Abstract

PURPOSE:To perform precise collation easily by displaying a retrieved registered picture and an objective picture alternately at desired intervals of time. CONSTITUTION:A registered picture retrieved on a microfilm is irradiated with light from an optical system to read its optical picture by the transmitted light. From an object 4, its reflected optical image is obtained through an optical system 5. The said two optical pictures are inputted to a changeover device 6 composed of a mirror, etc., which output the two optical pictures alternately at constant intervals of time. Those output optical pictures are displayed on a display screen 7 by turns, and consequently both pictures are collated with each other.
