At least three of s, . . . , and Sare mutually different and a relation of s≧sis satisfied, where s, . . . , and srepresent mean luminances of images obtained from the first through nth pixels, respectively. The first optical region and the nth optical region are positioned not to be point-symmetric to each other with respect to the optical axis.
