Patent ID: 8243151

Claim:
A vibration prevention control circuit that drives an optical component of an imaging device according to vibration and that reduces influence of the vibration on imaging, the vibration prevention control circuit comprising: at least one analog-to-digital converter circuit that converts an output signal of a vibration detection element, which detects vibration of the imaging device, and an output signal of a position detection element which detects a position of the optical component, into digital signals; and a logic circuit that generates a control signal which drives the optical component, based on the output signal of the vibration detection element, which is digitized by the analog-to-digital converter circuit, and the output signal of the position detection element which is digitized by the analog-to-digital converter circuit, wherein the logic circuit comprises a phase delay circuit that increases phase delays of the output signal of the vibration detection element as the frequency becomes higher, without changing an intensity in a predetermined frequency band, and outputs the processed signal.
