    • An extension spring installation structure of a lens barrel includes relatively movable members, one of which supports an optical element, including an extension coil spring biasing the relatively movable members toward each other; and a spring-hook portion and a tilt-restriction portion formed on a relatively movable members. An engaging portion of the extension coil spring is engaged with the spring-hook portion by movement of the extension coil spring toward the spring-hook portion. The spring-hook portion is shaped so as to be prevented from being disengaged from the engaging portion of the extension coil spring even if moved along the axis of the coil spring portion thereof with the engaging portion engaged with the spring-hook portion. The tilt-restriction portion prevents the coil spring portion from moving in a radial direction of the coil spring portion with the engaging portion engaged with the spring-hook portion.

    • A camera has a contrast detector that successively detects contrast data of an object image that is formed on a light-receiving surface of an image sensor, and a focus detector that detects a focused situation on the basis of the contrast data. The camera has, further, a focus adjuster that focuses the object by driving a photographing optical system. When the object is out of focus, the focus adjuster drives the photographing optical system so as to shift the image-formed surface forward and backward. Then, the focus detector detects standard contrast data corresponding to a position before shifting the image-formed surface, forward contrast data corresponding to the forward position, and backward contrast data corresponding to the backward position. The focus adjuster shifts the image-formed surface toward a direction of increase of the contrast data that is obtained from the standard contrast data, the forward contrast data, and the backward contrast data.
    • 相机具有对比度检测器,其连续地检测形成在图像传感器的光接收表面上的对象图像的对比度数据,以及基于对比度数据检测聚焦状态的聚焦检测器。 此外,相机还具有通过驱动拍摄光学系统对焦于对象的焦点调节器。 当对象不对焦时,焦点调节器驱动摄影光学系统,以使图像形成的表面向前和向后移动。 然后,焦点检测器检测对应于移位图像形成表面之前的位置,对应于向前位置的前向对比度数据和对应于向后位置的后向对比度数据的标准对比度数据。 焦点调节器将图像形成的表面朝向从标准对比度数据,向前对比度数据和向后对比度数据获得的对比度数据的增加方向移动。
