CONTROL METHOD AND APPARATUS FOR SYNCHRONOUS EXPOSURE OF MULTI-CAMERA SYSTEM, AND TERMINAL DEVICE

摘要

A control method and apparatus for the synchronous exposure of a multi-camera system, and a terminal device thereof, the control method comprising: after receiving a synchronous exposure instruction, acquiring initial hardware time codes of cameras in the multi-camera system so as to obtain a plurality of initial hardware time codes; determining a synchronous reference value according to the plurality of initial hardware time codes; determining a frame compensation value corresponding to each camera in the multi-camera system according to the synchronous reference value and the initial hardware time code of each camera; and sending the frame compensation value corresponding to each camera to each corresponding camera in the multi-camera system, so that the each camera adjusts the length of an image according to the corresponding frame compensation value thereof so that the exposure time of all cameras in the multi-camera system is synchronous. Employing the described solution may improve the precision of synchronous exposure of a plurality of cameras in the multi-camera system in a complex scene.
