As a result, there is increasing demand for an oxygen saturation meter that can measure a decrease in oxygen saturation, which is one index for evaluating the acute exacerbation of symptoms. Generally, the method adopted for measuring oxygen saturation relies on a relation between the amount of light absorption by blood at particular wavelengths, and the blood's oxygen saturation. Therefore, in this research, we focused on the difference in the absorption characteristics of hemoglobin for red, green, and blue light, and we proposed and evaluated a method for estimating oxygen saturation using visible light. As a result, we suggest that oxygen saturation can be estimated using a non-contact RGB camera.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"95971","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IWAI, Morio"}]},{"nameIdentifiers":[{"nameIdentifier":"95972","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Koichiro"}]},{"nameIdentifiers":[{"nameIdentifier":"95973","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HONMA, Naoki"}]},{"nameIdentifiers":[{"nameIdentifier":"95974","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATO, Atushi"}]},{"nameIdentifiers":[{"nameIdentifier":"95975","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ジョーンズ, マイケル"}]}]},"item_16_link_13":{"attribute_name":"抄録（URL）","attribute_value_mlt":[{"subitem_link_text":"RGBカメラを用いた非接触酸素濃度推定技術に関する研究","subitem_link_url":"https://www.jstage.jst.go.jp/article/jsmbe/Annual59/Abstract/Annual59_400/_article/-char/ja/"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本生体医工学会"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.11239/jsmbe.Annual59.400","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021 日本生体医工学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18814379","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1347443X","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学理工学部"},{"subitem_text_value":"岩手大学理工学部"},{"subitem_text_value":"岩手大学理工学部"},{"subitem_text_value":"株式会社エクォス・リサーチ"},{"subitem_text_value":"株式会社エクォス・リサーチ"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岩井, 守生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 宏一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本間, 尚樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 敦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"JONES, Michael"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-01-30"}],"displaytype":"detail","filename":"tjsmbe-vannual59p400.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tjsmbe-vannual59p400","url":"https://iwate-u.repo.nii.ac.jp/record/15905/files/tjsmbe-vannual59p400.pdf"},"version_id":"221d7479-9341-4842-9dcd-81bc84ec2d54"}]},"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":"RGBカメラを用いた非接触酸素濃度推定技術に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RGBカメラを用いた非接触酸素濃度推定技術に関する研究"},{"subitem_title":"Study on Non-Contact Oxygen Saturation Estimation using an RGB Camera","subitem_title_language":"en"}]},"item_type_id":"16","owner":"19","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-01-30"},"publish_date":"2023-01-30","publish_status":"0","recid":"15905","relation_version_is_last":true,"title":["RGBカメラを用いた非接触酸素濃度推定技術に関する研究"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-05-15T12:40:25.879849+00:00"}
