Abstract
PURPOSE:To emphasize the contour of a reproducing picture without deriving a synchronizing interference by transiting an emphasized band consisting of a high frequency emphasizing circuit to a low frequency side in a horizontal blanking period. CONSTITUTION:The titled device is provided with the high frequency emphasizing circuit 14 for emphasizing the high frequency component of a reproducing frequency modulating luminance signal and a synchronizing interference suppressing means 12 for transiting the emphasized band consisting of the high frequency emphasizing circuit 14 to the low frequency side during an operating period and suppressing the synchronizing interference due to a color noise parasitic during the horizontal blanking period at the time of a recording. Then, the high frequency component of the reproducing frequency modulating luminance signal is emphasized and the emphasized band consisting of the high frequency emphasizing circuit is transited to the low frequency side on the horizontal blanking period in which a high frequency emphasis appears as the adverse influence of the synchronizing interference. Thereby, an interference to a horizontal synchronizing signal is suppressed to emphasize the contour of the reproducing picture without generating the tension of the picture due to the synchronizing interference.
