A color correction system contains a plurality of color channels which each contain a dichroic mirror and an electro-optical modulator. An unpolarized light source shining through a color transparency serves as the input to each channel, and each color is individually controlled by the electro-optical modulator in its respective channel. The colors of each channel are then recombined after correction. In another embodiment of the invention, each channel further includes mono-color film storage means as black and white film storage means to store the color image of the particular channel on such an inexpensive film for subsequent reconstruction as a picture of different color than the film color. In a further embodiment, a plurality of separate colors of the same color image are stored on spaced regions of a given frame area of a mono-color negative, especially of a black and white negative, along with verbal information which is to be projected with the corresponding color image.
A photographic film for storage of an image and of additional information, comprising a film negative having at least two separated, non-overlapping areas, one of said areas containing said additional information and the other of said areas containing the information constituting said image;
An information storage and retrieval system, comprising:
In combination:
The method of storing a two-dimensional color image and additional information, comprising the steps of:
