Provided is an endoscope device capable of performing appropriate NR processing in both of a white illumination light imaging system and a narrow band imaging system and a noise reduction processing method. An endoscope device 1 is provided with a noise reducing unit which selects a pixel of interest based on used filter information determined according to light emitted by a light source unit 3 and a characteristic of each filter forming a color filter 202a and detects motion between images captured at different times by using an electric signal output by the pixel of interest, thereby reducing a noise component included in the image signal.
