Patent ID: 8570385

Claim:
A image stabilization control circuit which drives an optical component or an imaging element of an imaging device according to vibration and which reduces an influence of the vibration on imaging, the image stabilization control circuit comprising: at least one analog-to-digital converter circuit which converts an output signal of a vibration detection element which detects vibration of the imaging device into a digital signal; and a logic circuit which generates a control signal which drives the optical component or the imaging element, based on the output signal of the vibration detection element which is digitized by the analog-to-digital converter circuit, the logic circuit comprising: a pan and tilt judgment circuit which judges a pan operation or a tilt operation of the imaging device; a gain adjustment circuit which adjusts, during imaging, a gain value which amplifies the output signal from the vibration detection element according to a judgment result of the pan and tilt judgment circuit and sets, when the vibration detection element is abnormal, a predetermined value as the gain value which amplifies the output signal from the vibration detection element, regardless of the judgment result of the pan and tilt judgment circuit; a judgment circuit which judges that, if an output value of the vibration detection element obtained when the imaging device is static is not within a normal value range, the vibration detection element is abnormal, based on an amplitude of a signal obtained by amplifying, with the gain value, the output signal from the vibration detection element which is converted to the digital signal by the analog-to-digital converter circuit.
