PURPOSE:To decrease the number of the circuit correcting temperature characteristics of the level of the delay video signal by using a charge coupled element as a 1H delay element. CONSTITUTION:A reproduction video signal consisting of a reproduction luminance signal and reproduction color signal formed with an adder 15 is supplied to a fixed terminal 16 of a switch 16. The reproduction video signal is supplied through a movable terminal 18 to an output terminal 30 when the dropout will not occur, and is given to a charge coupled element 22. Next, the delay video signal delayed to 1H with the charge coupled element 22 is supplied to a fixed terminal 17. When the dropout occurs, the delay video signal supplied to the fixed terminal 17 is outputted through the movable terminal 18 to the output terminal 30 and is corrected. As such, since the signals are formed, the temperature characteristics of the level of the delay video signal are influenced with the charge coupled element only. Consequently, the number of the circuit correcting the characteristics can be decreased. |
