摘要

To provide an image processing system and the like which can perform an image distortion correction and focus adjustment approximately at the same time without changing a projecting position intended by a user, a projector includes: a distortion correcting section 120 which corrects image signals to adjust the distortion in an image; an image projection section 190 which includes a lens unit 198 having a focus adjustment function, the lens unit 198 projecting an image based on the corrected image signals; a control section 160 and a focus lens driving section 162 which control the driving of the lens unit 198 so that the focal length of the lens unit 198 to an image projection area changes; a sensing section 180 which senses the projected image; and a distortion correction deriving section 140 which derives the focal length to the center of the image projection area and also an amount of distortion correction provided by the distortion correcting section 120, based on sensing information.
