  • Publication number: 20070216819
    Abstract: The invention provides methods and systems for processing image data made up of a series of frames for displaying on a dual modulation display system having a first modulator disposed to illuminate a second modulator, wherein a first modulation signal and a luminance map are not calculated for every frame. Instead, certain frames referred to as “key frames” are used to provide the first modulation signal and the luminance map for a plurality of other frames.

  • Publication number: 20070146257
    Abstract: A display has a screen which incorporates a light modulator. The screen may be a front projection screen or a rear-projection screen. The screen is illuminated with light from a light source comprising an array of controllable light-emitters. The controllable-emitters and elements of the light modulator may be controlled to adjust the intensity of light emanating from corresponding areas on the screen. The display may provide a high dynamic range.

  • Publication number: 20070002164
    Abstract: A method for capturing multiple sets of image data with an electronic camera having a shutter and an electronic shutter for selectively allowing light to reach an image sensor comprises opening the shutter and the electronic shutter, allowing light to reach the image sensor for a first exposure time, closing the electronic shutter, reading out pixel data captured during the first exposure time, allowing light to reach the image sensor for a second exposure time, and, reading out pixel data captured during the second exposure time. The method may be used to obtain multiple differently exposed images of a scene for combination into a high dynamic range image.
