Abstract: A camera which reduces camera shake by adjusting the shutter timing is characterized in that it has a mode for displaying a camera shake amount to allow a photographer to recognize a camera shake. A shutter timing determining section permits shutter release at a timing at which the camera shake amount becomes a predetermined amount or less during a shutter release operation on the basis of the camera shake amount detected by a camera shake detecting section. When a camera shake learning mode is set through an input section, a camera shake amount is converted into a display amount by a display data converting section through a camera shake mode selecting section. This display amount is displayed on a display section in real time while a shutter release button is depressed.
