Abstract: An image stabilizer includes a first optical corrector moving along a direction different from an optical axis to correct an image shake, a second optical corrector moving along a direction different from the optical axis to correct an image shake, a controller moving at least one of the first and second optical correctors to correct an image shake, and a first position detector detecting information about a movement position of the first optical corrector. The controller performs image shake correction of the first optical corrector without image shake correction of the second optical corrector when the information about the movement position of the first optical corrector is equal to or less than a predetermined value, and performs image shake correction of the second optical corrector when the information about the movement position of the first optical corrector is more than the predetermined value.

Abstract: An imaging apparatus includes an imaging unit configured to convert an object image into an image signal, a vibration detection unit configured to detect a vibration and output information about the vibration, a correction unit moving in a plane orthogonal to an optical axis configured to correct the vibration, a target position calculation unit configured to calculate a target position to which the correction unit is moved based on the information about the vibration output from the vibration detection unit, a position detection unit configured to detect a present position of the correction unit, a calculation unit configured to calculate a difference between the present position and the target position, and a determination unit configured to determine whether a force acting on the imaging apparatus is a gravitational force based on the information about the vibration and a cycle of the vibration.

Abstract: An image capturing apparatus includes a calculation unit which converts shaking detected by a sensor unit into a shaking cancel amount, a correction/driving unit which drives a correction unit using the shaking cancel amount in a plane perpendicular to the optical axis, and corrects blurring of an image formed on an image capturing unit, a zoom position detection unit which detects the current zoom position of a zoom lens, and a center point change unit which changes a center point serving as a movable center of the correction unit in accordance with the zoom position set at either end of the zoom range, or an arbitrary position therebetween. This enables a position of a correction unit to be set which allows optimal image visibility and image blurring correction irrespective of the zoom state.

Abstract: A numerical controller capable of precisely controlling a machine tool having an axis for turning a table with a simple machining program and easily coping with variation of a tool length. A machining path is commanded in a workpiece coordinate system turning with a table. The commanded machining path for linear-motion axes is interpolated based on a commanded machining velocity, to obtain interpolated positions on the machining path. Also, the commanded motions for rotational-motion axes are interpolated to obtain interpolated positions for the rotational-motion axes. The interpolated position for the linear-motion axes is corrected based on the interpolated position of the rotational-motion axes. The servomotors for the linear-motion axes are driven based on the corrected interpolated positions and the servomotors for the rotational-motion axes are driven based on the interpolated positions of the rotational-motion axes.
