Image processing method and device, computer readable medium and electronic equipment

Abstract

The invention provides an image processing method, an image processing device, a computer readable medium and electronic equipment, and relates to the technical field of image processing. The method comprises the steps of obtaining to-be-processed brightness data of a to-be-processed image, and determining a self-adaptive brightness data set based on a preset brightness parameter set and the to-be-processed brightness data; performing image processing on the to-be-processed brightness data and the to-be-processed image based on the adaptive brightness data set to obtain a target fusion image;and extracting fusion brightness data of the target fusion image and to-be-processed chrominance data of the to-be-processed image, and combining the fusion brightness data and the to-be-processed chrominance data to output a target image. According to the method, the image processing process can be controlled, the problem that the processing effect is uncontrollable due to the fact that the samedata is used for processing the images with different contents is avoided, meanwhile, different areas of the image to be processed can be locally adjusted, and the effect of increasing local image details is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image processing method, an image processing device, a computer-readable medium, and electronic equipment. Background technique [0002] In the era of rapid computer development, relying on mobile phones, digital cameras and other electronic devices to record life has become an indispensable part of human life. Compared with the human eye's ability to perceive the details of bright and dark areas at the same time, when the camera captures images, there is a greater limitation in the perception of brightness, so it cannot capture the details of bright and dark areas at the same time. Correspondingly, the image captured by the camera may contain overexposed bright areas or underexposed dark areas. For example, when shooting in the sun, the sunlit area is prone to overexposure, resulting in an overly bright area, while the non-sunlit area is prone to undere...

Problems solved by technology

[0003] The purpose of the present disclosure is to provide an image processing method, an image processing device, a computer-readable medium, and an electronic device, so as to at least adjust to a certain extent the problem of insufficient dynamic range of the image, so as to avoid problems caused by overexposure and underexposure in related technologies. Exposure and other problems cause loss of image details, image distortion and other problems
