A shake amount detecting section repeatedly detects shaking of a camera in a sampling time interval shorter than a hand shaking cycle. An exposure calculating section calculates a shutter speed based on the sensitivity of a film and the brightness of an object. A data processing section acquires processed data from a product of the shutter speed and the amount of shaking, every time the amount of shaking is detected. A storage section stores the processed data output. A shake amount predicting section receives the processed data and the processed data stored in the storage section to predict the total amount of shaking while the shutter is open, every time the processed data is output from the data processing section. A release switch instructs the beginning of an exposing operation on the film. A shutter enable discriminating section discriminates permission of a shutter release when a latest predicted total amount of shaking during shutter opening, output from the shake amount predicting section, is equal to or smaller than a predetermined amount, every time the release switch is operated and the shake amount predicting section predicts the total amount of shaking. A shutter controller starts opening the shutter based on a signal from the shutter enable discriminating section and controls an exposure time based on the shutter speed.
