Bildverarbeitungssystem, Projektor und Bildverarbeitungsmethode

摘要

To provide an image processing system and the like which can correct a distortion in a projected image automatically and adequately, a projector has an area sensor section 182 which senses a sensing region onto which an image is projected and outputs sensing information; a storage section which stores angle correction data 124 in which the ratio of average luminance values for a plurality of different regions in the projection area is associated with derivation coordinates for deriving coordinates of the projection area, and also stores coordinate data 122 indicating the derivation coordinates for the projection area; luminance-distribution analyzing section 160 which refers to the angle correction data 124 based on the sensing information and depending on the luminance distribution in the projection area and corrects the derivation coordinates in the coordinate data 122, based on the angle correction data 124; and a distortion correction section 130 which corrects the image signals so that the distortion in the projected image is corrected, based on the coordinate data 122.
