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.
