ABSTRACT:
An image enhancement method in which low-resolution bitmapped images may be enhanced and converted into gray images for printing on high-addressability printing and display systems. The method uses template matching to determine a rendering goal, and converts the bitmap pixel into a numerical, multiple-bit-per-pixel sampled value that is independent of the system it may ultimately be printed on. Unlike previous template matching methods which determined an enhanced pixel pattern output which was sent directly to the photoreceptor of a specific printer, the sampled data value of the present invention will require processing by the printer for its own particular characteristics before being sent to the photoreceptor. The sample data value may be sent directly to a printer imaging processor or stored via a network.
