This application is applicable to the technical field of image processing, and provides an image capturing method, an image capturing device, a mobile terminal and a storage medium, including: obtaining the scene category of the current shooting scene; if the scene category of the current shooting scene is a polar night scene , then according to the brightness value of the preview image corresponding to the current shooting scene, the target exposure strategy and the target noise reduction model are obtained; based on the target exposure strategy, the current shooting scene is shot to obtain a candidate image; the candidate image is input to the target noise reduction model, and perform noise reduction processing on the candidate image through the target noise reduction model to obtain a target image. Through this application, high-quality images with higher definition and less noise can be obtained in extreme night scenes.
Description
technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image capturing method, an image capturing device, a mobile terminal and a storage medium. Background technique [0002] With the continuous development of imaging technology and mobile terminals, more and more users use mobile terminals to shoot images, and the requirements for shooting are getting higher and higher. Even at night when the ambient light is dark, they hope to obtain high-quality images. image. [0003] At present, in night scenes, most mobile terminals use a single night scene mode for shooting. A single night scene mode cannot be applied to all scenes, especially extreme night scenes. Due to the extremely dark surrounding environment, the clarity of the captured images may be reduced. Poor and noisy. Contents of the invention [0004] The present application provides an image capturing method, an image capturing device, a mo...
