ABSTRACT:
An imaging system for applying separate color tonemaps comprises an optical scanning assembly configured to scan an object and produce image data having a first resolution that corresponds to a color characteristic. A memory device associated with the imaging system stores a look-up table that corresponds to a predetermined transfer function. An image data processor operatively associated with the memory device and the optical scanning assembly alters the resolution of the image data having the first resolution to produce image data having a second resolution, the second resolution being less than the first resolution, and also applies the image data having the second resolution to the look-up table to look up LowPoint image data having a third resolution, the third resolution being greater than the second resolution.
