Image processing method and device, and readable storage medium

Abstract

The embodiment of the invention provides an image processing method and a device, and a readable storage medium, and the method comprises the steps: firstly determining a first pixel region accordingto a first pixel point in a first image; then, according to the first pixel area and the alignment vector between the first image and the second image under the sub-pixel precision, obtaining N secondpixel areas, corresponding to the first image, in the N second images; fusing the first pixel points and the second pixel points in the second pixel area based on the weight of the pixel distance andthe weight of the pixel value, completing the fusion of the first image and the N second images by traversing each pixel point in the first image, and obtaining a fused image. According to the method, under the sub-pixel precision, the first image and the second image are fused, and the images are filtered from the two aspects of the pixel distance and the pixel value, so that edge details in thefused images are better protected, image blurring is reduced, and a better visual effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and readable storage medium. Background technique [0002] Smart terminal devices such as mobile phones and IPADs have become indispensable electronic products in people's lives, and the camera function in smart terminal devices is also one of the key functions that people pay attention to and use. In order to improve the satisfaction of the shooting effect of the smart terminal device, using multiple frames of images to improve the image quality is a very effective processing method. [0003] In the traditional way, the processing method of multi-frame images is based on alignment and fusion at the pixel level. Although the above method can suppress the influence of noise, it will cause problems such as blurred edges, false colors and loss of details.
