A noise reduction method for a video signal including a shooting step of shooting a subject by a CCD and outputting a video signal, a distance information acquisition step of calculating a shooting distance between the subject and the CCD, a specific distance information acquisition step of calculating a specific distance which is a shooting distance between one subject of the subject and the CCD on the basis of focus information of the one subject, a relative distance calculation step of calculating a relative distance corresponding to the video signal on the basis of the shooting distance and the specific distance, and a noise reduction step, including a smoothing step of performing smoothing processing on the video signal on the basis of the relative distance, of performing noise reduction processing on the video signal on the basis of the relative distance.
