    • A focus detecting system for detecting a focusing state is adaptable to various optical systems of different specifications. The focus detecting mode of the system changes according to the specifications of the associated optical system and the focus detection signal is normalized to compensate for changes in the brightness, contrast and pattern of the object being focussed. Additionally, the field of view may be varied in accordance with the selected optical system and the focus detection signal is normalized to compensate for changes in the brightness, contrast and pattern of the object being focussed. Additionally, the field of view may be varied in accordance with the selected optical system.
    • 用于检测聚焦状态的聚焦检测系统适用于不同规格的各种光学系统。 系统的焦点检测模式根据相关光学系统的规格而变化,并且对焦点检测信号进行归一化以补偿被聚焦物体的亮度,对比度和图案的变化。 另外,视场可以根据所选择的光学系统而变化,并且对焦点检测信号进行归一化以补偿被聚焦的对象的亮度,对比度和图案的变化。 另外,视场可以根据所选择的光学系统而变化。
