Abstract
Abstract A camera is provided with: a detector for detecting a shake amount of the apparatus with respect to an object at an interval; a calculator for calculating a shake speed and a shake acceleration rate based on detected shake amounts, and calculates an estimative shake amount based on a calculated shake speed, a calculated shake acceleration rate, and a coefficient k ( 0< k< 1 ) on an assumption that a shake is uniformly accelerated motion, the coefficient k being a multiplier for the calculated shake acceleration rate; and a corrector for executing a shake correction in accordance with a calculated estimative shake amount.
