发明名称 FOCUSING APPARATUS
摘要 A focusing apparatus includes a setting unit configured to set a focus detection area to be focused among a plurality of focus detection areas, a memory configured to store focus correction information based on a focusing status of a focus lens in each of the focus detection area to be focused and another focus detection area, a focus detection unit configured to detect the focusing status of the focus lens in the other focus detection areas, and a focusing unit configured to move the focus lens for focusing based on the focusing status of the focus lens detected in the other focus detection area. The focusing unit corrects the focusing status of the focus lens detected in the other focus detection area based on the focus correction information stored in the memory and achieves focusing.
