ABSTRACT:
A focus detection apparatus is disclosed which enables accurate AF operations without a focusing judgment performed in an out-of-focus state even when taking an image including a high-luminance object. The focus detection apparatus generates luminance information of each pixel by using an output from a plurality of pixels of a photoelectric converting element which photoelectrically converts an object image formed by an optical system, and enumerates the number of at least one of pixels whose luminance information is higher than a predetermined luminance and pixels whose luminance information is lower than a predetermined luminance. And, information according to the enumerated result is outputted as the focusing information. The predetermined luminance is set based on the luminance information.
