Abstract: A projector system including a projector unit and a control device. The projector unit includes: a projector; a change mechanism that changes a projection direction; a plurality of optical systems having different optical properties; and a switch mechanism that selects one of the optical systems. The control device includes: a change unit that controls the change mechanism; and a switch unit that causes the switch mechanism to place one of the optical systems to be used for the projector in conjunction with the changing of the projection direction of the projector which is caused by the change unit.
