Abstract

A low-cost, high-speed system for converting high-grayscale-resolution image data to a grayscale resolution optimized for a particular output device, such as an LED bar or ink-jet printhead. A static random-access memory accepts at its address port a full image datum. The most significant digits of the datum relate to a look-up table selected for optimum performance in a given situation. The least significant digits of the datum represent the actual image datum. When the full image datum is applied to the address port, the address location identical to the full image datum outputs an output value which has been pre-loaded into the memory.
