  • Image display using irregularly placed curving structures
    Patent number: 5808622
    Abstract: A method and apparatus for digital halftoning places curving structure centers at random locations within a halftone cell. Pixel illumination ordering is determined based on displacement from a pixel to a nearest CSC along a curving structure. Curving structures including spirals with varying numbers of arms, varying angles of departure, varying orientations, and varying other parameters are used to achieve visual aesthetics as desired.
    Type: Grant

    Date of Patent: September 15, 1998
    Inventor: Daniel Hall
  • Image display using evenly distributed intensity clusters
    Patent number: 5784049
    Abstract: A method and apparatus for digital halftoning provides evenly distributed intensity clusters within a halftone cell. Pixel illumination ordering is determined based on adjacency from a candidate pixel to other pixels already placed in the order of illumination. Separate head and tail intensity arrays are used so that pixel ordering proceeds from both the first and last illuminated pixels toward pixels in the center of the illumination order.
