Abstract

The invention discloses an image processing method, an image processing device, a storage medium and a mobile terminal. The image processing method is applied to the mobile terminal and comprises thesteps of: acquiring an original image collected by the mobile terminal, wherein the color depth of the original image is at least 10 bits per pixel; determining a brightest region in the original image, and performing exposure processing on the brightest region to obtain intermediate image data; and performing logarithm conversion on the intermediate image data to obtain a target image. Accordingto the image processing method of the invention, gamma correction does not need to be carried out on the intermediate image data, but logarithm conversion is carried out, and more detail features of bright parts and dark parts of the image are reserved by using logarithm conversion; and on the other hand, exposure processing is carried out according to the brightest region, detail feature loss isavoided, and more detail features are reserved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to an image processing method, device, storage medium and mobile terminal. Background technique [0002] At present, in the process of obtaining image data or video data by mobile terminals, there will be a gamma correction link. The main purpose of this link is to compensate the characteristics of human vision, so that according to human perception of light or black and white, Maximize the use of data bits or bandwidth to represent black and white. Specifically, the dark part and the light part in the image signal are detected, and the ratio of the two is increased, so as to improve the image contrast effect, so as to conform to the perceptual characteristics of human vision. However, due to the characteristics of gamma correction, the performance of the bright and dark parts of the image will be poor, resulting in the loss of many details. Therefore, many de...
