  • Patent number: 5626410
    Abstract: A novel rear projection screen that displays images with substantially uniform brightness over a wider field-of-view than prior rear projection screens, comprising a first diffusing assembly for diffusing the image and a second diffusing assembly for further diffusing the image from the first diffuser. In the preferred embodiment, the first and second diffusing assemblies comprise an input diffusing screen and a fiber optic array, respectively, with an output diffusing screen used at the output end of the fiber optic array. A preferred flat panel tiled display system that incorporates the present invention includes a plurality of collimated light sources, with respective liquid crystal display assemblies that impart images onto the collimated light beams. An imager images the image-bearing light beams onto the rear projection screen described above so that they are displayed in a tiled arrangement.

  • Patent number: 4720871
    Abstract: A method and apparatus for processing digital data representative of a digital array of points of a source image including a source image memory (12) or digitized camera (40) for providing a source image as a digital array of points, with provision for generating an end of array, or end of frame signal, (32) each time that the array has been computationally adjusted and transferred to a destination image memory. A control processor (14) includes a convolution kernel algorithm having the elements thereof configured for establishing a computational sequence or offset (18, 10) for each point in the array relative to a reference point, with each element having a constant value for computational adjustment of the array for each frame time represented by that element.
