Abstract

The invention provides an image processing method and device and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps: firstly obtaining a preview image collected by a camera device; determining a normal exposure image according to the preview image, wherein the exposure value of the target area in the normal exposure image is the optimalexposure value; determining the exposure degree of the background area in the normal exposure image through the adjacent exposure image of the normal exposure image; finally, determining a target exposure image according to the exposure degree, carrying out fusion processing on the target exposure image and the normal exposure image, and determining a target fusion image as a shot image of the camera device. According to the embodiment of the invention, the technical problems that an existing common night scene HDR algorithm is directly applied to a night scene selfie scene, an image with anoptimal selfie effect cannot be shot, and the algorithm processing time is relatively long, so the user experience is relatively poor can be alleviated.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and electronic equipment. Background technique [0002] With the development of mobile phone camera functions, users' demand for camera modules is also increasing. For users who like to take selfies, it is very attractive to be able to take selfies with good quality in night scenes. However, most of the night scene selfie algorithms currently on the market use algorithms similar to ordinary night scene HDR (High-Dynamic Range, high dynamic range images). This algorithm can obtain a result image with a good overall dynamic range, but there are many problems when this type of algorithm is directly applied to night scene selfie scenes. First of all, it cannot guarantee that the best exposure image of the portrait must appear in the captured EV image, for example: camera module shooting The images with three ev spans of ev+2, ev+1...
