ABSTRACT:
A color facsimile transmission apparatus wherein a beam of white light is dispersed into component colors by a prism. The color dispersed bands of illumination are focused to irradiate a portion of a moving document. The reflected, colored light from the document is focused on the surface of three charge coupled devices (CCDs) so that the red illuminating band irradiates a first CCD and the green and blue bands respectively irradiate the second and third CCDs. The movement of the document causes each line of the document to scroll through the illuminating band over each of the CCDs. The CCDs are operated in the time delay and integration mode to generate charge packets corresponding to the picture elements of the red, green and blue component line images of each line of the document.
