Method, apparatus, device and storage medium for synthesizing high dynamic range images

Abstract

Embodiments of the present application relate to the technical field of image processing, and provide a method, device, device, and storage medium for synthesizing high dynamic range images, aiming to synthesize high dynamic range images with more uniform overall definition and improve image quality. The method includes: according to a predetermined correspondence between the number of images to be fused and the exposure modes, obtaining atlases to be fused corresponding to each of the multiple exposure modes, each atlas to be fused includes multiple frames with uniform overall brightness and overall information. an image to be fused with a uniform noise ratio; for each exposure mode in the multiple exposure modes, fuse each frame of the image to be fused in the atlas to be fused corresponding to the exposure mode to obtain the fusion corresponding to the exposure mode The fused images corresponding to different exposure modes have the same noise level; using the high dynamic range HDR algorithm, the fused images corresponding to the various exposure modes are synthesized into a high dynamic range image.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a method, apparatus, device, and storage medium for synthesizing a high dynamic range image. Background technique [0002] With the development of image processing technology and the popularization of electronic devices with shooting functions, more and more professional or non-professional users use electronic devices such as cameras, mobile phones, and tablet computers to shoot and record images. Some electronic devices run image processing software. After the user shoots the image, the image processing software automatically beautifies the image, thereby outputting the beautified image. Some electronic devices do not have image processing software installed. If the user needs to beautify the image after taking the image, it is usually necessary to import the image from the electronic device into other devices installed with image proce...

Problems solved by technology

However, in the high dynamic range image synthesized by the above method, the sharpness of the image in the bright area and the dark area is very different, resulting in the overall unbalanced sharpness of the image.
