PURPOSE:To attain low cost of device constitution by providing a correction circuit to a recording system and recording a video signal through the correction circuit to a recording medium after the signal is modulated. CONSTITUTION:A color video signal incoming to an input terminal 1 is fed to a low pass filter 2 and a separated luminance signal is fed to the correction circuit 4 provided newly. After the level of a high frequency component of a small amplitude is strengthened, the result is fed to a luminance signal recording processing circuit 5 and after it is converted into a signal to be frequency-modulated, the result is fed to a mixing circuit 6 and recorded on a magnetic tape 10. Thus, the deterioration of the reproduced video signal component with the small amplitude and high frequency is eliminated nearly at the reproducing system and the deterioration of the resolution of a small amplitude video signal is prevented. |
