The invention discloses an image processing method and device, a terminal and a storage medium, and belongs to the technical field of terminals. The method comprises the steps of keeping on shooting afirst video after a shooting function is enabled; extracting m frames of images from the first video, wherein the m frames of images are images of a target object shot in different angles; obtainingrespective corresponding quality score of the m frames of the images, wherein the quality score is used for indicating image quality of the image; selecting and displaying n candidate images from them frames of images based on respective corresponding quality score of the m frames of the images, wherein the candidate images are images with the quality score higher than a preset threshold. N high-quality candidate images which include the target object are output automatically through the terminal, and the subsequent users can select images satisfies the prospection from the displayed n candidate images, so that users are avoided adjusting shooting parameters every time the users shoot images, and the operational difficulty in shooting high-quality images is reduced greatly.
