ABSTRACT:
A color noise killing circuit for video tape duplicating apparatus which is capable of eliminating the color noise during a fine copy mode comprises mode setting circuit, color signal detecting circuit, selecting circuit and transmission, controlling circuit so that the color noise killing circuit detects via color signal detecting circuit a color signal of the play back system during the fine copy mode and thereby the transmission controlling circuit controls the selecting circuit to selectively supply signals corresponding to the respective modes to the recorder system. Consequently, by supplying the recorder with only luminance signals when black and white image signals are reproduced during the fine copy mode, the circuit achieves an improvement of picture quality duplicated.
