Abstract: A synchronization controller performs control so that operator motion data is transmitted to a robot when a synchronization switch is set to ON which allows synchronization of a rotational motion of an operator with a rotational motion of the robot. An image correction unit, when there is a difference between a first rotation angle of the operator and a second rotation angle of the robot, corrects a cutout range of an image so as to be equal to a range corresponding to the first rotation angle. The synchronization controller performs control so that the operator motion data is not transmitted to the robot when the synchronization switch is set to OFF which does not allow synchronization of a rotational motion of the operator with a rotational motion. The image correction unit corrects the cutout range so as to be equal to a range corresponding to the first rotation angle.

Abstract: When a controller controls a driver so as to move a moving unit in accordance with a user's movement, the controller controls a video signal processor such that frame videos of a video signal transmitted to an image display device have a first display mode. When the controller controls the driver so as to move the moving unit regardless of the user's movement, the controller controls the video signal processor such that frame videos of a video signal transmitted to the image display device have a second display mode.
