ABSTRACT:
In order to provide a projection system, projector, program, information storage medium and image processing method which can reduce an unpleasantness to an observer in an image calibration when it is executed in consideration of the ambient light, a calibration information output section selects and outputs calibration information, a color light sensor then measures XYZ values in the respective projected calibration images, and a measurement data is then stored in a sensing value holding section, when a synchronizing signal judgment section judges that no synchronizing signal has been inputted. When all the color correcting measurement data have been provided, a 3D-LUT update section updates a 3D-LUT stored in the 3D-LUT storage section, based on the measurement data. When all the brightness correction measurement data have been provided, a 1D-LUT update section updates a 1D-LUT stored in a 1D-LUT storage section to execute the calibration, based on the measurement data.
