A projector system of this invention includes a camera and a projector. The projector includes a projection image forming unit which forms an image to be projected to a projection surface and a projecting lens. When photographic information in photographing a projection image and distance information to the projection surface are input, a display control unit controls the focal length of the projecting lens in accordance with the photographic information and switches the size of the image formed by the projection image forming unit at the variable control limit of the focal length.
