A focus detection apparatus performs focus detection of a phase difference method by using signals from an image pickup element including a first pixel and a second pixel sharing one micro lens, and the focus detection apparatus includes a first saturation detector configured to detect saturation of a first signal obtained from the first pixel, a second saturation detector configured to detect saturation of a second signal obtained from the second pixel, a luminance generating portion configured to generate luminance signals of the first signal and the second signal after detecting the saturations of the first signal and the second signal are detected, and a processor configured to perform a correlation calculation based on the luminance signals. |
