<P>PROBLEM TO BE SOLVED: To perform exposure control over right and left imaging systems in optional timing. Ž<P>SOLUTION: An electronic shutter of an imaging device of the right imaging system 11 and an electronic shutter of an imaging device of the left imaging system 12 are opened nearly at the same time to start exposure to the imaging device of the right imaging system 11 and exposure to the imaging device of the right imaging system 12 nearly at the same time. A mechanical delay of a right mechanical shutter of the right imaging system 11 is larger than that of a left mechanical shutter of the left imaging system 12, so that a mechanical shutter driving pulse is outputted to the right mechanical shutter earlier than to the left mechanical shutter by the difference between the mechanical delay of the right mechanical shutter and the mechanical delay of the left mechanical shutter. Consequently, the right mechanical shutter and left mechanical shutter are closed nearly at the same time. Consequently, the right imaging system 11 and the left imaging system 12 have completely the same photography start timing and photography end timing. The right imaging system 11 and the left imaging system 12 can therefore be equalized in exposure and in a position of an object to be imaged. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
