FIELD: physics.
SUBSTANCE: this device allows a simultaneous phase-different and contrast automatic focusing and determination the range proceeding from ratio of compliance between every pixel of shooting object element confined by pupil division means. It allows limitation of radiation from object optical image fed to every pixel of shooting element image. This is effected by radiation from a particular section of outlet pupil of is photographic lens and particular section of photographic lens outlet pupil. Besides, the lens focus magnitude in compliance with focus contrast position or with focus correlation position is evaluated.
EFFECT: higher speed and accuracy of focusing.
