    摘要: 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.

    摘要: A system comprises active magnetic emitters positioned within an area, passive magnetic emitters configured to be moved within the area, a magnetic field detector configured to measure a strength and direction of a magnetic field within the area, and a processor in communication with the magnetic field detector. The passive magnetic emitters are configured to be integrated in, coupled to, or secured to at least one tracked object or tracked subject within the area. The processor is configured to evaluate at least one change in the measured strength and direction of the magnetic field end send a signal to a visual effect actuator or visual effects display to initiate a visual effect based on the at least one change. A method and computer program product relating to the system is also provided.

    摘要: Systems and methods described herein are directed to capturing intrinsic color images of subjects. A camera may be equipped with a light source that is coaxial to the camera's image sensor and configured to emit a pulse of light of short duration. During image capture of a subject, the camera light source may emit the pulse of light through the lens barrel of the camera and stop emission of light before the reflected light from the light source returns. Thereafter, the camera lens receives the reflected light from the light source (with the light source no longer emitting light) and charge is collected at one or more image sensor photodetector sites of the camera.
