<P>PROBLEM TO BE SOLVED: To solve the problem in that the degree of coincidence of two images decreases due to imperfect separation of two luminous fluxes according to the direction of linear polarization and accordingly focus detection accuracy degrades. <P>SOLUTION: The imaging device includes: a pupil split polarization means 110 by which light 100 from a subject passing through the emission pupil of a photographing optical system is split into a pair of luminous fluxes 102 and 103 different from each other in gravity center and polarization characteristic; and an imaging element 211 in which pixels 212 and 213 that selectively receive either the luminous flux 102 or 103 are two-dimensionally arranged. <P>COPYRIGHT: (C)2008,JPO&INPIT |
