摘要: A focus detection device includes: a defocus information unit that detects phase difference indicating manifested by pair of images formed with light fluxes having passed through different areas photographic optical system and based upon the information; correction executes for correcting information, detected unit, in correspondence to predetermined direction extending between first orthogonally intersects an axis radially extends from second direction.
