Abstract
According to the present invention, even if variation (estimation variation) is caused in a subject distance estimated at the time of imaging when restoration processing of a taken image is performed using a restoration filter corresponding to the subject distance, since an optimal restoration filter that conforms to a subject distance taking into account the maximum infinity-side estimation variation and does not cause overcorrection is selected, it is possible to prevent resolution degradation due to overcorrection and achieve the improvement of resolution by the restoration filter.
