Abstract: An imaging apparatus includes a follow shot control unit and a blur correction unit. The follow shot control unit calculates a panning angular velocity and a tilting angular velocity based on a first or second angular velocity for an image pickup device on the basis of magnitude correlation between the first and second angular velocities for image pickup device and on the basis of an inclination angle immediately before exposure and a ratio between the first and second angular velocities, when a state is a following shot state. The blur correction unit calculates an image blur correction amount on the basis of a difference between the first angular velocity and the panning angular velocity and a difference between the second angular velocity and the tilting angular velocity.

Abstract: A shake amount detection device includes an acceleration sensor. A vibration period detector detects a vibration period during which vibration that becomes a predetermined acceleration is applied to a body. A velocity variation estimation unit estimates a first movement velocity which is a component velocity due to an attitude movement of the body during the vibration period. A velocity calculator calculates a second movement velocity that is a velocity of the body and corrects the second movement velocity in a case of the vibration period as a detection result of the vibration period detector. A shake amount calculator calculates an image blur correction amount relative to the vibration applied to the body, based on the second movement velocity corrected by the velocity calculator.
