Abstract:
     ABSTRACT :A noise reduction system is comprising a first ckt using to get perpendicular correlative signal-components from the duplicated vidio signals out of image recorder when these duplications are making; a subtraction ckt being operated to minus th output siggnals of the first ckt from the duplicated vidio signals to get the new dupliated vidio signal-components, a chopper ckt being only to pass the output signals of the first subtraction ckt whose level are higher than that of the chopper. The adder adds together the output signals of the first ckt with that of the chopper. The level strengthened ckt raises the lower and medium level components of the recorded vidio signals whose images are recorded on the recording medium without the perpendicular correlation components at the time of recording.
