Embodiment Construction

[0035] 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.

[0036] In the prior art, in order to improve the imaging quality when shooting a night scene, multiple frames of images are usually collected and then aligned to perform noise reduction. However, the multi-frame image processing process is relatively complicated, involving multiple links such as multi-frame alignment, motion detection, temporal and spatial domain noise reduction, high dynamic range synthesis, and tone mapping. It needs to be held steady for more than 4 seconds to draw a picture, and the experience is not fri...

Abstract

The present application provides a night scene image processing method, device, electronic device, and storage medium, wherein the method includes: by collecting multiple frames of original images, and according to at least two frames of the first image, generating a multi-frame noise reduction to obtain synthetic noise reduction The first task of the image, according to the target image selected from at least two frames of the first image and at least one frame of the second image, generate a second task for determining high dynamic synthesis weight information, and execute the first task and execute the second task in parallel , synthesizing at least one frame of the second image and the synthesized noise reduction image according to the high dynamic synthesis weight information determined by the second task to obtain a high dynamic range image. Therefore, by executing the first task and executing the second task in parallel, the synthetic noise reduction image and the generation of high dynamic synthetic weight information are processed in parallel, thereby shortening the image processing time, improving the night scene image processing speed, and improving night scene imaging. Speed, improve the user's photo experience.

Description
