A computerized video imaging system is provided which includes a target mount for supporting a target photographic transparency. A lamphouse is positioned to pass light through the transparency and includes light sources for a set of primary colors. An image sensor is positioned to receive light passing from the lamphouse through the transparency and generates video signals representing hue and intensity of the light. Image storage means are provided for storing color reference representations of the reference transparency. A color video monitor receives signals related to the reference representations and the target video signals. A computer interfaces with the light source and the image storage to calculate photographic color correction values for the target transparency.

A computerized video imaging system comprising: (a) target mounting means for supporting a color photographic production target; (b) lamphouse means positioned to illuminate said target and including light sources respectively of a set of primary colors, the intensities of light from said light sources being controllable individually and collectively in measurable amounts; (c) an image sensor positioned to receive light from said lamphouse means as altered by interaction with said target and generating over a time cycle a set of color component production video signals which in combination represent the hue and intensity of light as altered by interaction with spatial regions of said target; (d) image storage means storing color reference representations of a substantial area of a reference target, said reference representations being related to a reference balance of intensities of said light sources; (e) color video monitor means operatively connected to said image sensor means and said image storage means, receiving signals related to said reference representations and said production video signals, reproducing at least a portion of a production image representative of said production target as illuminated by said lamphouse means and at least a portion of a reference image representative of said reference transparency as illuminated by said lamphouse means with said light sources set to said reference balance; (f) light source adjustment means for adjusting the intensities of light from said light sources, said adjustment means being adjusted until the color balance of said production image assumes a production balance wherein the color balance of said production image as viewed on said monitor means appears to match the color balance of said reference image as viewed on said monitor means; and (g) computer means interfaced to said adjustment means and said image storage means and operative to calculate photographic color correction values for said production target which are representations respectively of the differences between the intensities of light from said light sources for said production balance and the intensities of light from said light sources for said reference balance.
