ABSTRACT:
The present invention is a method and apparatus for logic based resolution conversion and enhancement of digital images. The invention employs a selectively controllable architecture wherein a plurality of input resolutions can be converted to a common output resolution. The system has particular use in highlight color systems, wherein the highlight color data may be processed separately for each color plane, using the present invention, and then recombined to produce enhanced highlight color output. Moreover, the hardware preferably employs an interlocked area mapping technique to produce the resolution converted bit planes of digital image data.
