Title: METHOD FOR TESTING PROJECTION DISPLAY SYSTEM, AND PROJECTOR
Abstract:
A method for testing a projection display system, and a projector. The method comprises: performing a Home point calibration on a projection display system, controlling the projection display system to perform an autofocus process to acquire a new focus parameter, then computing and generating a calibration parameter, and storing the calibration parameter; upon restart of the projection display system, employing the calibration parameter directly to focus in order to project an image. Therefore, the embodiment can achieve a better autofocus effect. The method may further comprise an autofocus test after the Home point calibration.
