Abstract

A focusing control method is performed by a focus-to-be-adjusted device. The focusing control method includes: during a current focusing process of the focus-to-be-adjusted device, obtaining (S110) current magnetic encoder data of the focus-to-be-adjusted device and a first focusing motor movement direction during a previous focusing process; determining (S120) target magnetic encoder data corresponding to the current focusing process, where the target magnetic encoder data represents magnetic encoder data, during the current focusing process, at which a projected image is in focus; and controlling (S130) the focus-to-be-adjusted device to perform focusing based on the current magnetic encoder data, the target magnetic encoder data, and the first focusing motor movement direction.
