ABSTRACT:
To provide a projection type image display system, projector, program, information storage medium and image projection method which can project an image applicable to viewing environment of a changed projection position, a liquid crystal projector is provided with: a sensor for sensing a projection target area and outputting sensing information; an edge detection section for outputting detection information based on the sensing information; a projectable area determination section for determining a projectable area based on the detection information; a projection area selecting section for selecting a projection area from the projectable area; a sensing data generation section for generating sensing data applicable to viewing environment of the selected projection area, based on the sensing information of the selected projection area; an LUT data generation section for generating LUT data; a correction section for correcting image information based on the generated LUT data; and an image projection section for projecting an image onto the projection area based on the corrected image information.
