In this research, the real-time super-resolution system used as a base is to output images obtained from the camera to the display after pixel interpolation by doubling the height and width using the ICBI algorithm. For practical use, we have researched and developed a function to enlarge an arbitrary area by doubling the number of interpolation pipeline stages of ICBI, which can further enlarge the video image by interpolating pixels twice as much as the vertical and horizontal. However, this method increases the number of pipeline stages, resulting in hardware resource constraints, increased power consumption, etc. Therefore, we thought that 50 frames per second was unnecessary for security and surveillance applications, and created a real-time super-resolution system with variable magnification that displays 25 frames per second for 4x video and 16.7 frames per second for 8x video, using the interpolation pipeline of ICBI in a timedivision manner, with almost no increase in hardware requirements.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://id.nii.ac.jp/1001/00222680/","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) by the Information Processing Society of Japan","subitem_rights_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2188-8833","subitem_source_identifier_type":"EISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松本 尚","creatorNameLang":"ja"},{"creatorName":"まつもと たかし","creatorNameLang":"ja-Kana"},{"creatorName":"Takashi Matsumoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1000070240728","nameIdentifierScheme":"KAKEN2","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000070240728"}]},{"creatorNames":[{"creatorName":"近藤 真由","creatorNameLang":"ja"},{"creatorName":"こんどう まゆ","creatorNameLang":"ja-Kana"},{"creatorName":"Mayu Kondo","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateValue":"2025-02-03"}],"fileDate":[{"fileDateType":"Available","fileDateValue":"2025-02-03"}],"url":{"objectType":"fulltext","url":"http://id.nii.ac.jp/1001/00222680/"}}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"FPGA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ICBI","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Super-resolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ICBI を用いた倍率可変リアルタイム超解像システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ICBI を用いた倍率可変リアルタイム超解像システム","subitem_title_language":"ja"}]},"item_type_id":"10001","owner":"83","path":["1708568841932"],"publish_date":"2025-02-03","publish_status":"0","recid":"2005976","relation_version_is_last":true,"title":["ICBI を用いた倍率可変リアルタイム超解像システム"],"weko_creator_id":"83","weko_shared_id":-1},"updated":"2025-02-17T07:07:57.603448+00:00"}
