Embodiment Construction

[0027] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0028] In the related art, when shooting an image in a night scene, because the light is relatively dark, the image is usually obtained by increasing the sensitivity value, however, using a high sensitivity value during the shooting process will introduce noise, resulting in blurred images. As a result, images captured in night scene scenes have poor imaging quality and high noise levels, which affect user experience.

[0029] In view of the above problems, the present application proposes an image noise reduction method. By...

Abstract

A method for image noise reduction method, device, computer readable storage medium and electronic device are provided.The method comprises the following steps of: acquiring multiple frames of original images, screening the multiple frames of original images according to the definition of the multiple frames of original images, retaining the clear target images, determining the noise suppression degree according to the number of frames of the screened original images, and finally synthesizing and denoising the retained target images according to the noise suppression degree. As a result, the noise suppression degree is determined according to the number of frames screened out from a plurality of original images, and the reserved images are synthesized and denoised according to the determined noise suppression degree, which not only effectively reduces the noise of the images and retains the information of the images to the maximum extent, but also improves the quality of the photographed images and improves the user experience.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image noise reduction method, device, computer-readable storage medium, and electronic equipment. Background technique [0002] With the development of smart terminal technology, the use of mobile terminal devices (such as smart phones, tablet computers, etc.) is becoming more and more popular. Most mobile terminal devices have built-in cameras, and with the enhancement of mobile terminal processing capabilities and the development of camera technology, the quality of captured images is getting higher and higher. Nowadays, mobile terminal devices are easy to operate and easy to carry. In daily life, more and more users use mobile terminal devices such as smartphones and tablet computers to take images, and the requirements for photo quality are getting higher and higher. [0003] However, due to the limitation of the shooting scene, especially in the sp...
