Patent ID: 8351076

Claim:
An imaging device comprising: an interface that receives image data including color data in a first color space; a controller that accesses the image data received by the interface, the controller transforming the color data in the first color space to a second color space; and, a memory unit, the memory unit storing a table that is used by the controller to transform the color data from the first color space to the second color space, the table comprising: a plurality of smoothed entries, each smoothed entry being a color dimensional value for a color dimension within the second color space, the smoothed entries being indexed by a color dimensional value for each color dimension in the first color space; wherein the plurality of smoothed entries in the table are equivalent to values that can be obtained by replacing unsmoothed entries for the table with smoothed entries, where a first unsmoothed entry is replaced with a first smoothed entry, the first smoothed entry being a weighted mean of a subset of unsmoothed entries, the subset of unsmoothed entries including the first unsmoothed entry and other unsmoothed entries that are indexed by the same color dimensional values as the first unsmoothed entry for all but a first color dimension in the first color space.
