To provide an imaging device for capturing infrared images capable of accurately counting, even by computer, etc., "minute particles that have not been finely pulverized or mashed" by irradiating infrared light during image capture on to an artificial food mass that is the imaging subject as well as capturing using the imaging device an image of infrared light that passes through the artificial food mass. An imaging device for capturing images of an artificial food mass, which is the imaging subject and contains light-permeable fine particles, on to a substrate with infrared light blocking properties. Said imaging device comprises an image capture means for capturing images of the imaging subject from one direction and an infrared light source that irradiates infrared light on to the imaging subject from another side of the imaging subject. The image capture means has a visible light elimination means to prevent visible light being received and captures images of the imaging subject while infrared light is being irradiated on the imaging subject by the infrared light source.本發明之目的在於提供一種用以對紅外影像進行攝影之攝影裝置,其藉由在攝影時對作為被攝影對象之人工食物塊照射紅外光,並且藉由攝影裝置攝影穿透人工食物塊之紅外光,即便藉由電腦等亦可精度良好地進行「未被微細地粉碎、磨碎之微粒子」之計數。本發明之攝影裝置係用以於具有遮蔽紅外光之性質之基材上,對包含具有光穿透性之微粒子之人工食物塊即被攝影對象進行攝影,其具備有:攝影手段,其用以對被攝影對象自一側進行攝影;及紅外光源,其自被攝影對象之另一側,對被攝影對象照射紅外光;且攝影手段具有用以不接收可見光之可見光除去手段,於藉由紅外光源對被攝影對象照射紅外光之狀態下,藉由攝影手段對被攝影對象進行攝影。10...影像攝影系統12...被攝影對象14...顯微鏡玻片20...攝影裝置22...攝影手段24...紅外光源26...可見光切斷濾波器28...擴散濾波器30...保持機構32...支撐軸34...底座部36...電纜40...電腦42...記憶裝置44...運算裝置
