PURPOSE:To obtain a photographing device capable of focusing even to an object out of the depth of a field, simplified in structure, reduced in cost, moreover miniaturized and light weight by interlocking/controlling the driving means of a shutter blind and of the focusing of a photographing lens. CONSTITUTION:First, the focusing position of the object is detected, and a defocus quantity is calculated. Simultaneously with this, the speeds of the shutter curtains 2 and 3 are set based on exposure information, and lens driving speed is set based on the calculated defocus quantity, and transmitted to a control means 22. On the other hand, a diaphragm value and the slit width 2a of the shutter blind are set based on the exposure information, the shutter speed, the lens, etc., and inputted into the control means 22. Therefore, the shutter blind the lens, etc., are interlocked and driven by respective driving means 30 - 33 of taking up shafts 4a and 4b, a focusing device 11 and a diaphragm device 12. A slit is moved while the focusing is kept constant from the position of a near object 20 toward that of a far object 21. Simultaneously, an exposure is started, the slit is moved, the shutter blinds 2 and 3 are closed. |
