IMAGE DUBBING CIRCUIT

PROBLEM TO BE SOLVED: To mutually perform image dubbing by a single image processing circuit. SOLUTION: Signals from a line input terminals 1Y, 1C are supplied to one contactor a of a first and a second input selecting means 2Y, 2C and 3Y, 3C, respectively. The signals selected by the first input selecting means 2Y, 2C are supplied to a first recording reproducing device 4 and the signals selected by the second input selecting means 3Y, 3C are supplied to a second recording reproducing device 5. Furthermore, the reproducing signal from the first recording reproducing device 4 is supplied to one contactor (a) of an output selecting means 6Y, 6C, respectively and the reproducing signal from the second recording reproducing device 5 is supplied to the other contact (b), respectively. And the signals selected by the output selecting means 6Y, 6C are supplied to an image processing circuit 7. Furthermore, an output signal from the image processing circuit 7 is fetched to the line input terminals 10Y, 10C and simultaneously supplied to the other contactor b of respective input selecting means 2Y, 2C and 3Y, 3C.
