The present invention provides a solid state image sensing device capable
of performing high-speed focal point adjustment without using a special
optical system and a photographing apparatus including the device.
Multiple photoelectric conversion elements are arranged and photoelectric
conversion elements for auto focus (AF) are arranged between them.
Concave and convex forms are formed, and the photoelectric conversion
elements for rear side and front side AF are disposed in the concave and
convex portions. The moving direction of a focusing lens is determined
based on the difference between outputs of the photoelectric conversion
elements for rear side and front side AF and the focusing lens is moved
to the position where the contrast value obtained from the photoelectric
conversion elements becomes the maximum.
