Patent number: 7720365Abstract: A photographic device, includes a shake detector, a shake mitigator, a first commander, and a shake controller. The shake detector detects a device shake, that is, a shaking of the photographic device. The shake mitigator mitigates the effects of the device shake to reduce an image shake that is a shake of a photographed subject image. The first commander commands the photographic device to photograph the subject image. The shake controller controls the shake mitigator so that the shake mitigator refrains from mitigating the effects of the device shake from the point when the first commander commands the photographic device to photograph the subject image, until the point when photographing the subject image commences.Type: GrantFiled: March 5, 2007Date of Patent: May 18, 2010Assignee: Hoya CorporationInventors: Kosei Kosako, Masahiro Inazuka, Takuma Sato, Shinichi Kakiuchi, Shinya Suzuka

Patent number: 6160962Abstract: A lens barrier apparatus includes a lens barrier having opened and closed positions, The lens barrier is positioned on the front face of a lens barrel and protects a camera lens. A motor which drives the opening/closing of the lens barrier and an encoder outputs a predetermined signal together with the rotation of the motor. A drive control when a battery is loaded in the camera, drives the motor in a direction in which the lens barrier is closed and, when the predetermined signal is not output from the encoder during the driving process, drives the motor in a direction in which the lens barrier is opened and then drives the motor in the direction in which the lens barrier is closed again.Type: GrantFiled: July 21, 1998Date of Patent: December 12, 2000Assignee: Asahi Kogaku Kogyo KaishaInventors: Hiroshi Nomura, Yasushi Tabata, Norio Numako, Yoshinari Tanimura, Takuma Sato, Masaaki Kishimoto

Patent number: 6036377Abstract: A camera with lens barrier apparatus in which the lens barrier apparatus is driven by a motor that is also used to drive another mechanical element in the camera. The motor is switched between the lens barrier apparatus and the mechanical element by the movement of a lens barrel. In this arrangement, the driving of the lens barrier apparatus and the mechanical element are controlled in accordance with the output of a single sensor, for example an encoder.The driving of the lens barrier apparatus is controlled such that the barrier will not close unless the lens barrel is at the housed position and such that if the lens barrier does not open, the lens barrel will not move. The driving is further controlled such that if the lens barrier apparatus does not move to its intended state, the drive is reversed prior to again attempting to drive to the intended state.Type: GrantFiled: July 21, 1998Date of Patent: March 14, 2000Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hiroshi Nomura, Yasushi Tabata, Norio Numako, Yoshinari Tanimura, Takuma Sato, Masaaki Kishimoto

Patent number: 5999748Abstract: A zoom camera includes a lens that is movable from a housed position to an arbitrary position in a photographing enabling range. A lens driver drives the lens, a lens barrier moves between opened and closed positions, and lens barrier closing mechanism moves the lens barrier between an opened position and the closed position. A detector detects that the lens has moved from a position within the photography enabling range to the housed position and controller prevents the lens barrier closing mechanism from moving the lens barrier to the closed position unless the lens is at the housed position.Type: GrantFiled: July 21, 1998Date of Patent: December 7, 1999Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hiroshi Nomura, Yasushi Tabata, Norio Numako, Yoshinari Tanimura, Takuma Sato, Masaaki Kishimoto
