COLOR REPRODUCING METHOD

There is provided a color image data processing method for reproducing a color image by use of micro color points of a plurality of colors. The processings for every region to obtain the areas of the color points are performed in parallel irrespective of which region in a plurality of regions on the chromaticity chart the color which should be reproduced belongs to, and among the respective processing results, the color points whose areas were determined to be positive values are used, thereby reproducing a color image.
