Abstract

The invention belongs to the technical field of mobile terminals, and provides a high-dynamic-range image acquisition method, a device, a mobile terminal and a computer-readable storage medium, the method comprises: when a moving object exists in a shooting scene, shooting N frames of images on the shooting scene, wherein N is an integer greater than 1; Acquiring a quality evaluation value of eachof the N frames of images, wherein the quality evaluation value indicates a picture quality of the image; If there is an image whose quality evaluation value is higher than a preset threshold value in the N-frame image, obtaining a target image according to the image whose quality evaluation value is higher than the preset threshold value, wherein the target image is a high dynamic range image. With the present application, ghost shadows in high dynamic range images can be avoided, and picture quality of the high dynamic range images can be improved.

Description

technical field [0001] The present application belongs to the technical field of mobile terminals, and in particular relates to a high dynamic range image acquisition method, device, mobile terminal and computer-readable storage medium. Background technique [0002] With the popularization of mobile terminals such as mobile phones and tablet computers, the shooting function of mobile terminals has been widely used. High dynamic range images can provide more dynamic range and image detail than ordinary images. In order to obtain a high dynamic range image, usually multiple frames of images are obtained by continuous shooting of a shooting scene, and the multiple frames of images are synthesized. However, when there is a moving object in the shooting scene, the content of multiple frames of images will change, which will lead to ghosting in the final composite high dynamic range image, reducing the picture quality of the high dynamic range image. Contents of the invention ...
