<P>PROBLEM TO BE SOLVED: To provide an image processing device in which the man hour of subtractive color processing is reduced. <P>SOLUTION: An image processing device comprises a classification unit which creates a lookup table by dividing a color palette where RGB data is made to correspond with index into a plurality of groups based on the relation of the R value, G value and B value of the RGB data, a storage unit which stores the lookup table, and a conversion unit which determines to which of the plurality of groups pixel data having the RGB data corresponds based on the relation of the R value, G value and B value of the pixel data, searches RGB data similar to the RGB data of the pixel data in the determined group, and outputs the index corresponding to the searched RGB data as the pixel data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
