1. An apparatus comprising:
- a detector which detects a shake amount of the apparatus with respect to an object at an interval;
a calculator which calculates 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 which executes a shake correction in accordance with a calculated estimative shake amount.
