  • Patent number: 10775688
    Abstract: Projector display systems comprising a light dimmer and first modulator are disclosed. The light dimmer may comprise an adjustable iris, adjustable light sources and/or LCD stack that is capable of lowering the luminance of the light source illuminated the first modulator. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the light dimmer and first modulator. The display system may render a desired dynamic range for rendering a projected image by a combination of such control signals.

  • Patent number: 7015942
    Abstract: Disclosed is a telecine system (300) for media conversion of an original format video signal to a new format video signal. The new format video signal is displayed on at least two monitors (303, 307) having different color gamuts so that a colorist (302) can adjust the telecine process in order to produce the new format video signal such that it has acceptable image quality on both of the monitors (303, 307).
