In an image blur prevention device for a camera, the limit delay time for image blur reduction is set to be changeable so as to reduce the influences of camera shakes on photographing operations, so as to realize high operability. A shake determining section determines the image blur state on the current image plane on the basis of the camera shake state detected by a shake detecting section. As a result, information corresponding to the level of the current image blur state is sent to an exposure control section. On the basis of image blur state information from the shake determining section when an exposure start instruction signal is received, limit delay time information set in a limit delay time setting section, and the count result obtained by a timer section, the exposure control section determines whether to start an exposure operation in accordance with the state of a release operating section. If it is determined that exposure should be started, a shutter unit is driven by a shutter drive section to perform an exposure operation. If it is determined that exposure should not be started, the shutter drive section is stopped, and no exposure operation is performed.
