ABSTRACT:
In order to provide an image display system, a projector, a program, an information storage medium, and an image processing method that make it possible to perform calibration without interrupting the display of an image for a presentation or the like, an image processing section of a projector is provided with an area identification section that identifies a display area and a non-display area, based on environmental information measured by a CCD sensor; a brightness change derivation section that derives any change in the brightness of the non-display area; a grayscale correction parameter derivation section that derives a grayscale correction parameter corresponding to the change in brightness; and a 1D-LUT generation section that generates a 1D-LUT used in the correction of brightness in accordance with the grayscale correction parameter.
