Abstract
The colorimetrically exact reproduction of color in simultaneous television is now possible, through the congruence of the camera spectral sensitivities to definite characteristics specified by colorimetry and through the combination of the camera signals in both positive and negative amounts by suitable circuits and amplifiers. The negative sensitivities of the photo- pickups formerly required for certain spectral wavelength intervals are obviated by these signal-mixing circuits, and simultaneous color television, both as to color range and accuracy of reproduction, is capable of the finest color reproduction available anywhere. The mixing circuits perform a function resembling that known in color photography as masking, but whereas the latter is always approximate and often a hit-or-miss procedure, the television system can approach perfection without undue complication. The basic concepts and relations of trichromatic colorimetry are here developed. Many of these relationships are of immediate importance in color reproduction and are stated explicitly, with the aid of a concise notation. In addition, certain rather philosophic aspects of television as a means for the communication of sense perception are discussed and a plea is made for the extension and compilation for television purposes of knowledge about the properties of the eye.
