Abstract:
An apparatus for auto-focusing detection, a camera applying the same, and a method for calculating a distance to a subject are disclosed. The camera calculates a focusing control state based on synthetic image data output as an image passing through a pupil split unit provided with a filter arranged at one or more of the at least two holes as taken by an image pickup unit.
