Abstract
An image processing unit performs gamma correction on a video signal using a gamma characteristic selected from among a plurality of gamma characteristics. Further, in a case where a gamma characteristic used in the gamma correction is changed by selection of the gamma characteristic, the image processing unit calculates a contour correction characteristic corresponding to the changed gamma characteristic and performs contour correction using the contour correction characteristic on the video signal.
