However, the computational complexity is very large, and it is not realistic method. Meanwhile, Fresnel CGH made by two dimensional Fourier transforms of each images sampled at a direction of depth is proposed. By this method, the computational complexity is proportional to the sampling number on depth. Therefore, only an object with limited information about the depth can be recorded by this method. In this paper, we proposed novel method for fast calculation of Fresnel CGH. It is to use two dimensional projected image holding on the depth information of the object, instead of three dimensional object, in the equation of Fresnel diffraction. Proposed Fresnel CGH can reconstruct an three dimensional object with continuous depth information. Some experimental results are also presented."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001204523617538","@type":"Researcher","foaf:name":[{"@language":"ja","@value":"森 邦彦"},{"@language":"en","@value":"Mori Kunihiko"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Faculty of Engineering, Kagoshima University"},{"@language":"ja","@value":"鹿児島大学工学部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001204424871936","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000237687369"}],"foaf:name":[{"@language":"ja","@value":"西 省吾"},{"@language":"en","@value":"Nishi Syougo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Faculty of Engineering, Kagoshima University"},{"@language":"ja","@value":"鹿児島大学工学部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001204523617539","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000237687368"}],"foaf:name":[{"@language":"ja","@value":"河原田 健"},{"@language":"en","@value":"Kawaharada Kenn"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Faculty of Engineering, Kagoshima University"},{"@language":"ja","@value":"鹿児島大学工学部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001204523617536","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000005324009"}],"foaf:name":[{"@language":"ja","@value":"居細工 成健"},{"@language":"en","@value":"Izaiku Noritake"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Faculty of Engineering, Kagoshima University"},{"@language":"ja","@value":"鹿児島大学工学部"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"13426893"},{"@type":"EISSN","@value":"24241970"},{"@type":"NCID","@value":"AN1059086X"}],"prism:publicationName":[{"@language":"ja","@value":"映像情報メディア学会技術報告"},{"@language":"en","@value":"ITE Technical Report"},{"@language":"ja","@value":"映情学技報"}],"dc:publisher":[{"@language":"en","@value":"The Institute of Image Information and Television Engineers"},{"@language":"ja","@value":"一般社団法人 映像情報メディア学会"}],"prism:publicationDate":"1997","prism:volume":"21.66","prism:number":"0","prism:startingPage":"17","prism:endingPage":"20"},"availableAt":"1997","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390001204523380352","@type":"Article","relationType":["isCitedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"21世紀に期待する映像表現研究と作品製作"},{"@language":"en","@value":"Artistic Image Research and Image Creation Expecting for 21 Century"},{"@value":"基調講演 21世紀に期待する映像表現研究と作品制作"},{"@language":"ja-Kana","@value":"キチョウ コウエン 21セイキ ニ キタイ スル エイゾウ ヒョウゲン ケンキュウ ト サクヒン セイサク"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282680074069632","@type":"Article","relationType":["isCitedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"The Recent Progress of Image Information and Television. 4.
