Claim Text:
1. A shake amount detection device comprising: an acceleration sensor configured to detect an acceleration which is applied to a body; a vibration period detector configured to detect a vibration period during which vibration that becomes a predetermined acceleration is applied to the body; a velocity variation estimation unit configured to estimate a first movement velocity which is a component velocity due to an attitude movement of the body during the vibration period, based on the acceleration detected by the acceleration sensor; a velocity calculator configured to calculate a second movement velocity that is a velocity of the body, based on the acceleration, and to correct the second movement velocity, based on the first movement velocity estimated by the velocity variation estimation unit, in a case of the vibration period as a detection result of the vibration period detector; and a shake amount calculator configured to calculate an image blur correction amount, which is an image movement amount occurring due to the attitude movement of the body, relative to the vibration applied to the body, based on the second movement velocity corrected by the velocity calculator.
