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.

Slow-motion video shooting method and electronic device

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.

A content push method is provided. The method is applied to a terminal, which includes a first set of cameras. The method includes: when the terminal is in a screen-locked state and an off-screen is woken up, capturing a first set of face images of a user by using the first set of cameras; determining whether the first set of face images matches a registered user; if the first set of face images matches the registered user, performing, by the terminal, an unlocking operation, and determining a facial attribute of the user based on the first set of face images; determining a to-be-pushed media resource based on the facial attribute; and pushing the media resource in an interface displayed after the terminal is unlocked.

Content push method and apparatus, and device

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.
