Patent number: 8896710Abstract: A zoom lens barrel capable, even if it has an image shake correction mechanism and a diaphragm mechanism, of decreasing a distance between lens groups of a photographing optical system of the lens barrel, whereby the lens barrel size can be reduced and the magnification can be increased, and capable of preventing a collision between diaphragm blades of the diaphragm mechanism and the lens groups from occurring when vibration, impact, or the like is applied to the lens barrel. When apart of an image shake correction lens intrudes into an aperture of diaphragm blades, a restricted portion of a lens holding member and a restricting portion of a diaphragm restrict a maximum movement of the lens holding member in a direction perpendicular to the optical axis, thereby restricting a maximum amount of movement of the image shake correction lens in the direction perpendicular to the optical axis.Type: GrantFiled: August 27, 2012Date of Patent: November 25, 2014Assignee: Canon Kabushiki KaishaInventor: Tomoyuki Kudoh

Publication number: 20140334809Abstract: A vertical axis shock and vibration isolator for a camera has first and second plates connected by linkages which allow the plates to move towards and away from each other, while keeping the plates parallel to each other. The second plate is suspended from the first plate on dampener assemblies having a spring and a fluid dampener. The isolator may be used in an under slung or an over slung position, without changing its isolation characteristics. When set up in an over slung position, the dampener assemblies may be inverted separately from the isolator so that the springs remain loaded in compression.Type: ApplicationFiled: May 8, 2013Publication date: November 13, 2014Inventor: Leonard T. Chapman

Patent number: 8873942Abstract: The image capturing apparatus detects a rotational shake and translational shake produced by an apparatus by a rotational velocity meter and an acceleration meter. A rotational shake compensation coefficient calculation unit calculates a compensation (correction) coefficient in relation to rotational shake. A translational shake compensation coefficient calculation unit calculates a compensation (correction) coefficient in relation to translational shake. When calculating the compensation amount in relation to rotational shake and translational shake using the respective compensation (correction) coefficients, the camera CPU acquires information indicating a degree of focus of the imaging optical system, and suppresses variation in the compensation amount by reducing the compensation (correction) coefficient when the degree of focus is low.Type: GrantFiled: June 7, 2012Date of Patent: October 28, 2014Assignee: Canon Kabushiki KaishaInventor: Nobushige Wakamatsu

Patent number: 8861947Abstract: A active stabilization system and a method for correcting a pointing direction of a camera to compensate for translational movements of the camera are described. The system actively stabilizes a pointing direction of the camera in accordance with a commanded pointing angle. A distance from the camera to a filming target is determined and one or more translational measurements associated with a translational movement of the camera are derived. A correction update is calculated as a function of at least the distance and the one or more translational measurements. The commanded pointing angle of the camera is adjusted based on the correction update to retain the filming target within a field of view of the camera.Type: GrantFiled: March 14, 2014Date of Patent: October 14, 2014Assignee: Freefly Systems, Inc.Inventors: Steve Webb, John Ellison, Tabb Firchau
