Automatic focus state detecting apparatus.

摘要

An automatic focus state detecting apparatus comprising a detector, a discriminator, and a selector. The detector is capable of focus state detection respectively in a narrow detecting area and a wide detecting area present in the object field. The discriminator detects the relative movement between the apparatus and an object present in the detecting areas. When the relative movement is detected by the discriminator, the selector causes the detector to effect the focus state detection in the wide detecting area.
