Abstract
An image distortion correction circuit performs a distortion correction process on an image signal on the basis of distortion correction data to generate a distortion-corrected image signal. The distortion correction data is for correcting coordinate positions of display data fragments corresponding to respective N coordinate positions in the display image to first to N-th distortion correction coordinate positions. The image distortion correction circuit determines a distortion correction coordinate position where abnormality occurs as an abnormal coordinate position among the first to N-th distortion correction coordinate positions on the basis of respective intervals between the adjacent first to N-th distortion correction coordinate positions indicated by the distortion correction data. The image distortion correction circuit corrects a part corresponding to the abnormal coordinate position in the distortion correction data on the basis of at least the two distortion correction coordinate positions excluding the abnormal coordinate position among the first to N-th distortion correction coordinate positions.
