The invention relates to a method for accelerating image network suspension speed, and a relative device, wherein present technique commonly do not consider the content of input image, which will generate mesh point for each pixel, via the error disperse method; and the invention can recognize the image content, that generates mesh point based on the size of pixel gray, for the pixel formed by black and white points, and generates mesh point via error disperse for the pixels in other rows. And the inventive device (1) comprises: gray comparing circuit (2), a recognize circuit (3), a gray buffer (6), a control circuit (9), a mesh point generator (7), an error disperser (8), and a multi-path selector (10), while the control circuit (9) selects circuit via error disperse method. The invention uses error disperses algorism to improve the network suspension speed. |
