Abstract

The present disclosure relates to the technical field of image processing, and relates to an image processing method, device, computer-readable medium, and terminal equipment. The method includes: acquiring the image to be processed and the corresponding underexposed image, and marking the highlighted area of ​​the image to be processed and the corresponding highlighted contrast area in the underexposed image; counting the corresponding pixel points between the highlighted area and the highlighted contrast area Grayscale difference to filter target pixels in the highlight area and highlight contrast area based on the grayscale difference; calculate the average brightness value of the target pixel in the highlight area and highlight contrast area Calculate the grayscale configuration coefficient; configure the fusion weight for the image to be processed and the underexposed image according to the grayscale configuration coefficient, and generate an intermediate image according to the image to be processed and the underexposed image after the configuration of the fusion weight; the image to be processed, the intermediate image and the underexposed image Perform fusion processing to obtain a fusion image. This method can effectively improve the image quality in extremely dark scenes.

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 a terminal device. Background technique [0002] With the continuous improvement of terminal technology, image processing solutions are also more abundant. For example, when shooting images or videos, the prior art provides multiple shooting modes, such as normal camera mode, portrait mode, panorama mode, etc.; in addition, for scenes with low brightness, a scene mode is also provided. However, for extremely dark scenes, even if there is a light source, the high light area will still be overexposed when shooting the image, resulting in low image quality and loss of local details of the image. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and t...
