Abstract

PURPOSE:To realize the multi-color separation of a color original with a low cost, by attaching a color original to an original drum of a scanner for a single color original, scanning the color original to obtain the picture information and supplying the optical signal to a photoelectric transducer via a desired color separating filter. CONSTITUTION:A color original 2 is attached to an original drum 1, and the light is irradiated to the original from a light source 6 in the case of a reflected original. Then the original is led into an inut head 5 to obtain an optical signal containing the picture information of the original 2. This optical signal is reflected by a mirror 4' and then mirror 8 to be supplied to a photoelectric transducer 12 after passing through an optional one of color separating filters 9, 10 and 11. The optical signal in the element 12 is conerted into an electric signal to bed led into an output head 17 after receiving an arithmetic process through an arithmetic circuit. For instance, when an original plate film for print is obtained, the electric signal is converted again into an optical signal to be exposed onto a photosensitive film attached to an output drum 18. When the separation is over for the 1st color, the 2nd and subsequent colors are separated in the same way.
