摘要:
A blur correction device comprises a blur correction optical system that corrects an image blur caused by a vibration; a drive device that drives the blur correction optical system; a locking device that locks the blur correction optical system when an image blur correction is not executed; a gravitational direction detection device that detects a direction of a gravitational force applied to the blur correction optical system; and a control device that controls drive of the drive device and the locking device. After stopping an operation executed by the drive device to correct the image blur, the control device controls the drive device so as to reduce an extent to which the blur correction optical system having been locked by the locking device is allowed to move along the gravitational direction.

There is provided a shake detection mechanism in which a determination portion for determining the supporting or fixation condition of a device including the shake detection mechanism is built. The determination portion separately performs detection of a stably supported condition and detection of a non-stably supported condition. The determination portion stops determining the fixation condition when the device is presumably vibrating.

A camera including a flashlight device for emitting a flashlight, a shutter, such that the camera has a flash synchro photographing mode in which the flashlight device emits the flashlight in synchronism with the shutter, a vibration detector for detecting a vibration quantity of the camera, a vibration correcting device for correcting an image blur on the basis of a vibration signal output from the vibration detector. The camera also includes a control device for controlling, while performing flash photographing by use of the flashlight device and driving the vibration correcting device, the shutter so that a maximum shutter time in the flash synchro photographing mode is shorter than or equal to a maximum shutter time in a non-emission of the flashlight. As a result, the flashlight device does not emit the flashlight.

A photographic device has a vibration compensation system with reduced power consumption. The photographic device includes a vibration compensation system with a vibration detection device to detect vibration caused by, for example, a photographer's hand tremor, a vibration compensation device to cause the optical axis of a photographic optical system to change to compensate for the detected vibration, and a control unit to perform processes including vibration compensation control to control the vibration compensation device based on the output of the vibration detection device. The control unit has a low electric current consumption mode which causes its processes to stop to restrain the consumption of electric current, and a normal operation mode during which processes are performed. The photographic device includes a mode changeover device to change the control unit from the normal operation mode to the low electric current consumption mode when a photographic operation has ended. The mode changeover device may also change the control unit from the low electric current consumption mode to the normal operation mode when photographic preparation operations commence. The photographic device also includes an exposure device to perform an exposure on an image forming plane of a photographic optical system, and the control unit operates in a high-speed mode when both exposure control and vibration compensation control are performed at the same time, and in a low-speed mode when exposure control and vibration compensation control are not performed simultaneously.

An apparatus for correcting camera shake due to movement of the hands comprises: a correction unit for correcting for the movement of the hands; a drive unit for driving the correction unit; a control device for controlling the drive unit; a movement detection unit for detecting the amount of the movement of the hands and generating an output corresponding to the detected amount of the movement; and a speed calculating unit for calculating the target driving speed of the correction unit on the basis of the output of the movement detection unit. The control unit controls the drive unit so that the drive unit intermittently drives the correction unit if the target driving speed calculated by the speed calculating unit is smaller than a predetermined value.
