Claim One:
1. A method of providing color modification to a plurality of photographic film frames at a specified resolution, a video image of a photographic film frame at the specified resolution defining a predetermined number of pixels, said method comprising, for each given film frame, in combination: scanning each of a plurality of constituent frame portions of said film frame and thereby generating for each constituent frame portion a respective data stream of digital pixels representing a portion of a video image of the film frame at the specified resolution, the digital pixels in each data stream being only a portion of the predetermined number of digital pixels sufficient to produce a corresponding portion of the video image of the film frame at the specified resolution, whereby a combination of the data streams of digital pixels represents a complete video image of the film frame at the specified resolution, said digital pixels including data representative of at least hue, saturation and luminance of pixels in a respective constituent frame portion; selecting digital pixels in one or more of said data streams according to predetermined selection criteria, said predetermined selection criteria for a digital pixel comprising data indicative of one or more color characteristics selected from the group consisting of hue, saturation and luminance of said digital pixel; generating a selection signal indicating the selection of a digital pixel if said digital pixel meets said predetermined selection criteria; responsive to said selection signal, generating a respective modified digital pixel in response to each selected digital pixel according to predetermined modification parameters; in each data stream that contains at least one selected digital pixel, replacing each of said selected digital pixels with a respective modified digital pixel, thereby modifying said data stream; and subsequently assembling said constituent frame portions by combining said data streams to generate an output data stream representing a modified image of said film frame at the specified resolution.
