A new method for noise reduction in image sequences is described which is based on a modified form of the well known first-order recursive temporal filter. The new features of the system are the improved separation of signal and noise and subsequently the reduction of noise in moving areas. This is accomplished without increasing the complexity of the whole system very much.
