To provide a moving image noise canceling device accurately canceling noise even in a moving image signal of a low signal-to-noise ratio.
A moving image noise canceling device 1 comprises: a temporal/spatial wavelet decomposing means 10 for performing wavelet decomposition on a moving image signal in a temporal direction and further performing wavelet decomposition thereon in a spatial direction; a temporal/spatial wavelet shrinkage means 30 for performing wavelet shrinkage by setting different thresholds to frequency components on which wavelet decomposition has been performed in the temporal direction and the spatial direction; and a temporal/spatial wavelet reconfiguring means 40 for performing wavelet reconfiguration on the wavelet-shrunk frequency component in the spatial direction and further performing wavelet reconfiguration thereon in the temporal direction to generate a moving image signal.
