ABSTRACT:
An image sensor captures an image formed through an optical system and includes a plurality of types of imaging pixels with spectral sensitivity characteristics different from one another, two dimensionally disposed in a predetermined array. The image sensor includes a plurality of focus detection pixel rows that are disposed so as to occupy part of the predetermined array and extend along a plurality of directions intersecting each other, each made up with a plurality of focus detection pixels set along one of the plurality of directions, and the focus detection pixel rows are used to detect a focusing condition of the optical system. A focus detection pixel occupying a position at which the focus detection pixel rows intersect is set at a position equivalent to a position of an imaging pixel with specific spectral sensitivity characteristics corresponding to imaging pixels disposed with a highest level of density in the predetermined array.
