Abstract
A light projection system includes a GPU that receives video data containing video images, defines a two-dimensional grid (each element of which represents a position of a light beam at a different time), designates which elements of the two-dimensional grid correspond to positions of the light beam in a designated area, designates which elements correspond to positions of the light beam outside of the designated area with some positions outside being designated as calibration positions, maps each element corresponding to positions in the designated area to a corresponding pixel of a frame of a video image, and maps elements corresponding to calibration positions to calibration pixels. An ASIC receives the mapped pixels and mapped calibration pixels from the GPU, and generates a beam position control signal therefrom. A controller controls a movable mirror based on the beam position control signal.
