A method and system for digitally performing a color transformation on digitized color film images. The digitized images may comprise frames of a digital video signal, with a red frame, a blue frame, and a green frame collectively corresponding to a digitized color image. The invention avoids aliasing error by employing a set of low pass filters, connected in parallel, to filter the digital input data prior to color correction. The output of each filter is processed digitally in a separate color correction circuit. Each color correction circuit implements a different polynomial term of a color transformation. The outputs of the color correction circuits are combined to generate a color corrected output data stream.
