  • Patent number: 5742274
    Abstract: A video interface system which samples an input video signal to capture a subset of pixels from first and second frames of the signal. A frame buffer temporarily stores the captured subsets of pixels from the first and second frames and a display interface unit reads the stored pixels out of the frame buffer for transfer to a flat panel display. The subsets of pixels from the first and second frames are interleaved on the display to provide a video image. The display is updated by replacing one of the displayed subsets of pixels with a subset of pixels captured from a subsequent frame of the video signal. In one embodiment, the subset of captured pixels from the first frame includes those pixels for which the sum of the respective row and column numbers is either odd or even and the subset of captured pixels from the second frame includes those pixels for which the sum of the respective row and column numbers is even or odd.
