IMAGE PROCESSING SYSTEM, PROJECTOR, INFORMATION STORAGE MEDIUM, AND IMAGE PROCESSING METHOD

摘要

An image processing system including: a distortion correction section 130 which corrects an image signal so as to adjust image distortion; an image projection section 190 which projects an image based on the image signal; a sensing section 180 which senses the projected image along an optical axis which does not coincide with an optical axis of the image projection section in order to generate sensing information; an image analysis section 150 which generates edge point information and brightness index value distribution information, based on the sensing information, the edge point information showing a position of a predetermined edge point of the projected image in the sensed image, and brightness index value distribution information showing a distribution of brightness index values of the projected image; and a correction information generation section 120 which generates projection distance information which shows a projection distance, based on the edge point information, and generates correction information for correcting the image signal, based on the projection distance information and the brightness index value distribution information;
