Provided are a display device and a video signal processing method. The device is used for receiving a video signal which is provided with multiple frames, and each frame is provided with an odd field and an even field. The device comprises a processor and a display module. The processor comprises the execution steps that whether the odd field or the even field of each current frame and the odd field or the even field of the corresponding previous frame in the multiple frames are similar or not is judged respectively; one of multiple patterns corresponding to the current frame is generated according to the judgment result, wherein the patterns at least comprise the first pattern, the second pattern, the third pattern and the fourth pattern; the numbers corresponding to the first pattern, the second pattern, the third pattern and the fourth pattern are added up respectively in the first period; whether the video signal is the video signal converted from a filmstrip or not is judged according to the numbers of the first pattern and the second pattern or the number of the fourth pattern; when the video signal is converted from the filmstrip, processing is conducted on the previous frame, the current frame and the next frame to generate an output frame according to the pattern corresponding to each current frame. The display module displays the output frame in a mode of scanning line by line.
Description
technical field [0001] The present invention relates to a display device and a video signal processing method, in particular to a display device and a video signal processing method for judging the source of a video signal by accumulating the number of patterns generated in two adjacent frames. Background technique [0002] Modern common display devices, such as liquid crystal displays, plasma displays, digital projectors, etc., can receive video signals in two different formats, namely video converted from film and ordinary video taken by general digital cameras. (normal video), where the video converted from the movie film is in the unit of frame (frame), and the normal video is in the unit of field (field) and two adjacent fields form a frame, and the playback rate of the two is also different. In order to play the frame with film as the initial recording medium on the aforementioned modern common display device, the film frame (filmframe) must be converted into video fra...
