Embodiment Construction

[0015] The invention is described below with reference to the embodiments shown in the drawings. In an embodiment, the photographing device 1 is a digital camera, and the camera lens 67 of the photographing device 1 has an optical axis LX.

[0016] To explain directions in the embodiment, a first direction x, a second direction y, and a third direction z are defined (see FIG. 1 ). The first direction x is a direction perpendicular to the optical axis LX. The second direction y is a direction perpendicular to the optical axis LX and the first direction x. The third direction z is a direction parallel to the optical axis LX and perpendicular to both the first direction x and the second direction y.

[0017] The imaging part of the photographing device 1 includes a PON button 11, a PON switch 11a, a photometric switch 12a, a release button 13, a release switch 13a, an anti-shake button 14, an anti-shake switch 14a, an indicator 17 such as an LCD monitor, etc., a mirror aperture...

Abstract

An anti-shake apparatus for image stabilizing comprises an angular velocity sensor and a controller. The angular velocity sensor detects an angular velocity. The controller controls the angular velocity sensor and performs an anti-shake operation on the basis of an output signal from the angular velocity sensor. The controller performs a modification of an offset output in the value of the output signal during a predetermined period of the anti-shake operation, and does not perform the modification except for during the predetermined period.

Description

technical field [0001] The present invention relates to an anti-shake device for a photographing device, and in particular to modification of a compensation output of an output signal from an angular velocity sensor at a predetermined time of an anti-shake operation. Background technique [0002] An anti-shake device for photographing equipment is proposed. The anti-shake device corrects the effect of hand shake by making the hand shake correction lens or imaging device move on a plane perpendicular to the optical axis, and the amount of movement corresponds to the amount of hand shake that occurs during the imaging process. [0003] Japanese Unexamined Patent Publication (KOKAI) No. H09-51465 discloses an anti-shake device which, on the basis of detection of a power change, changes the response to an output signal from an angular velocity sensor (gyro sensor) when a power change occurs. The characteristics of the filtered filter to detect the power supply and reduce the co...
