Abstract

An image displaying apparatus and method is provided which can provide a satisfactory display with a gradation of intensity even with a spatial light modulator which provides a binary light modulation. A light from a light source 1 is modulated by a spatial light modulator 3 which modulates a light at each pixel thereof correspondingly to a pixel data of an image to be displayed. When the pixel state of the spatial light modulator 3 is being changed, the light source 1 is turned off. When the pixel state of the spatial light modulator 3 is steady, a light pulse is irradiated from the light source 1 to the spatial light modulator 3 to display the image.
