Abstract:
According to one embodiment, a video display apparatus having a smoothing processing unit inputs luminance signals of pixels which form an image, acquires histogram data by counting the numbers of pixels for respective levels of the input luminance signals, sets a correction amount for a change amount of the levels of luminance signals based on the acquired histogram data, corrects the change amount of the levels of luminance signals near a pixel to be processed based on the correction amount, and corrects the level of the input luminance signal for the pixel to be processed using the corrected change amount of the levels of luminance signals.
