Abstract
A light source, an image display panel including multiple pixel regions, each of which modulates light, light control means for focusing light from the light source onto associated pixel regions according to their wavelength ranges, and optical systems that form an image on a projection plane by the light that has been modulated by the panel are provided. A circuit for generating data representing multiple image subframes from data representing each image frame as a component of the image and getting the subframes displayed by the panel time-sequentially, and an image shifter for shifting a selected one of the subframes on the projection plane are further provided. The same area on the projection plane is sequentially irradiated with light rays that have been modulated by different pixel regions of the panel and that fall within respectively different wavelength ranges.
