Patent ID: 8079716

Claim:
An image processing system comprising: a determination unit that determines a distortion state of a projected image; and a correction unit that performs distortion correction of the image according to the distortion state, wherein: a shape of the image in a display area of an optical modulator after distortion correction has four apexes and is distorted from a shape of the image in the display area of the optical modulator before distortion correction in both vertical and horizontal directions, the correction unit performs distortion correction calculation using a center of gravity of the image after distortion correction in the display area of the optical modulator as the origin, the center of gravity being located at equal distances to each of the four apexes of the image after distortion correction in the display area of the optical modulator, and the correction unit performs the distortion correction calculation after moving the image in the display area of the optical modulator after distortion correction so that the origin of the image in the display area of the optical modulator after distortion correction coincides with a center of the display area of the optical modulator.
