Problems solved by technology

However, the patent must read the video signal according to the first update frequency and output the adjusted video signal according to the second update frequency
That is to say, this patent must implement timing control (timing control) operations, so it is necessary to increase the setting of circuits related to timing control, and increase additional cost expenditures
In addition, for liquid crystal display devices (LCD), time control sometimes causes panel compatibility issues, or even some panels do not allow changing the display timing

[0039] Please refer to" Figure 5 ", this figure shows the flow chart of the first embodiment of the video processing method, including the following steps.

[0040] Step S510: Receive an input video signal, and a single period of the input video signal has a plurality of first input frames and a plurality of second input frames.

[0041] Step S520: Processing the input video signal to generate an output video signal, the output video signal has a plurality of first output frames and a plurality of second output frames in a single period, and the number of the first output frames and the second output frames are the same .

[0042] Wherein, the sum of the numbers of the first output picture and the second output picture is an integer multiple of the sum of the numbers of the first input picture and the second input picture.

[0043] The quantity ratio of the above-mentioned first input frame to the second input frame is the first ratio, and the quantity ratio of the first ou...

Abstract

The invention relates to a method and a device for processing a video. The method comprises the following steps of: receiving an input video signal which comprises a plurality of first input pictures and a plurality of second input pictures in a single circle; and processing the input video signal to generate an output video signal which comprises a plurality of first output pictures and a plurality of second output pictures in the single circle, wherein sum of the first output pictures and the second output pictures is integral multiple of the sum of the first input pictures and the second input pictures.

Description

technical field [0001] The present invention relates to a video processing method and device, in particular to a video processing method and device in which video objects do not move smoothly. Background technique [0002] Video images have a variety of different frequencies, for example: 24Hz for movies (that is, shooting / playing at a rate of 24 frames per second); 60Hz for the National Television Standard Committee (NTSC) specification; The specification of the alignment (Phase Alternating Line, PAL) is 50 Hz or the like. Therefore, when various playback devices, such as televisions or digital video disc (DVD) players, play image data of different frequencies, the image data must be converted into a compatible playback specification through video processing. [0003] MEMC (motion-estimation-motion-compensation) is one of the typical video processing methods. In order to interpolate image data of a certain frequency to generate image data of another frequency for display,...
