CAMERA SYSTEM AND FOCAL POINT DETECTION PIXEL CORRECTION METHOD

摘要

A camera system (1) includes an interchangeable lens (100) and a camera main body (200). The interchangeable lens includes a lens side storage unit (108) that stores pupil related data according to an image height. The camera main body (200) includes an image sensor (208) including a plurality of imaging pixels for imaging, and a plurality of focus detection pixels for focus detection, a main body side storage unit (230) that stores correction data for correcting non-uniformity in illumination distribution by incident light to the focus detection pixel, and a correction unit (2222) that receives the pupil related data from the lens side storage unit (208), and corrects non-uniformity in illumination distribution of outputs of the focus detection pixels based on the correction data and the pupil related data.
