IMAGE FORMING ELEMENT AND IMAGE FORMING APPARATUS AND PHOTOGRAPHIC SYSTEM HAVING SAID ELEMENT Russian patent published in 2013 - IPC G02B7/34 

FIELD: physics.

SUBSTANCE: image forming element includes a pixel for photoelectric conversion of light from a lens, first and second focus detection pixels and an electrode part in the first and second focus detection pixels. Electrode parts in the first and second focus detection pixels are situated in the ends of the photoelectric conversion part, which are opposite each other in the direction of separation of the pupil of the first and second focus detection pixels.

EFFECT: high accuracy of determining focusing by reducing the effect of light on the transmitting electrode.
