Abstract
PURPOSE: To obtain a high-contrast composite image by recording the embedded video signal and at the same time recording previously the ideal sampling signal.
CONSTITUTION: The device consists of the following units: color VTR1; filter circuit 2; detection circuit 3; LPF4; synchronous signal generation circuit 5 which delivers the synchronous signal to secure the synchronism between the embedding signal and the embedded video signal supplied; counter 6 which supplies the horizontal and vertical synchronous signals for counting and clearing respectively; delay circuit 7 which delays the output signal of counter 6; FF circuit 8 which supplies the output of filter 4 and then the output of circuit 7 as the clock signal; pattern sampling circuit 9; gate circuit 10 which supplies the output of circuit 9 and then the output signal of circuit 9 as the control signal; pattern memory 11 which supplies the output of circuit 10 and then records the sampling signals equivalent to one frame; sampling signal generation circuit 12; color pickup unit 13; switch circuit 14; color picture receiver 15 and others. Thus a good composite video can be obtained at receiver 15 through switching by circuit 14.
