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

摘要

An image processing system, a projector, an information storage medium, and an image processing method are provided to correctly detect an end point of a projection area in an image pick-up area based on image pick-up information. An image projection part(190) projects the first and second calibration images at different visual points. An image pick-up part has an exposure control function and picks up the first and second calibration images so as to generate the first and second image pick-up information. A difference information generation part(152) generates difference information that indicates difference of an image signal value corresponding to each pixel in an image pick-up area of the image pick-up part for each calibration image on a basis of the first and second image pick-up information. An end point detection part(154) detects an end point of a projection area in the image pick-up area from the difference information as a search target.
