ABSTRACT:
A focus adjustment device includes an image sensor that includes imaging pixels for capturing an image formed via an imaging optical system and focus detection pixels for detecting a focus adjustment state at the imaging optical system through a first pupil division-type image shift detection method, a focus detector that detects a focus adjustment state at the imaging optical system through a second pupil division-type image shift detection method different from the first pupil division-type image shift detection method, and a focus adjustment controller that executes focus adjustment for the imaging optical system based upon the focus adjustment states detected by the image sensor and the focus detector.
