ABSTRACT:
A method of forming an electric signal wherein the signal level corresponding to the selected color in the original indicates the maximum or minimum value. The original is exposed to the light and the reflected light is introduced into a photoelectric converting means through two different paths, each of which has a filter corresponding to a different selected color. These two signals are multiplied by a predetermined ratio, and are combined to obtain the final image signal.
