Claim 3:
4. The image stabilization apparatus according to claim 1, wherein the determination unit estimates image plane velocity of translational shake on an imaging plane of the image sensor from image plane velocity of angular shake on the imaging plane of the image sensor calculated based on newly detected angular velocity, based on a ratio between image plane velocity of angular shake calculated in the past based on the angular velocity of shake of the image capturing apparatus and image plane velocity of translational shake calculated in the past based on the motion vector for calculating the first image stabilization coefficient, and the determination unit determines that the accuracy is low if a ratio of the estimated image plane velocity of translational shake to the image plane velocity of angular shake used for the estimation is lower than a predetermined ratio.
