Abstract

The embodiment of the invention provides an image definition improving method and device, electronic equipment and a readable storage medium, and relates to the technical field of image processing. The method comprises the steps of obtaining a first filtering image corresponding to an original image through smooth filtering processing; obtaining a first weight of each pixel point according to thepixel value difference between the corresponding pixel points of the original image and the first filtered image, wherein the larger the pixel value difference between the pixel points is, the largerthe first weight is; and sharpening each pixel point in the original image according to the first weight of each pixel point to obtain a first image. Therefore, the image is kept natural while the image definition is improved.

Description

Technical field[0001]This application relates to the field of image processing technology, and in particular to a method, device, electronic device, and readable storage medium for improving image definition.Background technique[0002]Limited by shooting requirements or shooting environment, unclear images may be obtained. For unclear images, sharpening methods are generally used to enhance the clarity of unclear images to ensure the image display effect. However, when the sharpening is performed, each pixel is sharpened according to the same weight 1, which will increase the noise of the image and cause the image edge to be unnatural.Summary of the invention[0003]In view of this, the purpose of this application is to provide an image definition improvement method, device, electronic device and readable storage medium, which can avoid the unnatural image that occurs when each pixel is sharpened according to the same weight 1. , To keep the image natural while enhancing the clarity of...
