摘要：
An image processing system includes 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 the correction unit performs distortion correction calculation using either an intersection point of diagonal lines of the image after distortion correction in a display area of an optical modulator or a center of gravity of the image as the origin.
