a circuit and method for reducing artifacts in decoded color video and images are disclosed . the circuit includes a buffer for receiving an input pixel in a first color - space , and a detector for determining after transformation into a second color - space , if at least one component of the transformed pixel would fall outside a predetermined range . the determination may be made by comparing components of the input pixel , to corresponding ranges in the first color - space . upon determining that at least one component of the transformed pixel would be outside a corresponding predetermined bound in the second color - space , the detector causes the circuit to output a pixel in the first color - space , with at least one predetermined component . the output of the circuit may subsequently be converted to the second color - space by an external color - space converter and displayed onto a color display . the method reduces visible artifacts caused by clipping during color - space conversion .
