Abstract: A thumbnail-based image display method and terminal, where the method includes displaying a thumbnail on a screen, performing feature extraction on the thumbnail to obtain a feature factor of the thumbnail, displaying prompt information on the screen when the feature factor of the thumbnail is matched with a feature factor in a feature factor index library, where the feature factor index library indicates correspondences among feature factors and image storage addresses, obtaining an original image obtaining request, and displaying the original image on the screen based on the original image obtaining request. According to the method and terminal, feature indexes are created for all images in memories and buffers of all applications and in an image library, and an original high-resolution image is found using a feature factor of a thumbnail, thereby implementing high-definition image sharing between different applications.

Abstract: Embodiments of this application relate to the field of image processing and display technologies, and provide a method for image processing based on vertical synchronization signals and an electronic device, to shorten a response latency of the electronic device and improve fluency (such as a touch latency) of the electronic device. A specific solution includes: drawing, by the electronic device, one or more first layers in response to a first vertical synchronization signal, and rendering the one or more first layers, and after rendering the one or more first layers, performing layer composing on the rendered one or more first layers to obtain a first image frame; and refreshing and displaying the first image frame in response to a second vertical synchronization signal.

Abstract: A screen freezing processing method and a terminal are provided. The method includes: displaying a user interface of an application, and receiving an operation on the user interface, where the operation on the user interface is used to implement a first function; skipping responding to, by the terminal within first duration, the operation on the user interface, and skipping implementing the first function; and after the first duration, responding to, by the terminal, the operation on the user interface, and implementing the first function. This technical solution can automatically restore implementation of the first function, thereby improving user experience.

Abstract: A slow-motion video shooting method includes detecting that a preset motion occurs on a main object in a video stream; determining a first video clip in the video stream based on the preset motion; determining a first frame rate based on the preset motion; and processing the first video clip based on the first frame rate to obtain a second video clip, where a play time of the second video clip at a target play frame rate is greater than a collection time of the first video clip, and the first frame rate is greater than the target play frame rate. When a main object for shooting moves, the first video clip, for example, a highlight clip, is obtained from the video stream, so that an electronic device can accurately capture a highlight moment of the main object.

Abstract: An image processing method includes determining a target area and a background area in an image by performing mask segmentation on the image. Different color processing modes are applied to the target area and the background area, so that luminance of the target area is greater than luminance of the background area, or chrominance of the target area is greater than chrominance of the background area, and a main object corresponding to the target area is more prominently highlighted.

Different color processing modes are applied to the target area and the background area, such that luminance of the target area is greater than luminance of the background area, or chrominance of the target area is greater than chrominance of the background area, and a main object corresponding to the target area is more prominently highlighted. This enables a terminal user to have a movie special effect during photographing or video photographing, and improves photographing experience of the user. In addition, the present disclosure further provides a flicker elimination method, such that a color change of video content is smoother and more natural.

Abstract: A method and an apparatus for obtaining an extended depth of field image, where the method includes: determining a target focal length range based on an initial focal length, where the target focal length range includes the initial focal length; obtaining a plurality of images of a photographed object for a plurality of focal lengths in the target focal length range; and registering and fusing the plurality of images to obtain an extended depth of field image. The target focal length range of concern to a user is selected based on the initial focal length, such that there is no need to obtain images of all focal lengths of a lens, a quantity of obtained images and processing time of registration and fusion can be reduced.
