IMAGE PICKUP APPARATUS AND CONTROL METHOD

摘要

An image shake correcting device includes a shake detecting unit configured to detect a shake of an image pickup apparatus; a first optical correcting unit and a second optical correcting unit configured to correct optically an image shake by using a shake signal output from the shake detecting unit; a first position detecting unit configured to detect a position of the first optical correcting unit and output a first position detection signal; and a calculating unit configured to calculate a target position signal for controlling the first optical correcting unit based on the shake signal. The calculating unit calculates a target position signal for controlling the second optical correcting unit by using the signal that is obtained by subtracting the first position detection signal for detecting the position of the first optical correcting unit controlled by the target position signal from the target position signal.
