Abstract
Disclosed herein is a laser projection system including a laser projector emitting a laser beam, a movable mirror apparatus reflecting the laser beam toward a surface, and a graphics processing unit (GPU). The GPU is configured to receive video data, estimate a varying speed of movement of the movable mirror apparatus for different positions of the laser beam across the surface, and process the video data based upon the estimated varying speed of movement. An application specific integrated circuit (ASIC) receives the processed video data, and to generate a beam position control signal based upon required or desired movement of the movable mirror apparatus. A laser driver controls the laser projector as a function of the processed video data, and a mirror controller controls the movable mirror apparatus as a function of the beam position control signal.
