Abstract: A facial expression editing method includes obtaining a to-be-edited image, where the to-be-edited image includes a first face image of a user; obtaining, by using a camera, a first video stream including a second face image of the user; editing the first face image of the user in the to-be-edited image based on the second face image of the user in the first video stream to obtain an edited image, where a facial expression of the user in the edited image is associated with a facial expression of the user in the first video stream.

Abstract: A method and an apparatus for obtaining an extended depth of field image, and an electronic device are disclosed. The method includes: determining a target focal length range based on an initial focal length (101), 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 (102); and registering and fusing, the plurality of images to obtain an extended depth of field image (103). The target focal length range of concern to a user is selected based on the initial focal length, so 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.

Abstract: An information displaying method for a terminal device, and a terminal device, where the method includes displaying, by the terminal device, prompt information on a screen of the terminal device when the terminal device is in a screen-locked state, collecting, by the terminal device, a user face image using a camera of the terminal device, and displaying, by the terminal device on the screen of the terminal device, content information corresponding to the prompt information when the user face image matches an image template stored in the terminal device. According to the information displaying method, related information is displayed through facial recognition without releasing the screen-locked state of a mobile phone such that convenience of information displaying is improved while information security is ensured.
