1. An image shake correction device that controls a shake correction unit and corrects an image shake of a captured image comprising:
a first calculation unit configured to calculate a first correction amount used for correcting the image shake while shooting moving images based on a shake detection signal;
a second calculation unit configured to calculate a second correction amount used for correcting the image shake while shooting still images based on the shake detection signal, and
a control unit configured to select a correction amount to be used for correcting the image shake from either the first correction amount or the second correction amount and execute control in which an intermediate calculation value of the calculation unit corresponding to the correction amount that has not been selected from either the first calculation unit or the second calculation unit, is updated based on the correction amount that has been selected.
