Abstract

PURPOSE:To prevent the failure in photographing owing to camera shake by automatically changing shutter second time to camera shake threshold time and adjusting a diaphragm value when the preset or operated shutter second time exceeds the camera shake threshold time. CONSTITUTION:The shutter speed Tv value necessary for obtaining correct exposure is calculated by making prescribed operation by one-step depression of a shutter button. When this calculated shutter second time exceeds the camera shake treshold time, the Tv value is changed to a camera shake threshold value TvH and an aperture value Av is calculated by making prescribed operation. Since the camera shake threshold time varies with the focal lengths of a lens mounted, focal length information is introduced from lens side, and TvH value is adjusted according to the focal length. With such constitution, the failure in photographing is prevented.
