Abstract

The invention discloses an image processing method, an image processing device, an image processing system and a storage medium. The image processing method is applied to the image processing device, and the image processing method comprises the following steps: obtaining image size information of an original image; obtaining a first processing block currently sent by the first image processing module, and block information and accumulation information corresponding to the first processing block; obtaining position information of the first processing block in the original image according to the image size information, the block information and the accumulation information; acquiring first error information according to the position information; and performing in-block error diffusion processing on the first processing block according to the first error information and an error diffusion template to obtain second error information. According to the scheme of the embodiment of the invention, when a high-resolution image is processed in hardware, error diffusion image processing of dynamic partitioning can be supported; under the condition that the image quality is guaranteed, the consumption of internal storage resources of hardware is reduced, and the occupied chip area during image processing is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and its device, system, and storage medium. Background technique [0002] With the development of information technology, the application range of images is becoming wider and wider. Using images to convey information is more intuitive and vivid, and saving images while ensuring image quality takes up a lot of memory. In the related art, when using the error diffusion dithering image processing technology to process an image, the processing is usually performed based on the entire image. The implementation of the existing error diffusion algorithm basically performs image processing on the basis of the entire image. After the template of the error diffusion algorithm is selected, the entire image is processed pixel by pixel. Take high-resolution image processing as an example, such as 4096*4096 pixel. When processing the error diffusi...
