IMAGE PICUP PROCESSING SYSTEM

PURPOSE:To set the image pickup of conference attendants obtained by two cameras into a screen with no oscillation of the cameras non any change of the vertical deflecting current, by shifting the phase of a vertical driving signal of camera to the phase of a vertical synchronous signal by a desired degree. CONSTITUTION:Plural conference attendants are picked up by two cameras and displayed on a screen. In this case, horizontal and vertical synchronous pulses H and V and supplied to counters 6 and 8 plus an odd-even field deciding circuit 7. The pulses H are counted by the counter 6 and at the start point of the pulse V, and the 200H and 59H shift vertical driving signals are produced at the start point. Then the shift vertical signals of even and odd fields are produced from the control pulse decided at the circuit 7 and through AND circuits 9-12 plus 1//2 delaying circuits 13 and 14. Vertical driving signals VD1 and VD2 of camera are delivered from OR circuits 15 and 16. At the same time, the pulses of 20H, 141H and 261H are delivered by a counter and at the start point of the pulse V. Then, the pulses are delivered from gate pulse generating circuits 17 and 18. Thus the pictures can be easily put into a screen.
