Layer rendering processing method and system for video image

Abstract

The present application discloses a video image layer rendering processing method and system thereof, wherein the method includes: reading multi-layer layer data of the current video image frame, grouping the read multi-layer layer data to obtain one or Multiple layer groups; wherein the layer data in the same layer group are not mutually exclusive, and whether the layer data are mutually exclusive depends at least partly on whether the layer data in the layer group overlaps, or at least partly depends on the overlapping Determine the floating-point value corresponding to the single-channel color of the layer data before mixing and the floating-point value corresponding to the single-channel color of the overlapping layer data after mixing; perform pixel parallel rendering on the one or more layer groups deal with. Through this application, the three goals of visual elegance, design flexibility and real-time processing can be maximized.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a layer rendering processing method and system for video images. Background technique [0002] With the popularization of portable mobile terminal devices such as smartphones and cameras, more hardware manufacturers or mobile app developers hope that mobile terminal devices have strong video / image special effects processing performance, for example, they hope to synthesize animations while shooting videos. However, the richer and more realistic animations often use more layers. According to the traditional synthesis method, animations with a large number of layers are difficult to meet the needs of real-time processing. Therefore, in the process of synthesis, how to balance the effect and efficiency of the algorithm, while satisfying the real-time performance without destroying the exquisiteness of the vision, is a problem that needs to be solved.

Problems solved by technology

However, the purely GPU parallel rendering method is difficult to achieve the most flexible and rich blending modes for the overlapping areas of different layers

If you want different layers to have their own unique blending modes (such as custom lighting, overlay, etc., these effects are sensitive to the composition order of layers), for multi-layer overlapping areas, the effect after GPU parallel rendering is compared to traditional Layered iterations, often with color deviation, cannot meet the original visual design requirements
