ABSTRACT:
An image processing apparatus and method capable of suppressing noise and improving the S/N ratio of a processing output signal when a color signal representing color image data is processed. The RGB.fwdarw.YUV converter is comprised of conversion units 201-1 . . . 201-k, adder 205, and rounding processing circuit 206 which are built in the image processing apparatus such as a color printer, each of the conversion units 10 201-1 . . . 201-k is provided with an adder 11 between the multiplier 10 and rounding processing unit 12 and corrects errors generated by the rounding processing circuit 206.
