Patent ID: 8068139

Claim:
An image stabilization control circuit, comprising: a high-pass filter configured to remove a low-frequency component from an output signal of a vibration detection element; a movement amount calculation circuit configured to calculate a movement amount of an imaging apparatus based on an output signal of the high-pass filter; a centering processing circuit configured to apply a subtraction process in which a predetermined value is subtracted from an output signal of the movement amount calculation circuit such that an optical element is prevented from approaching a limit point of a movable range and output an obtained value to a servo circuit; an analog-digital conversion circuit configured to receive an analog signal from a position detection element that detects a position of the optical element and convert the input analog signal into a digital signal; and the servo circuit configured to generate a correction signal for correcting the position of the optical element based on the output signal of the analog-digital conversion circuit and output a generated correction signal to an optical element driving element, wherein the servo circuit includes a digital filter circuit and a register, and the digital filter circuit performs filter processing based on a filter coefficient stored in the register, and the servo circuit generates the correction signal based on a sum of an output signal of the position detection element that detects the position of the optical element and an output signal of the centering processing circuit.
