Layer rendering processing method of video image and system thereof

Abstract

The invention discloses a layer rendering processing method of a video image and a system thereof. The method comprises the following steps of reading multi-layer data of a current video image frame and carrying out grouping processing on the read multi-layer data to obtain one or more layer groups, wherein the layer data in the same layer group is not mutually exclusive, and whether the layer data is mutually exclusive is at least partially based on whether the layer data in the layer groups is overlapped or is at least partially determined based on a floating point value corresponding to a single channel color of the overlapped layer data before blending and a floating point value corresponding to the single channel color of the overlapped layer data after blending; carrying out pixel parallel rendering processing on the one or more layer groups. By using the method and the system of the invention, target maximization of visual elegance, design flexibility, and real-time processing can be realized.

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
