1. A solid-state imaging device comprising:
a plurality of photo receivers arranged in a two-dimensional array on a semiconductor substrate, the photo receivers receiving exit light from an imaging optical system; and
a plurality of condensing lenses arranged over said plurality of photo receivers, respectively,
wherein:
said plurality of photo receivers are arranged at equal pitches;
said plurality of condensing lenses are arranged at smaller pitches than said plurality of photo receivers in a region where an image height is zero;
said plurality of condensing lenses are arranged at greater pitches in a region where the image height is larger than zero than in the region where the image height is zero; and
said plurality of condensing lenses are arranged at smaller pitches than said plurality of photo receivers in a central part of an image area, and said plurality of condensing lenses are arranged at greater pitches than said plurality of photo receivers around the image area.
