Abstract

The invention discloses a video de-interlacing method and a video de-interlacing device. The method is characterized in that original video frames are restored by adaptively selecting a proper method according to characteristic analysis among frames in video frames, thereby greatly reducing the flicker effect between lines and the parallel phenomenon.

Description

technical field [0001] The present invention relates to the field of video encoding and decoding, in particular to a video deinterlacing method and device. Background technique [0002] There are two video signal scanning methods: progressive scanning and interlaced scanning. The interlaced scanning method is to divide a frame of image into odd field and even field, process them separately, and finally combine the odd and even fields to restore the original image. The interlaced scanning method can reduce the bandwidth, but there are some shortcomings such as crawling, edge feathering or interlacing, so it is necessary to eliminate the above-mentioned shortcomings through the deinterlacing algorithm. According to different interpolation methods, these algorithms can be divided into two categories: intra-field interpolation and inter-field interpolation. Intra-field interpolation includes line repetition and linear filtering, while inter-field interpolation is mainly based o...
