摘要:
An apparatus includes a vibration correction unit configured to correct an image shake occurring due to vibration, a first detection unit configured to detect an angular velocity of the vibration, a second detection unit configured to detect an acceleration of the vibration, a calculation unit configured to calculate a correction value based on the output of the first detection unit and the output of the second detection unit, an output correction unit configured to correct an output of the first detection unit based on the correction value and to change a frequency characteristic of a signal based on the output of the first detection unit to apply an apparent frequency-dependent characteristic to the correction value, and a driving unit configured to drive the vibration correction unit based on an output of the first detection unit, an output of the output correction unit, or a combined output thereof.
