Patent ID: 8083358

Claim:
A projector, comprising: an illumination device that radiates plural colors of light in a time-sharing manner; a reflective optical modulator that forms, based on input image information, an optical image for each of the plural colors of light radiated from the illumination device in a time-sharing manner; a projection optical device that projects the optical images of the plural colors of light formed by the reflective optical modulator; and a controller that controls the illumination device and the reflective optical modulator, the controller including: an image information analyzer that analyzes the input image information; and an illumination time controller that dynamically changes and controls illumination time of the plural colors of light by the illumination device based on an analysis result by the image information analyzer, wherein the input image information is provided by a plurality of frames, the image information analyzer acquires one of pixels of the plural colors of light with the highest gradation value in each of the frames, the illumination time controller sets the illumination time based on the one of the pixels of the plural colors of light with the highest gradation value, controls the illumination device so that a blank time of the illumination in one of the frames is eliminated to continuously and repeatedly radiate each of the plural colors of light, and controls the light amount of the illumination device in accordance with illumination times in one of the frames of the plural colors of light.
