Abstract

There has been conventionally a problem that the symmetry of pupil division of an imaging device is greatly broken because the position of the exit pupil projected onto the focus detection photo-electric converting part varies with the focal length of the interchangeable lens. According to the invention, a solid-state imaging device having at least one focus area in a part of the effective pixel region where pixels having micro lenses are arranged in a matrix is provided. The solid-state imaging device has a structure in which the micro lens and the focus detection photo-electric converting part of each pixel in the focus area are so arranged as to be separated at a predetermined shift distance. The focus area is composed of pixels having different predetermined shift distances. From among the focus detection photo-electric converting parts, the focus detection photo-electric converting part whose pupil division is the most approximate symmetry is selected to make focus control. With this, pupil division with good symmetry can be carried out, and high-accuracy focus detection adapted to lenses having various exit pupil positions is possible irrespective of the production variation.
