Abstract:
1. A video processing apparatus comprising: a histogram generator configured to: divide an area of a screen, in which a video is displayed, in to first to fourth areas in a longitudinal direction, and generate luminance histograms corresponding to the first to fourth areas respectively based on levels of pixels of the first to fourth areas; and divide the area in to fifth to eighth areas in a lateral direction, and generate luminance histograms corresponding to the fifth to eighth areas respectively based on levels of pixels of the fifth to eighth areas; and a determination module configured to: compare the luminance histograms corresponding to the first to fourth areas; compare the luminance histograms corresponding to the fifth to eighth areas; determine whether the video represents a stereoscopic video and, if the video represents stereoscopic video, a format of the stereoscopic video based on a first result of a comparison of the luminance histograms corresponding to the first to fourth areas and a second result of a comparison of the luminance histograms corresponding to the fifth to eighth areas.
