Abstract
In a restoration apparatus, an estimating unit divides a captured original image into a plurality of local pixel blocks, and estimates an luminance level of airlight in each of the plurality of local pixel blocks. A calculating unit directly calculates, from a particle-affected luminance model, a luminance level of each pixel of each of the plurality of local pixel blocks in the original image to thereby generate, based on the luminance level of each pixel of each of the plurality of local pixel blocks, a restored image of the original image. The particle-affected luminance model expresses an intrinsic luminance of a target observed by the image pickup device as a function between the luminance level of airlight and an extinction coefficient. The extinction coefficient represents the concentration of particles in the atmosphere.
