An image processing method and device

Abstract

The invention discloses an image processing method, which is used for increasing the image processing efficiency and comprises the steps of: acquiring image data of an image layer A and image data of an image layer B of a current frame, wherein the image data of a first image layer are linear data, and the first image layer and a second image layer are incompletely overlapped; when the acquired image data of the image layer B are updated relative to the image data of the image layer B in a register, determining acquired updated area in the image layer B; and merging the acquired image data of the image layer A and the acquired image data in the updated area in the image layer B, and substituting the image data of the image layer A in the register and the image data corresponding to the updated area. The invention also discloses a device for realizing the method.

Description

technical field [0001] The invention relates to the fields of computers and images, in particular to an image processing method and device. Background technique [0002] With the development of image technology, high-definition television, network video and camera monitoring have been widely popularized. The image that people watch on the display screen is usually composed of multiple image layers. [0003] Taking the player playing video as an example, the video is generally played on the upper part of the display screen, and the playback progress, time and volume are displayed on the lower part of the display screen. In fact, the upper part comes from the image layer (layer) A, and the lower part comes from the image layer B, and the two image layers are combined to obtain the image on the display screen. [0004] In the prior art, the image layer A of the first frame is combined with the image layer B of the first frame, and buffered in the buffer 1 . Then the image la...

AI Technical Summary

Problems solved by technology

If the image data of the image layer B is large, the image data of the image layer B cannot be written within the gap time, which may cause video delay or frame loss, and the playback quality of the video stream is poor

Or, there needs to be a large gap time between two adjacent frames of image layer A to ensure that the image data of image layer B is written into the buffer, resulting in a relatively low frame rate of image layer A
