摘要

An image pickup apparatus is provided with an image blur correction apparatus that corrects image blur of a captured image by using a shake detection signal that has been detected by a shake detection unit. A controller for image blur correction generates a first signal obtained by multiplying an output signal of the shake detection unit by a first correction ratio gain. A second signal is generated by multiplying the sum of the output signal of the shake detection unit that has passed through a low-pass filter and the output signal of the shake detection unit that has passed through a high-pass filter by a second correction ratio gain. A target generating unit generates a target value signal for image blur correction based on the sum of the first and second signals and drives the shake correction unit.
