Abstract

PURPOSE:To input as much information as possible by selecting spectroscopin sensitivity characteristic in photoelectric conversion by a filter changing device and converting to characteristic corresponding to mode, and thereby controlling drop out color. CONSTITUTION:A paper 1 that has a picture to be inputted is illuminated by light sources 4a, 4b and the image is formed on a semiconductor sensor 7 by a lens 6 through a filter on the filter plate 5. Three kinds of band pass filter i.e. a #1 filter that transmits light of infra red domain, a #2 filter that transmits red and nearby color and a #3 filter that transmits blue and nearby color. The filters #1-#3 on the filter plate 5 are changed by a filter change driving circuit 8. Information is inputted as much as possible by selecting the mode of spectroscopic sensitivity characteristic in photoelectric conversion according to information regarding format of paper 1 programmed beforehand.
