To provide: a moving image noise reduction processing apparatus for obtaining a high-quality image signal by controlling noise reduction processing in accordance with a feature pixel; a moving image noise reduction processing program; and a moving image noise reduction processing method.

Time-sequential image signals obtained by an acquisition section 2 are subjected to noise reduction processing in a space direction and a time direction by a space noise reduction section 106 and a time noise reduction section 107 and input to a noise reduction control section 6, and a feature pixel is detected by a feature pixel detection section 5. The noise reduction control section 6 controls noise reduction by controlling mixture of both pixel values of both noise-reduced image signals in accordance with the presence/no presence of the feature pixel.
