Claim 16:
17. An image stabilization method comprising:
detecting a motion vector from images repeatedly output from an image sensor;
obtaining an angular velocity of shake of an image capturing apparatus;
calculating a first image stabilization coefficient to be used for calculating an amount of translational shake based on the motion vector and the angular velocity;
calculating a second image stabilization coefficient to be used for calculating an amount of translational shake based on acceleration and the angular velocity of shake of the image capturing apparatus;
selecting either of the first image stabilization coefficient or the second image stabilization coefficient based on information about accuracy of detection of the motion vector; and
calculating an amount of translational shake using selected one of the first image stabilization coefficient or the second image stabilization coefficient,
wherein, the second image stabilization coefficient is selected in a case where the information indicates that the accuracy is low, and the first image stabilization coefficient is selected otherwise.
