  • Patent number: 8928762
    Abstract: In an embodiment, when a sleep mode is turned off, if vibration less than a limit value occurs, the sleep mode is turned on and a hand shake correction unit is turned off so that power consumption may be reduced. Moreover, when the sleep mode is turned on, if vibration greater than a limit value occurs, the sleep mode is turned off and the hand shake correction unit is turned on so that an image blur does not occur. In another embodiment, when the sleep mode is turned off, if vibration less than a limit value occurs, the hand shake correction unit is turned on in the state where the sleep mode is turned on and a HPF is turned on so that an image blur is prevented from occurring due to a shock caused by pushing a release button or shock caused by opening or closing a shutter.
