Abstract: Embodiments of this application disclose a video image processing method and apparatus. A specific solution is as follows: obtaining identity information and location information of each subject in an ith video image frame; determining M main subjects from the ith video image frame based on identity information of subjects in N video image frames before the ith video image frame, where the identity information of the subjects in the N video image frames includes identity information of the M main subjects; cropping the ith video image frame based on location information of the main subjects, where a cropped ith video image frame includes the M main subjects; and scaling down or scaling up the cropped ith video image frame, so that a display displays the cropped ith video image frame based on a preset display specification.
