Abstract
Solid-state image sensing elements p and q arranged on an image sensor at a higher density than other solid-state image sensing elements are configured so that the focus error amount due to the axial chromatic aberration of an imaging lens between the solid-state image sensing elements p and q is equal to or larger than an amount corresponding to the depth of focus in a maximum aperture. Also, the imaging lens has a f-number which allows the focus error amount to fall within the range between the two ends of the depth of focus.
