Abstract:
1. An image-shake correcting device for an image pickup apparatus having an optical image forming unit that forms an image, comprising: a detecting unit that detects a shake of the image-shake correcting device; a filter circuit that cuts off low frequency components of a detection signal output from said detecting unit, said filter circuit being variable in cutoff frequency; a panning determining circuit that determines whether or not panning of the image pickup apparatus is being carried out, according to the detection signal output from said detecting unit; a first control circuit that provides control to change the cutoff frequency of said filter circuit according to results of the determination by said panning determining circuit; a second control circuit that provides control to change a minimum frequency of a range of the cutoff frequency of said filter circuit to be changed by said first control circuit in a manner such that the minimum frequency is higher as a focal distance of said optical image forming unit is longer while the focal distance is above a predetermined value; and a signal processing circuit that carries out signal processing for performing an image-shake correcting operation on an image signal output from said optical image forming unit, according to the detection signal having the low frequency components cut off by said filter circuit.
