An imaging apparatus includes an imaging unit operable to capture a subject image via an optical system and generate image data, a regulating unit operable to regulate an exposure amount for the imaging unit; a shake detector operable to detect a shake of the imaging apparatus; an operation unit capable of being in a first operating state and a second operating state; and a controller operable to control the recording unit to record the image data generated by the imaging unit in the recording medium, when the operation unit is in the first operating state. The controller determines whether or not the operation unit is in the second operating state before the first operating state, and regulates an exposure time of the regulating unit based on the determination result and the shake of the imaging apparatus detected by the shake detector.
