Abstract
PURPOSE:To realize a still video player used in common for color/white-black color capable of reproducing white/black signal with high resolution without revising the pass band of a delay element by supplying directly a luminance signal demodulated by a demodulation means to an amplifier means at a black/ white picture. CONSTITUTION:A switch 18 is provided between a mixing circuit 17 and an amplifier circuit 19 and a switch 34 is arranged in parallel with a high pass filter 7, and in case of black/white signal reproduction, a mode changeover circuit 32 turns off a switch 33 to cut off color noise and to turn on the switch 34 thereby throwing the switch 18 to the position (c). As a result, a signal amplified by a head amplifier is fed directly to the FM demodulation circuit 8, and the luminance signal subject to FM demodulation and de-emphasis is fed directly to the amplifier circuit 19. Since the high frequency component of the luminance signal at reproduction is not deteriorated, the resolution of the picture is not lowered. Thus, even when a high definition white/black picture is recorded, a sharp reproduced picture without picture quality deterioration is obtained.
