ABSTRACT:
To provide an image display system, projector, image processing method, program and information storage medium enabling to shorten the time required for calibration when the color and brightness of an image is corrected in consideration of the influence of the ambient light, there is provided a liquid crystal projector having: a calibration signal generation section for generating four types of calibration image signals; a color light sensor for colorimetry of calibration images; a color correction section for correcting image information based on the color information from the color light sensor to correct the color of the image; and a brightness correction section for correcting the image information based on the color information from the color light sensor to correct the brightness of the image. The liquid crystal projector displays the image after the image information is corrected such that the color and brightness of the image are corrected according to the viewing environment.
