ABSTRACT:
Method and apparatus for providing high resolution images for static display of document pages that are scanned in through a document scanner at high resolution, with reduced bandwidth requirements. In one embodiment, groups of four scanned image pixel values, each one bit in length, are reduced to a single two-bit pixel value that determines a pixel value for a display image pixel; and selected displayed image pixel values are periodically varied between the original displayed image pixel value and an alternative pixel value to restore the perception of high resolution available in the scanned image.
