Abstract

PURPOSE:To achieve easy collation with precision by displaying a registered picture and an objective picture on a video device alternately at desired intervals. CONSTITUTION:A retrieved picture on a microfilm is converted into a video signal through a TV camera3, and a picture of an object 4 is also converted into a video signal through a TV camera 5. The telecameras 3 and 5 output the video signals synchronizing with a synchronizing signal from a synchronizing signal generator 6, and a video switch 7 alternates those two video signals at intervals of a constant number of frames by using the vertical synchronizing signal of the synchronizing signal from the generator 6. The video output of the video switch 7 is displayed on a display device 8 while two pictures flicker by turns, so that the collation between both the pictures is achieved.
