ABSTRACT:
This invention relates to a focus detecting apparatus using an area sensor as an AF sensor, and particularly provides a focus detecting apparatus in which when any area in a scene is designated and the focus state in that area is to be detected, the output from an area on the sensor corresponding to the designated area of the scene is read and processed on the basis of the information of an area on the area sensor corresponding to the designated area of the scene pre-memorized in a memory circuit.
