Abstract
In order to obtain the benefits of benefits of field and frame recursive noise reduction while reducing the detriments thereof, a circuit arrangement includes a motion compensated frame recursive noise reduction circuit and a motion compensated field recursive noise reduction circuit. The outputs of these two noise reduction circuits are then combined. The motion compensation vectors for the field and frame recursive noise reduction circuits are determined such that in the case of little or no detected motion, the system is biased toward frame recursive noise reduction to achieve the best resolution on still and slow moving scenes. While in the case of increased motion, the circuit reverts more to field recursive noise reduction to reduce smearing.
