1. An image pickup apparatus comprising:
an image sensor including first pixels and second pixels that are arranged two-dimensionally and that respectively receive visible light and invisible light entering through an image pickup optical system, wherein each of the first pixels and the second pixels has photoelectric conversion elements that receive light beams passing through different pupil areas of the image pickup optical system;
a memory device that stores a set of instructions; and
at least one processor that executes the set of instructions to:
detect a first defocus amount based on signals output from the first pixels and a second defocus amount based on signals output from the second pixels as focus detection results;
determine a position that internally divides the first defocus amount and the second defocus amount as a lens position of the image pickup optical system; and
determine an exposure condition of a time of image pickup with the image sensor according to the focus detection results.
