Abstract

PURPOSE:To emphasize a high frequency part large in the change of a brightness visually outstanding on the reproduced picture and to obtain a reproduced signal excellent in a resolution, by relatively raising the level of the high frequency part of a luminance signal in a frequency correcting circuit. CONSTITUTION:In the reproducing device for a video signal for individually processing the luminance signal and a chrominance signal such as a demodulation, mixing both the signals and outputting, signal processings with the operation of the frequency such as the demodulation, a deemphasis and a noise reduction are executed, thereafter, the frequency correcting circuit 9 for emphasizing a high frequency band easily visually outstanding of the reproduced picture is interposed in the processing systems 4, 6, 7, 8 of the luminance signal before mixing with the chrominance signal. Thereby, since the high frequency level of the luminance signal of a base band is emphasized by the frequency correcting circuit 9, a part corresponding to the part high in the frequency, namely, the picture of the part large in the change of the brightness is clearly reproduced.
