Abstract
(EN) An image processing device according to an embodiment of the present invention carries out, upon source image data which is obtained from an image capture element by photography using an optical assembly, a restoration process using a restoration filter based on a point spread function of the optical assembly, obtaining recovered image data. The restoration filter (combination filter, realized filter (Fr)) which is used in this restoration process is generated by a combination of a plurality of base filters (Fb). It is possible to select the base filters (Fb) as appropriate from filters which are pre-verified as being efficacious in preventing image quality degradation.
(FR) Un mode de réalisation de la présente invention porte sur un dispositif de traitement d'image qui effectue, sur des données d'image sources qui sont obtenues en provenance d'un élément de prise de vue par photographie à l'aide d'un ensemble optique, un processus de restauration utilisant un filtre de restauration basé sur une fonction d'étalement du point de l'ensemble optique, obtenant des données d'image récupérées. Le filtre de restauration (filtre de combinaison, filtre réalisé (Fr)) qui est utilisé dans ce processus de restauration est généré par une combinaison d'une pluralité de filtres de base (Fb). Il est possible de sélectionner les filtres de base (Fb) appropriés parmi des filtres qui sont préalablement vérifiés comme étant efficaces pour empêcher une dégradation de qualité d'image.
(JA)  本発明の一実施形態に係る画像処理装置は、光学系を用いた撮影により撮像素子から得られる原画像データに対し、光学系の点拡がり関数に基づく復元フィルタを用いた復元処理を行って、回復画像データを得る。この復元処理で用いられる復元フィルタ(組み合わせフィルタ、実現フィルタFr)は、複数の基底フィルタFbが組み合わされて生成される。基底フィルタFbは、画質劣化を防ぐのに有効であることが予め確認されているフィルタの中から適宜選択されうる。
