Abstract:
The apparatus of the invention is characterized by executing radius-of-rotation calculation operation for calculating a radius of rotation from a velocity change found by time integration of acceleration, and an angular velocity; velocity calculation operation in which during a given time from a start of exposure, velocity is calculated based on the angular velocity and the radius of rotation calculated before the start of exposure, and after a lapse of the given time, the acceleration is cumulatively added to the velocity detected during the given time to calculate the velocity, and amount-of-movement calculation operation for time-integrating the velocity calculated in the velocity calculation operation to calculate the amount of movement.
