ABSTRACT:
In an image stabilizing apparatus having blur detecting means for detecting the blur of the image of a camera and blur correcting means for correcting the blur of the image of the camera on the basis of the output of the blur detecting means, control is effected so that the supply of electric power to the blur detecting means may be started in response to the camera being released from a state which renders it unable to photograph, and thereafter the supply of electric power to the blur correcting means may be started in response to an operating portion for effecting the photographing by the camera being operated, whereby the wasteful supply of electric power is prevented from being effected to the blur correcting means during the initial stabilizing period required until the blur detecting means performs its proper operation after the start of the supply of electric power thereto, thereby preventing the waste of electric power and further preventing the photographer from being given a malaise.
