发明名称 Image processing apparatus
摘要 An image processing apparatus is provided that performs more appropriate black stretch processing to display a high quality video. The image processing apparatus includes a luminance characteristics detection unit that analyzes a received video signal to detect a frequency of each of a plurality of luminance areas with a luminance at least equal to or lower than a predetermined luminance, a black stretch processing unit that performs black stretch processing for a luminance signal with a luminance equal to or lower than a predetermined luminance level, and a microcomputer that uses the frequency of each of the plurality of luminance areas, detected by the detection unit, to control the black stretch processing of the black stretch processing unit.
