Abstract:
1. A display device which displays an image, comprising: a light source which emits light; a light deflector having a deflection region in which the light from the light source is deflected toward a predetermined position; a display panel on which the image is formed by the light from the light deflector; a camera which captures an image of a front area of the display device; and a controller that determines, based on the image captured by the camera, a total number of right and left eyes of one or more users viewing the image displayed on the display panel, and controls operation of the light deflector based on the determined total number of right and left eyes so that the light deflected by the light deflector is directed alternately toward a right eye and a left eye of each of the one or more users, wherein the controller segments the deflection region into deflection subregions based on the determined total number of right and left eyes, and controls light deflection in the deflection subregions so that the light from the light source is deflected toward different positions at a same time, the controller sets a total number M of the deflection subregions that satisfies a relational expression (N×ΔT)/M≦Frame_T, where ΔT is a unit deflection time to be taken for the light deflector to deflect light from the light source toward any eye of the one or more users, Frame_T is a display time during which a frame of the image is displayed on the display panel, and N is the determined total number of right and left eyes, and the controller controls the light deflection in the deflection subregions so that the light is deflected toward the right and left eyes of the one or more users within the display time Frame_T.
