摘要： A camera having a lens shutter mechanism in accordance with the present invention comprises sectors lying in a lens frame and forming a predetermined exposure aperture, a drive ring for opening and closing the sectors, a high-speed sector opening lever and a low-speed sector opening lever which drive the drive ring through an interlock lever, a plurality of springs having different strengths and constraining the high-speed sector opening lever and low-speed sector opening lever, a sector closing lever for driving the high-speed sector opening lever and low-speed sector opening lever in a direction causing the sectors to close, a mode changing member for changing shutter speeds by selecting whether both or either of the high-speed sector opening lever and low-speed sector opening lever should be driven, a charge cam gear for resetting the shutter mechanism to an initial position after exposure is completed, and a groove bored along the optical axis in a camera body and designed to guide the drive ring along the optical axis when the lens frame collapses and to restrain the drive ring from rotating about the optical axis after the lens frame completes collapsing. Only a minimum number of required members are disposed in a lens frame and the remaining members are arranged in a camera body. This results in a compact camera.

摘要： A camera shutter system includes a matrix memory, an arrangement for determining the initial speed of a shutter sector, and a source of exposure values. The memory stores shutter-exposure pulse data elements, and is addressed by functions of the determined speed and the exposure values. A motor coupled to the sector is controlled in response to an accessed pulse data element. The data elements may relate only to variable portions of movement of the shutter, and be added to fixed values in order to minimize the size of the memory.

摘要： The present technology relates to a power controller, a power control method, and a program which appropriately supply power to an actuator for driving a shutter and an actuator for camera shake correction. A power controller includes a shutter controller for controlling a shutter driving unit, a camera shake correction controller for controlling a camera shake correction driving unit, and a power amount setting unit for setting amounts of power to be allocated to the shutter driving unit and the camera shake correction driving unit according to a set shutter speed. The power amount setting unit allocates the amount of power to be supplied to the camera shake correction driving unit when the shutter speed is equal to or less than a predetermined speed to the shutter driving unit in a case where the shutter speed is faster than a predetermined speed. The present technology available for an image pickup device.
