Abstract

The application provides a night scene image processing method and device, an electronic device and a storage medium, belonging to the technical field of imaging. The night scene image processing method comprises the following steps: collecting multiple frames of images in sequence according to a preset exposure compensation mode; using a preset image recognition model to perform recognition processing on a preset frame of image in the multiple frames of images, so as to determine a target area and a non-target area in the preset frame of image; and using different noise reduction parameter values to perform noise reduction on the target areas and the non-target areas of the multiple frames of images, so as to generate a target image, wherein the value of the noise reduction parameter corresponding to the target area is greater than the value of the noise reduction parameter corresponding to the non-target area. Through the night scene image processing method, the overall noise reduction effect of the image and the purity degree of the target area are ensured, and the details of the non-target area are better preserved; therefore, the quality of the captured image is improved, andthe user experience is improved.

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular to a night scene image processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of science and technology, smart mobile terminals (such as smart phones, tablet computers, etc.) are becoming more and more popular. Most smartphones and tablet computers have built-in cameras, and with the enhancement of mobile terminal processing capabilities and the development of camera technology, the performance of built-in cameras is becoming more and more powerful, and the quality of captured images is also getting higher and higher. Mobile terminals are now easy to operate and portable, and it has become a norm for people to take pictures with mobile terminals such as smart phones and tablet computers in daily life. [0003] While smart mobile terminals bring convenience to people's daily photography, people's requirem...
