Abstract
Color conversion systems and methods using an interpolation table that minimizes interpolation color value generation times and reduces memory storage of interpolation tables. A first color conversion method and system reduces interpolation table generation times by generating interpolation color values on an 'as needed' basis while performing color conversions. A second color conversion method minimizes interpolation table memory storage by dividing the interpolation table into segments, allocating primary memory storage to store only a given number of segments and establishing a segment status bit array to indicate whether a given segment is currently stored in primary memory. A third system and method combines both the first and second methods so that both interpolation table generation times and table memory storage is reduced.
