Abstract: A color transform enables color-image information to be recorded, displayed and otherwise processed with exacting control of color relative to a selected display. Apparatus implementing the transform enables a single-exposure photographic print of image information produced in pre-press equipment to predict with accuracy an ink-on-paper print of that information. Color-image information is transformed with a technique that produces output information for each output color component or other parameter at each point in response to up to all input parameters at that point. The technique includes scaling, normalizing and linearizing steps, and may include selecting a uniform color space for mapping the color response of the object (film) medium with the color response of the reference (print) medium. The output information may include approximate transform values and finalizing values.

Abstract: A signal processor for selective use with a conventional color television receiver for modifying the color image displayed on the screen of the receiver in order to enable a color photograph to be made by directly exposing a photosensitive material to the modified color image displayed on the screen of the receiver such that the photographic image is of an appearance substantially corresponding to the appearance of the image otherwise displayed on the screen of the receiver when the signal processor is not in use.
