发明名称 Photographic device having a vibration compensation function with reduced power consumption
摘要 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.
