摘要： Embodiments of this application provide a video recording method and a related apparatus. The method includes: displaying a first interface including a first window, where pictures acquired by a camera in real time and tracking identities are displayed in the first window; receiving a first operation for a first tracking identity; displaying a second interface in response to the first operation, where the second interface includes the first window and a second window, a part of pictures related to a first object in the first window are displayed in the second window, and the first object is an object corresponding to the first tracking identity; detecting, at a first moment, that the first object is displayed at a first position of the first window, and detecting, at a second moment, that the first object is displayed at a second position of the first window; and displaying, at both the first moment and the second moment, a part of pictures related to the first object in the second window. In this way, a tracking target is set based on a tracking identity. After the tracking target is set, pictures corresponding to the tracking target may be additionally obtained and displayed, to additionally obtain a video corresponding to the tracking target. In this way, a subsequent editing operation of a user can be reduced, thereby improving editing efficiency.

摘要： An information processing system (10) comprises: a distance acquisition unit (110) that specifies an iris area containing an iris of a target from a visible-light image of the target, and acquires an iris distance that is a distance to the iris area; an iris image acquisition unit (120) that acquires an iris image of the target by changing a focal length according to the iris distance; a score computing unit (130) that calculates a score relating to deviation of a focus in the iris image, based on the iris image; and a correlation update unit (140) that updates correlation between the iris distance and the focal length at a moment of acquisition of the iris image, based on the score. According to such an information processing system, since the correlation is updated with good accuracy, it is possible to acquire the appropriate iris image.

摘要： A video processing method and a terminal are provided. In the method, according to technical solutions provided in this application, after determining to record a main character, the terminal may simultaneously generate two videos. One video is a main-character video, and the other is an original video. To obtain the two videos in real time (the original video and the main-character video), first audio data needs to be copied to obtain two paths of second audio data, and the two paths of second audio data are concurrently encoded to generate the two videos in real time.

摘要： An adjustable-focus PV (picture/video) camera in a mixed-reality head-mounted display (HMD) device operates with an auto-focus subsystem that is configured to be triggered based on location and motion of a user's hands to reduce the occurrence of auto-focus hunting during camera operations. The HMD device is equipped with a depth sensor that is configured to capture depth data from the surrounding physical environment to detect and track the user's hand location, movements, and gestures in three-dimensions. The hand tracking data from the depth sensor may be assessed to determine hand characteristics - such as which of the user's hands or part of a hand is detected, its size, motion, speed, etc. - within a particular region of interest (ROI) in the field of view of the PV camera. The auto-focus subsystem uses the assessed hand characteristics as an input to control auto-focus of the PV camera to reduce auto-focus hunting occurrences.

摘要： This application provides a camera switching method and an electronic device, and relates to the field of terminal technologies, to alleviate a problem of reliance on a ranging component in a scenario in which a camera is switched with a photographing distance. A specific solution is as follows: An electronic device receives a first operation of a user, where a first value is a minimum focusing distance of a first camera. In a scenario in which an actual photographing distance is less than the first value, the electronic device displays a first interface in response to the first operation, where the first interface is used to display an image frame captured by the first camera. When the electronic device determines that a first condition is met, the electronic device displays a second interface, where the second interface is a preview framing interface used by the electronic device for photographing, the second interface is used to display an image frame captured by a second camera, and a short focus of the second camera is less than the first value. The first condition includes: a focusing status of the first camera is that focusing fails, and a sum of a defocus value of the first camera and a corresponding second value is less than a preset first threshold.
