Patent ID: 8797347

Claim:
An image processing apparatus that inputs video image data of a plurality of frames and displays a plurality of images comprising a plurality of frames based on the video image data on a display unit, the image processing apparatus comprising: a correction unit that corrects image data for each frame of the plurality of frames with a correction amount corresponding to a value of the image data, and that outputs corrected image data for each frame; a brightness control unit that controls an overall brightness of image data for each frame of the plurality of frames; and a detection unit that detects a scene change between one of the images and the next image in the plurality of images comprising the plurality of frames, wherein the brightness control unit includes: (a) a first brightness control unit that calculates a first gain from the corrected image data of a frame and multiplies the first gain by image data of a following frame prior to input into the correction unit; and (b) a second brightness control unit which, when a scene change is detected by the detection unit, calculates a second gain on the basis of a difference between (i) the first gain which is calculated from the corrected image data of a current frame and (ii) the first gain which has been calculated from the corrected image data of a preceding frame, and multiplies the second gain by the corrected image data of the current frame, and which, when a scene change is not detected by the detection unit, multiplies a gain of 1 by the corrected image data of the current frame or bypasses the multiplication of the second gain.
