To start exposure at a timing when the influence of image deterioration suppressed in a camera including a shake correcting member.

The shake correcting apparatus for correcting an image shake in an object image formed on an imaging element through an imaging optical system includes: a shake detecting part 14 that detects the camera shake; the shake correcting member 151 that corrects the image shake on the imaging element 6 by changing the relative positions of the imaging optical system 2 and the imaging element 6 in a direction perpendicular to the optical axis, based on the detected shake; a position predicting means 712 that predicts the position of the shake correcting member 151; a target position predicting means 713 that predicts the drive target position of the shake correcting member 151 based on the predicted position; an error calculation means 716 that calculates an error between the position of the shake correcting member 151, predicted by the position predicting means 712, and the drive target position predicted by the target position predicting means 713; and a timing determination means 717 that determines the timing to start the exposure based on the error calculated by the error calculation means 716.
