SYNCHRONIZATION METHOD AND SYSTEM FOR CAMERAS OF CAMERA-BASED TOUCH SCREEN

摘要

The present invention provides a synchronization method and system for cameras of a camera-based touch screen. The method is applied to the camera-based touch screen which includes at least two cameras and a control board for providing clock signals to the at least two cameras. The method includes: generating and sending, to the at least two cameras, initialization data for initializing the at least two cameras; generating and sending, to the at least two cameras, sleep entry indication signals for indicating that the at least two cameras should enter a sleep mode; and generating and sending, to the at least two cameras, sleep quit indication signals for indicating that the at least two cameras should quit the sleep mode. The invention can implement synchronous shoots for the cameras of the camera-based touch screen, thus improving the positioning accuracy of the touch object on the camera-based touch screen.
