International ClassH04N 5/228AbstractAn image stabilization control circuit controls an optical element driving element configured to move 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 an analog-digital conversion circuit configured to receive an analog signal from a position detection element that detects the position of the optical element and convert the input analog signal into a digital signal, and a servo circuit configured to generate a correction signal for correcting the position of the optical element based on an output signal of the analog-digital conversion circuit and output the generated correction signal to the optical element driving element. The servo 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.Other References
