ABSTRACT:
A device comprises a look-up table translating unit, a region dividing unit and a reduced image generating unit to reduce the size of a color image using look-up tables and a reference look-up table. Each of the look-up and reference look-up tables has as many entries as there are the pixel values. The look-up table translating unit creates an entry check table. The entry check table is for translating the table entries of the look-up table into the those of the reference look-up table. The region dividing unit divides the original color image into a plurality of regions. The reduced image generating unit accesses the entry check table and the reference look-up table to selectively determine a representative pixel of the region based on the RGB values thereof to generate the reduced color images.
