Problems solved by technology

[0003] The de-interlacing processing method in the prior art, because there is no special processing for the edge of the image, the judgment of the direction of the edge of the image is not accurate, and the effect of the converted image is not good, especially in the processing of low-angle edges, there are often Visible aliasing

Abstract

The invention provides a deinterlacing processing method including: scanning original pixels of an original image by the aid of a first scanning window, and during scanning, judging the range of the angle of a to-be-interpolated pixel point according to the first scanning window; if the range of the angle of the to-be-interpolated pixel point is a low-angle range, acquiring gradient information of original pixel points in an upper line and a lower line which are adjacent to the to-be-interpolated pixel point, and determining the direction of the to-be-interpolated pixel point according to the gradient information of the original pixel points in the upper line and the lower line which are adjacent to the to-be-interpolated pixel point; and interpolating the to-be-interpolated pixel point according to the direction of the to-be-interpolated pixel point. By the deinterlacing processing method in the embodiment, accuracy for determining the direction of the to-be-interpolated pixel point during deinterlacing processing is greatly improved.

Description

technical field [0001] The invention relates to video processing technology, in particular to a deinterlacing processing method. Background technique [0002] Display devices in the prior art, such as liquid crystal display panels and plasma display panels, etc., all use progressive scanning, while video sources, such as DVD, Blu-ray DVD, etc., always record and save video content in an interlaced manner. Interlaced video is stored and displayed in alternate odd and even fields. The number of effective lines is half that of progressive video. The main format is 480i, 576i or 1080i, etc., which can save storage space and transmission bandwidth. However, when displaying video content through a display device, video de-interlacing processing is often required to convert it into a progressive format. Video de-interlacing means inserting a new line between each line of an interlaced image to fill in a complete progressive scan image processing process. [0003] The de-interlaci...
