Patent number: 7397955Abstract: Whether a portrait photography mode has been set is determined. A first threshold value is set when the portrait photography mode has been set and a second threshold value that is smaller than the first threshold value is set when the portrait photography mode has not been set. A cross-correlation coefficient between the image of the subject and a template image is calculated. The calculated coefficient and the set threshold value are compared and the position of the image of a face is detected in the image of the subject. When the portrait photography mode has been set, it can be construed that the subject contains a person and therefore the position of the face image can be detected comparatively accurately by increasing the threshold value.Type: GrantFiled: May 10, 2004Date of Patent: July 8, 2008Assignee: Fujifilm CorporationInventor: Masahiko Sugimoto

Patent number: 6321038Abstract: A camera, lens positioning mechanism and method use a lens holding member to hold a lens therein for receiving optical information that may be captured on film or digitally. The lens holding member interfaces with a ring-shaped barrel member, geared ring or the like, that when turned in one direction by a motor forces the lens holding member out, or back, depending on a slope of a cam placed on the barrel member, slot in the barrel member or the like. When driven in the single direction, the cam member on the ring barrel member, forces the lens holding member in a predetermined direction. A biasing member connected to the ring provides an opposing force that when used during a focusing operation pulls the lens holding member and cam member back to a home position without the need of a driving force from the motor. A clutch mechanism engages and disengages the driving force of the motor on the geared ring depending on whether a focusing operation, lens storage operation, or zooming operation is performed.Type: GrantFiled: April 30, 1999Date of Patent: November 20, 2001Assignee: Ricoh Company, Ltd.Inventor: Tomoyuki Kudoh

An output unit mechanically engages the film transport. The output unit defines an axis of rotation. An outer winder is coaxial with the output unit. The outer winder is rotatable about the axis in first and second directions of rotation relative to the body. An inner winder is nested in the outer winder. The inner winder is coaxial with the output unit. The inner winder is rotatable about the axis in the first and second directions of rotation independent of the outer winder. Outer and inner clutches are disposed between respective winders and the output unit. The outer clutch couples the outer winder to the output unit during rotation of the outer winder relative to the body in the first direction of rotation.Type: GrantFiled: July 21, 1997Date of Patent: November 24, 1998Assignee: Eastman Kodak CompanyInventor: Patricia L.

Patent number: 5835805Abstract: A film transporting device transports photographic film by driving a spool of a cartridge and a takeup spool which takes up the photographic film supplied from the cartridge by means of a single motor which is rotatable forward and backward. Unidirectional rotational driving force is transmitted from the motor to the spool and the takeup spool via one planet gear mechanism, and the photographic film is supplied from the cartridge, and then the takeup spool takes up the photographic film. The rotational driving force from the motor in the other direction is transmitted to the spool via the planet gear mechanism, and the photographic film is rewound into the cartridge. When the takeup spool takes up the photographic film, a one way clutch can absorb a difference of the transport speed between the takeup spool and the spool of the cartridge.Type: GrantFiled: April 4, 1997Date of Patent: November 10, 1998Assignees: Fuji Photo Film Co., Ltd., Fuji Photo Optical Co., Ltd.Inventors: Toshihiko Izaki, Yasuhiko Tanaka

Patent number: 5781810Abstract: A camera that effectively uses only two film supply motors. The operation of supplying film from a cartridge is performed by driving a first motor in a first direction. The operation preparatory to magnetic recording on the film is performed by driving the first motor in a second direction different from the first direction. Further, the operation of winding the film on the camera side is performed by driving a second motor in a third direction. The operation of rewinding the film into the cartridge is performed by driving the second motor in a fourth direction different from the third direction. Alternatively, the second motor fourth direction can be used to perform the operation preparatory to magnetic recording, and the first motor second direction can be used to perform the film rewinding. The present invention applies to normal or prewinding cameras.Type: GrantFiled: June 18, 1997Date of Patent: July 14, 1998Assignee: Nikon CorporationInventor: Tsutomu Wakabayashi

Patent number: 5765067Abstract: A film rewinder for rewinding film from a film cartridge to an intermediate cartridge. Its driving unit for rotating the film cartridge spool is also used to drive a tool for separating the film trailing end from the film cartridge spool. The film cartridge has a tool guide, so that the entire device is sufficiently compact. The film rewinder has a film cartridge receptacle and a winding unit for winding the film fed from the film cartridge into the intermediate cartridge. A film guide is provided between the receptacle and the winding unit. The spools of the two cartridges are driven by separate motors independently of each other. The tool is an arcuate member adapted to be pivoted in a circular path by the motor for the film cartridge. In order to minimize the length of the film guide and thus to minimize the size of the entire film rewinder, the film guide is provided with a release guide.Type: GrantFiled: October 23, 1996Date of Patent: June 9, 1998Assignee: Noritsu Koki Co., Ltd.Inventor: Takuji Yamaguchi

Patent number: 5729779Abstract: A film transport system to be used in cameras for the Advanced Photo System cartridge film, which have one motor for feeding the film out of the cartridge and for taking up the film on the take-up spool, one sun gear with two planet gears in the film driving gear train to switch the direction of film drive between feed and take-up on the one hand and rewind on the other hand. An arc shaped slot receives the axle of the film advance (feed and take-up) planet gear to accommodate differences of speed between feeding and taking up of the film. This avoids the need for a one way clutch and a separate rewind gear train.Type: GrantFiled: July 16, 1996Date of Patent: March 17, 1998Assignee: Arc Design Room Ltd.Inventor: Shigeru Oshima

Patent number: 5713530Abstract: A film winder which can stop the rotation of a film winding spool at a constant position. The film winder has a drive pin for rotating the spool in a film cartridge. The drive pin carries a gear having a boss formed with a flat engaging portion on its outer periphery. A stopper member is provided which can pivot and engage the engaging portion. The spool is rotated by the drive pin to wind film around the spool. After a film detection sensor provided near the opening of the cartridge has detected the passage of the film tip, the stopper member is pivoted toward the boss and engages the engaging portion of the boss, thus stopping the drive pin. The spool can thus be stopped at a constant position.Type: GrantFiled: February 19, 1997Date of Patent: February 3, 1998Assignee: Noritsu Koki Co., Ltd.Inventor: Hiroaki Tamura

Patent number: 5682565Abstract: A feeding tooth of a one-tooth sprocket retracts from a film so that the film can be prevented from being damaged by the feeding tooth of the one-tooth sprocket when the film is rewound. When a motor rotates in a film winding direction, a rewinding fork becomes free and a spool and the one-tooth sprocket rotates in a winding direction. As a result, the feeding tooth of the one-tooth sprocket engages with a perforation of the film to feed the end of the film up to the spool. On the other hand, when the motor rotates in the film rewinding direction, the one-tooth sprocket becomes free and the spool and the rewinding fork rotate in the rewinding direction. As a result, the film is wound around a rotation axis of a patrone. In this case, the feeding tooth of the one-tooth sprocket retracts from the film.Type: GrantFiled: March 8, 1995Date of Patent: October 28, 1997Assignee: Fuji Photo Optical Co., Ltd.Inventors: Takashi Kamoda, Takashi Mashiko
