Video processing device and display device

A display device, comprising:

• a video acquisition part, acquiring a video comprising a plurality of segmented regions, each of which comprises a plurality of pixels;
• a video processing part, performing video processing on the video and generating a display video;
• and
• a display part, displaying the display video, and
• wherein the video processing part comprises:
• a local histogram generation part, generating a histogram showing a brightness distribution per pixel for each of the segmented regions of the video;
• a local tone curve generation part, generating a tone curve for adjusting a brightness of the video for each of the segmented regions based on the histogram for each of the segmented regions;
• a luminance boundary region detection part, comparing tone curves between adjacent segmented regions among the segmented regions, specifying a boundary between adjacent segmented regions for which a comparison result of the tone curves becomes a predetermined condition as a luminance boundary, and specifying a region within a predetermined range including the luminance boundary as a luminance boundary region;
• and
• a video correction part, performing correction processing to correct a luminance of the video based on the tone curve and a specified result of the luminance boundary region.
