Abstract

The invention discloses a motion compensation accessory movement self adaptive de-interlacing method, which aims at the fact that the visual system of human eye is very sensitive to slow motion and has high resolving capability to the slow motion and for the objects in slow motion, the motion compensation deals based on motion estimation are carried on, while for the objects in fast motion, to which human eye is not sensitive, the movement self adaptive interlacing deals which are characterized by easy hardware implementation are carried on. As motion compensation arithmetic only focuses on the treatment of objects in slow motion, the invention can greatly reduce the complexity of the arithmetic and the corresponding hardware design cost. At the same time, on the base of analyzing interlacing video sampling characteristics, the invention optimizes the compensation arithmetic of classic motion, which puts forward that in different polarity fields, horizontal and vertical motion vectors should be found and the sub-pixel compensation method should be used for improving the definition of images in vertical direction aiming at the deadly defect that in the process of interlacing sampling, the definition of image in vertical direction is seriously influenced.

Description

technical field

[0001] The invention relates to a de-interlacing method in computing video and digital television post-processing, in particular to a video de-interlacing method utilizing motion compensation of human visual characteristics to assist motion self-adaptation. Background technique

[0002] With the emergence of high-definition large-screen display devices with progressive scan format such as high-definition TV, LCD TV LCD, PC video, rear-projection TV, and plasma TV (PDP), the traditional interlaced scanning technology is inherently The phenomenon of damaging image quality cannot be eliminated due to the characteristic, which can no longer meet people's current needs. Therefore, in the transition stage where interlaced and progressive scanning technologies coexist, there is a wide demand for format conversion of video signals between different transmission and display devices.

[0003] De-interlacing processing technology is an indispensable part of the video s...
