Abstract: This application provides a method and an apparatus for controlling a light compensation time of a camera module. An example method includes: determining a first target area in a first image shot by a camera before a current frame; determining a first exposure time period of a first target photosensitive chip row in the current frame based on the first target area; and indicating, based on the first exposure time period, an infrared light source to perform light compensation in response to at least that the photosensitive chip is exposed in the current frame.

Abstract: The present disclosure relates to methods and apparatuses for identifying an object of interest of a user. One example method includes obtaining information about a line-of-sight-gazed region of the user and an environment image corresponding to the user, obtaining information about a first gaze region of the user in the environment image based on the environment image, where the first gaze region is used to indicate a sensitive region determined by using a physical feature of a human body, and obtaining a target gaze region of the user based on the information about the line-of-sight-gazed region and the information about the first gaze region. The gaze region is used to indicate a region in which a target object gazed by the user in the environment image is located.
