However, its computation is rather heavy because the standard Z-buffer algorithm is applied on every pixel of an image to begenerated. In this paper, we introduce a multiple pinhole algorithm in which images are generated by accumulating a set of shifted pinhole images, and discuss the improvement of both algorithms by evaluating the trade-off between the reduction of computation time and the degradation of image quality.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110002674393","subitem_relation_type_select":"NAID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
