Abstract
A color image is scanned in the matrix direction by the number of colors calculating unit and the number (A) of colors of different full color pixel values is counted. In this instance, each time the number (A) of colors is counted up, a pallet forming unit sequentially stores the full color pixel values as representative colors into entries and forms a subtractive color pallet. When the number (A) of colors exceeds the number (n) of entries of the subtractive color pallet, a transfer format discriminating unit counts the number (N) of transfer pixels up to the end of one-preceding row and compares a transfer data amount by a full color format with a transfer data amount by a pallet format in the number (N) of transfer pixels, thereby allowing the data transfer by the color format of a smaller one of the transfer data amounts to be executed by a data transfer unit.
