Abstract

An optical scanner generates facsimile signals. Each pixel of a scanned image is observed by separate fiber optic elements at different times. Each fiber optic collector directs the light through a color filter and the thus filtered light is detected. Separate color signals are then correlated to associate respective colors with each pixel of the scanned image.
