Abstract
A control apparatus includes a calculating filter configured to perform a calculation process based on a signal from a shake detector used for an image stabilization, and a correcting filter to which an output signal from the calculating filter is input. The correcting filter includes a boost filter configured to change a gain based on a first frequency and a second frequency, and a notch filter having a center frequency between the first frequency and the second frequency.
