Patent ID: 8811809

Claim:
An image stabilization apparatus comprising: a vibration correction unit that corrects image blur due to vibrations; a first vibration detection unit that detects an angular velocity of vibrations; a first calculation unit that calculates a rotational shake correction amount based on an output from the first vibration detection unit; a second vibration detection unit that detects vibrations by using a method different from that of the first vibration detection unit; a second calculation unit that calculates a correction value from outputs from the first vibration detection unit and the second vibration detection unit and calculates a translational shake correction amount based on the correction value and the output of the first vibration detection unit; a driving unit that drives the vibration correction unit based on at least one of the rotational shake correction amount and the translational shake correction amount; and a first changing unit that, when a main object accounts for a smaller proportion of an entire screen, changes the translational shake correction amount so as to be smaller than that when the main object accounts for a larger proportion.
