PURPOSE:To simultaneously display the mutual correlation video between two different videos, by using a pair of TV camera capable of synchronizing horizontal scanning and by providing two systems of synchronizing pulse separation circuit which converts composite video signal into binary video signal plus video sigal pulse forming circuit. CONSTITUTION:TV cameras 14a, 14b, synchronizing separation circuits 10a, 10b and video signal pulse forming circuits 9a, 9b are provided and two sheets of input video 13a and 13b are picked up to obtain respective binary video signal. Two-way sweep oscillator 15 scans the cameras 14a, 14b horizontally at the same time so that the horizontal scanning directions become reverse directions to each other to obtain mutual correlation video in correlator 101. As the result, the videos displayed on a video receiver 16 are correlated video and the other video on the both sides of the center of the video plane. This input video is either one of two input videos previously described by switch 17 or pulse video which is converted into white and black binary. |
