A hardware implementation of a digitized image corrector is disclosed that converts a colorimetric representation of an original image into a new representation based upon the colors of the original and target images, as well as user supplied artistic parameters. The digitized image corrector receives digitized Red, Green and Blue input signals that comprise a colorimetric representation of an original film scene, and generates digitized Red, Green, and Blue output signals according to the specifications of SMPTE 240 M. The digitized image corrector is comprised of four identical hardware correction modules, which are coupled to receive correction parameters from an external source. Each module has a bypass switch for entering a bypass mode, which is used for reconfiguration of the module's correction parameters without affecting the output image. Each correction module receives digitized input signals and generates digitized output signals by transforming the digitized input signals according to a set of predetermined correction parameters and a transfer function defined by a matrix of functions.
