Problems solved by technology

[0003] In practice, it is found that the memory space occupied by storing bitmap images is relatively large, and a bitmap of one pixel occupies 4 bytes of memory. For a 1080P mobile phone, a full-screen bitmap needs to occupy 8M of memory. The overhead of bandwidth and bandwidth are very large, which affects the processing efficiency of the terminal in the process of image processing

Abstract

The embodiment of the present invention provides an image processing method and device, wherein the method comprises the steps of using a graphics processing unit (GPU) to receive a rendering instruction sent by a central processing unit (CPU), wherein the rendering instruction is used to indicate the GPU to render a compressed image, and the compressed image is obtained by compressing a coded image; using the GPU to receive the compressed image sent by the CPU; using the GPU to render the compressed image. According to the present invention, the memory space of a terminal for storing images can be saved, the image processing efficiency and the terminal operation performance are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] At present, many application apps use a large number of images in order to achieve gorgeous and exquisite visual effects. Most of the existing image rendering technologies are to decode images in various image formats (such as PNG, JPG, etc.) to obtain corresponding bitmap images, and then the central processing unit (Central Processing Unit, CPU for short) of the terminal converts the bitmap The image is sent to the rendering engine for rendering. [0003] In practice, it is found that the memory space occupied by storing bitmap images is relatively large, and a bitmap of one pixel occupies 4 bytes of memory. For a 1080P mobile phone, a full-screen bitmap needs to occupy 8M of memory. The overhead of bandwidth and bandwidth are very large, thus affecting the processing efficiency of the termi...
