An object is to enable a suitable image conforming to the movement of an imaging target to be captured. A motion detection device provided on an imaging target side (person or movement object) detects the motion of the imaging target, which is transmitted as motion information. An imaging apparatus receives the motion information detected by the motion detection device, predicts the motion of the imaging target based on the motion information, changes imaging settings based on the predicted motion of the imaging target and controls imaging function based on the imaging settings.
