so as to reduce luminance of the first display light and the second display light as the illuminance decreases. The display control unit executes first luminance control of controlling the first display device and the second display device such that an inter-display unit luminance difference being a difference between the luminance of the first display light and the luminance of the second display light changes at a first change rate when the illuminance is higher than prescribed illuminance, and executes second luminance control of controlling the first display device and the second display device such that the inter-display unit luminance difference changes at a second change rate smaller than the first change rate when the illuminance is equal to or less than the prescribed illuminance.SELECTED DRAWING: Figure 5
