Image stabilizer

Abstract

The present invention provides an image blur correction apparatus, comprising: a blur detection device which detects a vibration applied to an optical system and outputs a blur signal in accordance with the detected vibration; an image blur correcting device which performs image blur correction to cancel out an image blur that is produced by a vibration applied to the optical system, based on a blur signal output from the blur detection device; a determining device which determines whether or not a determining condition that a size of a correction amount indicating a size of an image blur correction according to the image blur correcting device at least exceeds a predetermined threshold value, is fulfilled; and a correction switching device which, when the determining device determines that the determining condition is fulfilled, switches a mode of image blur correction performed to a mode of a pan/tilt operation.
