The invention relates to an image processing method and device, computer equipment and a storage medium. The method comprises the steps of obtaining YUV image data; Copying the YUV image data from a central processing unit memory to a graphics processing unit memory; Converting the YUV image data into RGB image data in parallel in the memory of the graphic processor; Carrying out image beautifyingoperation on the RGB image data to obtain beautified RGB image data; Converting the beautified RGB image data into final YUV image data in parallel; And outputting the final YUV image data. By adopting the method, final YUV image data can be output, the image processing time of equipment is shortened, and the image processing efficiency is improved.
