    • A compact focus state detection device having a plurality of focus state detection areas at the center of and away from the center of the photo field. A first focus state detection optical system has focus state detection areas away from the center of the photo field and in a direction substantially perpendicular to the radial direction from the center point. The optical axis of each re-imaging lens of the first focus state detection optical system is decentered toward the optical axis of the shooting lens from the center of each corresponding aperture stop. Therefore, when focus state detection light rays pass through the re-imaging lens, the exit direction of the light rays deflects toward the optical axis of the shooting lens.
    • 一种紧凑的聚焦状态检测装置,其具有在照相场的中央和远离中心的多个聚焦状态检测区域。 第一焦点状态检测光学系统具有远离光场中心的焦点状态检测区域,并且在距离中心点大致垂直于径向方向的方向上。 第一焦点状态检测光学系统的每个重新成像透镜的光轴从每个对应的孔径光阑的中心偏向于拍摄镜头的光轴。 因此,当聚焦状态检测光线穿过再成像透镜时,光线的出射方向朝向拍摄镜头的光轴偏转。
