Image processing method, apparatus and system

Abstract

Embodiments of the invention provide an image processing method, apparatus and system. The method comprises the steps that a central processing unit (CPU) writes first image data corresponding to a first image in a first buffer region; and the CPU writes second image data corresponding to a second image in a second buffer region, so that an image processor can conveniently perform superposition processing on the first image and the second image based on the first image data and the second image data. According to the image processing method, apparatus and system provided by the embodiments of the invention, the image processing can be finished only by two buffer regions while a UI thread and a browser engine are ensured to be independently refreshed, so that the memory consumption is reduced; and in addition, the image data is processed by the image processor instead of the CPU, so that the transmission time of the data on a bus is shortened, the image processing speed is increased, and the CPU burden is reduced.

Description

technical field [0001] The present invention relates to the field of computers, in particular to an image processing method, device and system. Background technique [0002] Currently, the display resolution requirements of display devices are getting higher and higher, while the processing capabilities of embedded devices (such as set-top boxes and smart TVs) are weak. Therefore, it is very important to improve the display performance of images. In order to reduce the refresh waiting time of the browser engine, the prior art uses at least two shared buffers (share buffer) to store webpage images, which greatly increases the usage of memory. In addition, the browser engine writes the webpage images into the shared buffer Finally, the UI (User Interface, user interface) thread of the browser also needs to read the webpage image from the shared buffer, and output it to the display device after superimposing it with the local image, which also increases the time for image proce...

In order to reduce the refresh waiting time of the browser engine, the prior art uses at least two shared buffers (share buffer) to store webpage images, which greatly increases the usage of memory. In addition, the browser engine writes the webpage images into the shared buffer Finally, the UI (User Interface, user interface) thread of the browser also needs to read the webpage image from the shared buffer, and output it to the display device after superimposing it with the local image, which also increases the time for image processing.
