发明名称 Focus control apparatus, image sensing apparatus, and control method therefor
摘要 A control method of detecting an object image to be focused from a sensed image, setting a focus detection area in detecting an in-focus state of a photographing optical system, and exercising control such that the photographing optical system is moved based on a signal output in the focus detection area to carry out focus control, wherein, in the setting of the focus detection area, a first focus detection area corresponding to an object to be focused detected from the sensed image and a second focus detection area which is larger than the first focus detection area are set, and in the focus control, control is exercised such that the photographing optical system is moved based on output signals in the set first and second focus detection areas.
