Image processing method and device and image processing system

Abstract

The invention provides an image processing method and device and an image processing system, and the image processing method is applied to a first terminal and comprises the steps: dividing pixel points of a to-be-processed image into a plurality of ordered pixel groups according to a preset division rule, each pixel group comprises four pixel points, and each pixel point comprises brightness dataand chrominance data; generating first data and second data corresponding to each pixel group according to the brightness data and the chrominance data of the four pixel points in each pixel group; generating a first data set and a second data set corresponding to the to-be-processed image according to the first data and the second data corresponding to each pixel group of the to-be-processed image; respectively encoding the first data set and the second data set to obtain first encoded data and second encoded data corresponding to the to-be-processed image; and sending the first coded data and the second coded data to a second terminal. Through the method, complete data of each pixel is effectively stored to realize lossless coding of the image.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to an image processing method and device, an image processing system, a computing device, and a computer-readable storage medium. Background technique [0002] With the development of Internet technology, cloud computing technology is becoming more and more mature, and cloud games are also produced. When users play cloud games, the game screen is generated on the server, and the game image is sent to the client after encoding, and the client is decoded. Play the game screen. [0003] At present, when encoding game images, one encoding method is to convert the RGB format of the image to YUV444 format. This encoding conversion is a lossless conversion, but currently there are very few terminal devices on the market that support YUV444 format decoding, and users need to replace the terminal. Equipment to experience the game, the game cost for the user is too high, s...

[0003] At present, when encoding game images, one encoding method is to convert the RGB format of the image into YUV444 format. This encoding conversion is a lossless conversion, but currently the market There are very few terminal devices that support YUV444 format decoding on the Internet. Users need to replace terminal devices to experience the game. The game cost for users is too high, so the format conversion of YUV444 is not practical. Another method is to convert the RGB format of the image to YUV420 Format, the capacity of YUV420 format is smaller than that of RGB format, when encoding the image, part of the data will be lost, and the accuracy of the game screen image will be lost, which will greatly reduce the user's game experience
