To obtain an image without blurring in spite of a situation where a hand shake occurs by stopping exposure and compensating a shortage portion concerning proper exposure by means of amplifying a signal which is outputted from an imaging device when the hand shake ≥ a threshold level is detected during still image photographing.

When a shake quantity detected by a hand shake detection 6 exceeds a previously set threshold level, a diaphragm 2 is perfectly closed instantaneously and the conversion of an image into an electric charge is stopped. Then it is judged that the remaining one-third of a storage time is usage impossible since blurring is too large and, then, invalidated. Then the electric charge is stored concerning only the two-thirds of the storage time for obtaining a proper signal quantity so that the signal quantity to be read is two-thirds of the planned quantity. Then the gain of an amplifier 4 is set to be 3/2 times. By the operation, the image is constituted only by the electric charge which is exposed till the moment when the hand shake occurs even in the case that the hand shake occurs in the midst of image exposure so that the image without blurring is obtained.
