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

[0029] 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 even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in each claim of the present application can also be realized.

[0030] 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.

[0031] 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.

[0032] In step 101, three adjacent fields of images F(n-1), F(n), and F(n+1) are read.

[0033] After that, enter step 102, perform motion detection on the point to be inserted ...

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 involves the field of video processing, which specializes in computer videos, digital TVs, and mobile multimedia video decoding. Background technique [0002] The two scanning methods of the scan image display device include interval scanning and rolling scanning.The interval scan is used for ordinary TV. The method is that one image is divided into two fields. These fields are displayed on the screen when displaying one image.These two fields can be called top and off -site, or strange fields and puppet fields.Scanned by rolling for computer displays or digital televisions. The method is to display the entire frame at a time through a unit of an image frame that is similar to the frame that is similar to the framework of the motion graphic slide to the screen. [0003] De-intervalia is a method of converting the image signal of the interval scanning into an image signal scanned by line.At present, many studies have proposed various ways to go...
