Title:
IMAGE PROCESSING METHOD, DEVICE AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/028700
Kind Code:
A1
Abstract:
Provided are an image processing method, a device and a computer readable storage medium, the method comprising: preprocessing an original image to obtain a first image (S101); decomposing the first image into a plurality of first sub-images (S102); determining detail information, color information, and mean value information of each of the plurality of first sub-images (S103); compressing the plurality of first sub-images to generate a plurality of second sub-images according to the detail information, the color information, and the mean value information (S104); and determining a target image according to the plurality of second sub-images (S105). When performing a tone mapping on a high dynamic range image, it is not just to perform tone mapping on the luminance information, but to compress the detail information, the color information, and the mean value information simultaneously. This ensures that the low dynamic range image after the tone mapping processing can retain color information of the high dynamic range image, avoiding the low dynamic range image from producing an shift in color compared to the high dynamic range image.
