Method of color separation in color photographing or printing and trichromatic separation filter

摘要

The color separating method for color photographing or printing is such that in case a color photosensitive material is used and the color separation is carried out by the color separating method, three kinds of filters consisting of three primary colors are caused to be sequentially or selectively disposed upon or removed from the optical axis of a light condensing unit in a lens group consisting of a large number of lenses of an optical system, and white light conducted from one end of the lens group is made to project the separated color component at the other end. The three filters are disposed upon a rotary filter support board which is selectively rotated by a control motor and a controller for the control motor which receives input control signals from a suitable source and outputs control signals to the control motor.
