Abstract:
In an apparatus having a vertical focusing-state detection area and a lateral focusing-state detection area in a cross focusing point, wherein either one of the focusing-state detection areas has a calculation range that is overlapping with the adjacent focusing point, a photographing result desired by a photographer can be obtained without bringing into focus a subject in the focusing point adjacent to the cross focusing point selected by the photographer.
