Abstract
An image blur information acquisition apparatus includes a first acquisition unit configured to acquire a first shake detection result from a first shake detection unit configured to detect a shake amount of an image capturing apparatus based on a motion vector, a second acquisition unit configured to acquire a second shake detection result from a second shake detection sensor configured to detect a rotational angular velocity, and an estimation unit configured to estimate an amount of offset included in the second shake detection result, based on the first shake detection result and the second shake detection result, wherein the estimation unit is configured to set degree of change of estimation value by updating the offset amount based on a difference between the second shake detection result and the first shake detection result.
