    • An autofocus camera conducts a focus detection operation with one of differently directed sets of photoelectric conversion elements which is given priority according to the detected attitude of the camera. If focusing cannot be effected using the elements given priority, a focus detection operation is automatically conducted with the other elements. Also provided is a camera having a first mode of operation in which focusing detecting operations are conducted which collectively utilize outputs of all of the elements of differently directed sets of photoelectric conversion elements when a first camera attitude is detected, and a second mode of operation in which focusing detecting operations are conducted which collectively disregard the output of at least one conversion element when a second camera attitude is detected.
    • 自动聚焦照相机根据检测到的相机的姿态优先地对不同定向的光电转换元件组中的一个进行焦点检测操作。 如果使用赋予优先权的元素不能进行聚焦,则与其他元素自动进行焦点检测操作。 还提供了具有第一操作模式的相机,其中当检测到第一相机​​姿态时,进行聚焦检测操作,其集体地利用不同定向的光电转换元件组的所有元素的输出,以及第二操作模式 当检测到第二摄像机姿态时,执行聚焦检测操作,其集体地忽略至少一个转换元件的输出。
