Method for improving image network transmission efficiency

The invention discloses a method for improving the transmission efficiency of an image network, which comprises the following steps that: S1: a client constructs a memory buffer area, and temporarily stores N frames of screenshots which are intercepted before a current frame, and N is greater than or equal to 1; s2, when the current frame needs to be transmitted, capturing a screenshot of the current frame, and comparing the screenshot with a screenshot of a previous frame; s3, segmenting the screenshot of the current frame and the screenshot of the previous frame of the current frame into a plurality of image blocks; s4, scanning and comparing the image blocks at the same position to obtain a changed area, intercepting the changed area, and obtaining an intercepted area and a corresponding position coordinate; s5, after scanning comparison of all the image blocks is finished, all the intercepted areas and corresponding position coordinates are obtained; and S6, compressing all the intercepted areas and the p
