Embodiment Construction

[0039] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] First, the method of the present invention is described in a simple case, that is, only the video sequence with a unique pattern is judged and processed. In the first step, the input video sequence is judged and classified into one of the following types: film-mode video sequence or non-film-mode video sequence. The specific method can refer to the patent application No. 200810110925.6 submitted by the applicant to the China Patent Office. It should be noted that the video source in this application is an interlaced video source, and the video source in this embodiment is a progressive video source. The principles of the video type judgment methods of the two are the same, and the video type judgment method of the progressive video source can be deduced from the video type judgment method of the interlaced video source.

Abstract

In order to solve the problems that the prior transformation method on video frame rate cannot solve moving object sheltering and irregular motion well, the invention provides a video frame rate upconversion method, which comprises the following steps: ranking a video sequence to be processed as a film mode video sequence or a non-film mode video sequence; carrying out frame selection of the film mode video sequence; carrying out motion estimation and motion compensation processing of the film mode video sequence processed in the previous step; and carrying out processing such as low-frequency frame insertion or repeated frame insertion for the non-film mode video sequence. The video frame rate upconversion method can be used for frame rate conversion of a video sequence.

Description

technical field [0001] The invention relates to video sequence processing technology, especially the technology of inserting images in video sequence. Background technique [0002] At present, in order to achieve a clearer display effect, TV sets often need to be able to play video sequences at a higher frame rate. Therefore, to increase the frame rate of the input video sequence, the frame rate up conversion technology (FRUC) can be used to The frame rate of the video sequence in the input video signal is improved, and the frame rate up-conversion technology mainly includes: inserting repeated frames, inserting black (gray) frames, motion estimation motion compensation (MEMC), and inserting low-frequency frames. [0003] Existing video signals can be divided into two categories according to the characteristics of the video sequences they contain: film-mode video sequences and non-film-mode video sequences. There are repeated frame images in the film mode video sequence, su...
