发明名称 Image-shake correcting device
摘要 There is provided an image-shake correcting device that is comprised of a detecting unit that detects shakes of the image-shake correcting device, a filter circuit that cuts off low frequency components of a detecting signal output from the detecting unit, a control circuit that controls the filter characteristic of the filter circuit such that the cutoff frequency of the filter circuit increases as the focal distance of the optical image forming unit becomes longer, and a signal processing circuit that executes signal processing for performing an image-shake correcting operation on an image signal output from the optical image forming unit, according to the detection signal having the low frequency components cut off by the filter circuit, to thereby improve the image stabilization characteristic, which is apt to be degraded on the telephoto side of the optical image forming system of the optical image forming unit.
