In URA coded aperture camera, the pinhole is replaced by multi-pinhole arrays arranged in m-sequences. Since the URA camera can view the object with a large solid angle, it can also provide some tomographic resolution for three-dimensional objects. But a reconstructed image is blurred by defocus artifact. In this paper, we propose a new iterative algorithm to remove the defocus artifact. We show that the reconstructed image can be improved by using the proposed iterative algorithm.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/1961"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0389-102X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025048X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8\u7d00\u8981"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueNumber": "58", "bibliographicPageEnd": "78", "bibliographicPageStart": "73"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "No58p73.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2001979/files/No58p73.pdf"}, "version_id": "4edf8fb4-23ac-4f40-8cf9-d9790274b98e"}]}, "item_title": "\u53cd\u5fa9\u6cd5\u306b\u3088\u308b\uff35\uff32\uff21\u30c8\u30e2\u30b0\u30e9\u30d5\u30a3\u30c3\u30af\u30a4\u30e1\u30fc\u30b8\u306e\u753b\u8cea\u6539\u5584", "item_type_id": "15", "owner": "1", "path": ["1642837875711", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/1961", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-09-16"}, "publish_date": "2007-09-16", "publish_status": "0", "recid": "2001979", "relation": {}, "relation_version_is_last": true, "title": ["\u53cd\u5fa9\u6cd5\u306b\u3088\u308b\uff35\uff32\uff21\u30c8\u30e2\u30b0\u30e9\u30d5\u30a3\u30c3\u30af\u30a4\u30e1\u30fc\u30b8\u306e\u753b\u8cea\u6539\u5584"], "weko_shared_id": -1}
