Abstract

Embodiments of the present application provide a wide dynamic range adjustment method and device, a storage medium, and an electronic device. The method includes: acquiring multiple exposure images in the same scene at the same time; Noise reduction processing, wherein each exposure image corresponds to a value of a first parameter, and the value of the first parameter is related to the second parameter corresponding to the raw data of the previous frame corresponding to the exposure image in the wide dynamic fusion process, The value of the second parameter has a mapping relationship with the brightness interval distribution of the previous frame original data corresponding to the exposure image; obtain the values ​​of the second parameters corresponding to the current frame original data corresponding to multiple exposure images in the wide dynamic fusion process , the multiple exposure images are fused to obtain a wide dynamic fusion image, which solves the problem that the wide dynamic adjustment and image noise reduction operations in the prior art are independent of each other and only operate on a single image, resulting in a small wide dynamic range and unsatisfactory noise reduction effect question.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a wide dynamic adjustment method and device, a storage medium, and an electronic device. Background technique [0002] Wide dynamic noise reduction is mainly used in the field of video and image technology to optimize the noise reduction effect of video images and improve the visual perception of video images. In the prior art, when it is identified that wide dynamic adjustment is required, noise reduction is performed first, and then dynamic range adjustment is performed. The two operate independently, and only perform noise reduction + wide dynamic adjustment on a single picture. The wide dynamic range is small and the noise reduction effect is not ideal. [0003] In the related art, the WDR adjustment and image noise reduction operations are independent of each other and only operate on a single image, resulting in a small WDR range and an unsatisfacto...
