Problems solved by technology

[0008]The traditional median filter deinterlacing method has good characteristics on the vertical border, and it has a small hardware implementation cost, but for the oblique edge Images can result in blurred and visually unrealistic images
[0009] can also make some improvements to the traditional median filter de-interlacing method, such as combining motion compensation, etc., the US Patent No. 6414719 proposes an improved The median filtering deinterlacing scheme, but it is also more complicated, which is not conducive to the realization of hardware

Embodiment Construction

[0028] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0030] The first embodiment of the present invention relates to a de-interlacing pixel point interpolation method, the process of which is as follows figure 1 shown.

[0031] In step 101, three adjacent fields of images F(n-1), F(n), and F(n+1) are read.

[0032] After that, enter step 102, perform motion detection on the point to be inserted in...

Abstract

The invention relates to the field of video processing and discloses a de-interlacing method and a de-interlacing device for interpolating pixel points. The method and the device perform edge detection, select points for participating in median filtering in the direction of a detected edge and make the margin of an inclined edge more clear on the premise of ensuring high capability of saw-teeth elimination and have the capability of inhibiting noises and high stability. Through motion detection, a static point to be inserted is directly, accurately and simply predicated according to a pixel value of a contiguous field at the position of the point to be inserted.

Description

technical field [0001] The invention relates to the field of video processing, in particular to the de-interlacing technology in post-decoding processing of computer video, digital TV and mobile multimedia video. Background technique [0002] Scanning The two scanning methods of the image display device include interlaced scanning and progressive scanning. Interlacing is used in ordinary television in that a picture is divided into two fields, which are displayed sequentially on the screen when a picture is displayed. These two fields may be called the top field and the bottom field, or the odd field and the even field. Progressive scan is used in computer monitors or digital televisions by displaying the entire frame at a time in units of an image frame, similar to the way frames are projected onto a screen in a motion graphics slideshow. [0003] De-interlacing is a method of converting an interlaced image signal into a progressive image signal. At present, many studies...
