Embodiment Construction

[0033] The following description will be made in conjunction with the accompanying drawings and specific implementation manners.

[0034] figure 1 It is a flow chart of an embodiment of an image coding processing method of the present application. see figure 1 , the method for image coding processing includes the following steps:

[0035] Step S101: The terminal obtains all image blocks that have changed in the source image of the current frame compared with the image of the previous frame.

[0036] When the terminal needs to share images with other terminals, such as when the terminal needs to let other terminals display the content on the terminal screen in real time or need to send the stored image to other terminals, the terminal obtains the source image of the current frame and sends the current frame The source image of the current frame is compared with the previous frame image to determine all changed image blocks in the source image of the current frame compared wi...

Abstract

The invention discloses a method, device and terminal for image encoding and decoding processing. The method for image encoding and decoding processing comprises the following steps that all image blocks, which change compared with an image of a previous frame, in a source image of a current frame are acquired, wherein the image blocks are part of images in the source image of the current frame; location information of the changed image blocks in the source image of the current frame is acquired; pixels of the changed image blocks and the location information of the changed image blocks in the source image of the current frame are encoded, and then encoded data of the image of the current frame are acquired. Through the mode, data volume of image transmission can be reduced, image encoding time is reduced, and real-time sharing of the images can be achieved on an ordinary terminal.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image encoding and decoding method, device and terminal. Background technique [0002] In the current era of information sharing, people can remotely share information on their terminals with friends at any time. Visual information sharing, especially the sharing of a series of high-definition images and videos, is very popular among people. However, for high-definition images, the amount of data occupied when sending them is large. For example, for a 1280*720 24-bit (bit) RGB true-color image, if the entire image is directly transmitted, it needs to transmit 2.63 megabytes section (Mbyte). [0003] In the prior art, images are generally encoded and compressed for retransmission. A relatively advanced compression method in image compression is the Joint Photographic Experts Group (JPEG) compression technology. JPEG compression technology is a lossy compr...
