Secondary image mixing method and apparatus

Abstract

The invention provides a secondary image mixing method and a secondary image mixing apparatus. The method comprises the following steps: acquiring a first image from a first process; acquiring alpha value information and gray value information from the first image; performing a first preset processing on the alpha value information and a second preset processing on the gray value information, and storing the processed alpha value information and the processed gray value information into different channels of a texture map; performing FXAA processing on the texture map and a second image, and acquiring the RGB information of the second image and the alpha value information of the texture map according to the processing result to obtain a third image; inputting the third image into a second process and mixing the third image and a fourth image in the second process according to the alpha value information. By the method, the third image and the fourth image in the second process can be mixed well, and the phenomenon of jaggies occurring when the image is imported from one process to another process is greatly reduced, so that the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for secondary image mixing. Background technique [0002] Since the 1970s, as computer graphics have grown in complexity, rendering has become an increasingly important technique. Rendering is one of the most important research topics in 3D computer graphics and is closely related to other technologies in the practical field. In the graphics modeling pipeline, rendering is one of the important steps, through which the final display effect of the model and animation can be obtained. [0003] At present, image rendering is carried out in one process, and in the actual graphics modeling process, it is often necessary to import the image rendered by one process into another new process for use, but because the image cannot be used in the new process If the image background is well mixed, it will lead to serious aliasing, which is manifested as concave-convex alia...

Problems solved by technology

[0005] To this end, it is necessary to provide a technical solution for secondary image mixing to solve the problem that when the rendered image is imported from one process to another new process, the image cannot be well mixed with the image background in the new process, resulting in jagged Phenomenon, which affects the picture quality and brings bad sensory experience to users
