PROBLEM TO BE SOLVED: To extract a feature quantity of an image accurately in order to make an image quality setting optimum for the image.SOLUTION: Video data outputted from a separation/decoding part 15 is outputted to a video processing part 18 and a feature quantity extraction part 19. At the feature quantity extraction part 19, an edge histogram extraction part 191 extracts an edge histogram of the video data, a histogram extraction part 192 extracts a luminance histogram of the video data, and a frame difference histogram extraction part 193 extracts a frame difference histogram of the video data. A telop detection part 201 sets, at the video processing part 18, an image quality setting parameter corresponding to the presence or absence of a telop detected based on the edge histogram and the luminance histogram. A scene change detection part 202 sets, at the video processing part 18, an image quality setting parameter corresponding to the presence or absence of a scene change detected based on the frame difference histogram and the luminance histogram. The video processing part 18 performs video processing in accordance with the image quality setting parameters and causes a display part 21 to perform displaying. |
