Patent number: 6339510Abstract: A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.Type: GrantFiled: October 11, 1994Date of Patent: January 15, 2002Assignee: Minolta Co., Ltd.Inventors: Nobuyuki Taniguchi, Masaaki Nakai, Takanobu Omaki, Tokuji Ishida, Hisayuki Masumoto, Hisashi Tokumaru, Tsuneyo Metabi
