Abstract
The spherical aberration of an imaging lens changes from an object side of image-plane base position Zo toward the other side thereof as a distance from optical axis Zincreases, and formulas 0.02<a/f<0.10 and 0.02<b/f are satisfied. In an imaging apparatus to which the imaging lens is applied, a blur is corrected by performing contrast recovery processing on original image data obtained by imaging. In the formulas, a is the magnitude of spherical aberration from the image-plane base position Zo toward the object side thereof affecting a ray passing through a central part of the pupil of the imaging lens, and b is a sum of a maximum spherical aberration from the image plane base position Zo toward the object side thereof and a maximum spherical aberration from the image plane base position Zo toward the other side thereof, and f is the focal length of the imaging lens.
