  • Technique for optimizing grayscale character displays
    Patent number: 4945351
    Abstract: Appropriate luminance linearization values are determined for improving sub-pixel positioning of image edges in grayscale displays. Individual display devices may be calibrated by and end-user, or factory luminance linearization settings may be determined. Grayscale characters may be optimized for specific display devices.

  • Grayscale character generator and method
    Patent number: 4851825
    Abstract: A method and system for efficiently generating grayscale character fonts from bi-level master character fonts decomposed into rectangles. For each filter array to be used for converting master character fonts into grayscale characters there is generated at least one summed area filter array. Each element in each summed area filter array represents the sum of the filter array elements in a corresponding subarray of the filter array.
