Abstract
In an inspection apparatus according to one aspect of the present invention, a processing apparatus includes: a profile data generation unit that divides each of a plurality of images according to a circumferential position to generate profile data in which a radial direction position and luminance data are associated with each other; a deconvolution operation unit that carries out a deconvolution operation using a one-dimensional point spread function to generate deconvolution operation data based on the profile data; an estimation unit that estimates estimation data of the deconvolution operation data in a desired focus position in the optical axis direction using the deconvolution operation data; and a synthesis unit that synthesizes the estimation data estimated by the estimation unit for each radial direction position to generate the image in the desired focus position.
