Abstract:
The disclosure is directed toward stabilizing an image projected by a projector in an environment including vibrations or other movements that displace the projected image. In one set of implementations, an image projected by a projector may be stabilized by using an image stabilization system that detects a displacement of the projector from an equilibrium position and controls an optical element of the projector to offset the displacement. In an additional set of implementations, an image projected by the projector may be stabilized by using an image stabilization system that measures a rate of displacement from equilibrium of an image projected by the projector to predict a displacement of the projector and counteract the predicted displacement. In another set of implementations, an image projected by a projector may be stabilized by precalculating a plurality of lookup tables that correct for displacements of the projected image during operation of the projector.
