  • Patent number: 9384535
    Abstract: Methods and systems for reducing or eliminating perceived ghosting in stereoscopic three-dimensional (3D) image display are described. A stereoscopic image that includes image content can be received. Display system parameters can be received. A local region of the stereoscopic image can be identified using the image content. The local region can include ghosting. Psychovisual factors can be selected using the image content. A modified stereoscopic image can be generated from the stereoscopic image by reducing or eliminating the ghosting of the local region using the psychovisual factors and the display system parameters. The modified stereoscopic image can be outputted for display.

  • Patent number: 6582080
    Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for importing image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD). Reflective surfaces within the projector may be covered or coated with material that alters the polarization of reflected stray light from the defined orientation or depolarizes the reflected stray light.
