Problems solved by technology

This method is firstly cumbersome and difficult for users to understand, and secondly, the efficiency is very low, because all images will be deinterleaved into two images of the same size for processing, which is equivalent to doubling the processing time

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0027] The present invention divides all video rendering special effects into two categories: pixel-based special effects (pixel-based special effects) and non-pixel-based special effects (non-pixel-based special effects).

[0028] The characteristic of Pixel-based special effects is that the output of the special effect has the same size and position as the input image, and for a given special effect parameter, if the input image is divided into many sub-images, then the results of applying the special effect to these sub-images respectively If the images are recombined into one image, the result of direct special effects processing on the image is the same as that of the original image. Color correction effects are typical Pixel-based effects. For pixel-based special effects, the present invention does not impose any additional requirements on...

Abstract

The invention relates to video image processing technology, in particular to an efficient high-quality video special effect rendering method. The method divides video processing special effects into special effects based on pixels and special effects not based on the pixels. Special effect rendering processing is treated differentially according to the two different special effect types and according to the fact whether input images are images based on a field. A high-quality special effect rendering mode accurate to the field is achieved without adding processing time apparently, and video image high-quality special effect rendering efficiency is improved.

Description

technical field [0001] The invention relates to video image processing technology, in particular to an efficient and high-quality rendering method for video special effects. Background technique [0002] Video post-production special effects processing and compositing software will provide users with a large number of video special effects so that users can perform various processing on videos, such as color correction, blurring, motion, deformation, sweeping and so on. In the field of post-processing and compositing of video effects, in addition to requiring these special effects to provide as many functions as possible, it is also necessary for these special effects to be rendered as fast as possible, because engineering users, whether for compositing or editing purposes, may Adding many special effects to the original material, if the speed of these special effects is very slow, it will make the user's adjustment very inefficient. In addition, images obtained from video ...
