摘要： A digital camera comprises two photographing systems which are independent of and substantially identical to each other, and each of which includes a photographing optical system and an image pickup device. The photographing optical system is configured to include a photographing lens, a focusing lens and an aperture stop. The focusing lens of one of the photographing systems is driven stepwise from a first predetermined position at which it is to be located when a focusing position lies at an infinite distance, toward a second predetermined position at which it is to be located when the focusing position lies at the closest distance, while the focusing lens of the other photographing system is driven stepwise from the second predetermined position toward the first predetermined position every step width. The contrasts of images formed by the respective photographing systems are evaluated while the two focusing lenses are being moved, and a position corresponding to the maximum value of the contrasts is determined as the focusing position.
摘要翻译：数码相机包括彼此独立且基本相同的两个拍摄系统，并且每个照相系统包括拍摄光学系统和图像拾取装置。拍摄光学系统被配置为包括拍摄镜头，聚焦透镜和孔径光阑。当聚焦位置处于无限距离时，其中一个拍摄系统的聚焦透镜将从其位于待定位的第一预定位置逐步地朝着待聚焦位置处的第二预定位置被驱动位于最接近的距离处，而另一拍摄系统的聚焦透镜从步骤宽度的第二预定位置朝着第一预定位置逐步驱动。在移动两个聚焦透镜的同时评估由相应的拍摄系统形成的图像的对比度，并且将与对比度的最大值相对应的位置确定为聚焦位置。

摘要： Maximum and minimum aperture sizes are regulated with regard to a diaphragm in order to secure predetermined optical capability in an optical unit which includes a taking lens and the diaphragm. In normal taking, the diaphragm is used within a normal taking range from the maximum to the minimum aperture sizes. In the present invention, an aperture size which is larger than the maximum size and a size which is smaller than the minimum size (extra aperture size or extra small size) are respectively set at outside the range that secures the capability. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure (AE) adjustment, auto focus (AF) adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels.
