PROBLEM TO BE SOLVED: To obtain blood vessel and blood-related information from a bulbar conjunctiva so as to prevent and early find lifestyle-related diseases such as a vascular complication.SOLUTION: This circulatory system diagnostic system includes: a photographing means capable of photographing an eye close to the eye a magnification means magnifying the white part of the eye photographed by the photographing means a blood vessel extraction means extracting a blood vessel from an image magnified by the magnification means a comparison means comparing the blood vessel extracted by the blood vessel extraction means with a previously recorded blood vessel pattern, or a comparison arithmetic means calculating a distance by which a blood cell or the like has moved between the images to obtain a blood flow velocity and a decision means deciding an abnormal blood vessel pattern or an abnormal blood flow state obtained as the result of the comparison by the comparison means or the like.COPYRIGHT: (C)2013,JPO&INPIT【課題】血管合併症等の生活習慣病の予防と早期発見の為に、眼球結膜から、血管、血液関連情報を得る。【解決手段】眼を近接して撮影可能とする撮影手段、前記撮影手段で撮影した白目を拡大する拡大手段、前記拡大手段で拡大された画像から血管を抽出する血管抽出手段、前記血管抽出手段で抽出された血管と、予め記録された血管パターンとを比較する比較手段、又は、画像間での血球等の動いた距離を算出して血流速度をもとめる比較演算手段、前記比較手段等で比較され、異常血管パターン、異常血流状態を判定する判定手段よりなる。【選択図】図1
