Abstract
An image stabilization control circuit controls an optical element driving element that moves an optical element provided in an imaging apparatus based on an output signal of a vibration detection element provided in the imaging apparatus. The image stabilization control circuit includes a high-pass filter that removes a low-frequency component from an output signal of the vibration detection element. A movement amount calculation circuit calculates a movement amount of the imaging apparatus based on an output signal of the high-pass filter. A servo circuit generates a correction signal for correcting the position of the optical element based on an output signal of the movement amount calculation circuit and outputs the correction signal to the optical element driving element. The movement amount calculation circuit includes a digital filter circuit and a register. The digital filter circuit performs filter processing based on a filter coefficient stored in the register.
