Abstract
An imaging apparatus includes an image sensor including pixel units for photoelectrically converting an object image formed through a photographic optical system, each of the pixel units including at least three photoelectric conversion elements arranged in a plane in which the object image is formed; a focus detector which performs a phase-difference focus detection operation using an image signal obtained by the photoelectric conversion elements; and an image generator which generates an image from the image signal. The at least three photoelectric conversion elements of each of the pixel units include at least three different types of spectral sensitivity characteristic elements which have mutually different in spectral sensitivity characteristics. Identical spectral sensitivity characteristic elements of the spectral sensitivity characteristic elements that are respectively provided in adjacent two of the pixel units are symmetrically arranged in one of a lateral and a longitudinal direction.
