An image input apparatus that inputs an image of an object residing within a living body is disclosed. The image input apparatus includes a light source that irradiates near infrared light on the living body, a lens array arranged at a position facing the living body and including plural lenses each having a face with zero or negative power arranged at a side facing the living body and a face with positive power arranged at a side facing an image surface, an imaging unit arranged at the image surface side of the lens array that forms a compound-eye image corresponding to a collection of ommatidium images formed by the lenses of the lens array, and a reconstruction unit that reconstructs a single image from the compound-eye image using a parallax between the ommatidium images. The reconstructed single image is input as the image of the object.本發明揭露一種影像輸入裝置,其輸入一物件之影像,該物件存在一生物體之內。該影像輸入裝置包含:一光源,其將近紅外光照射於該生物體上;一透鏡陣列,其係設置於面向該生物體之一位置上並包含複數個透鏡,每一透鏡具有設置於面向該生物體之一側上具有零或負放大率之一面及設置於面向一影像表面之一側上具有正放大率之一面;一成像單元,其係設置於該透鏡陣列之該影像表面側上且係組構以形成一複眼影像,該複眼影像對應至由該透鏡陣列之該等透鏡所形成的小眼影像之集合;及一重建單元,其係組構以使用該等小眼影像間之一視差,從由該成像單元所形成之該複眼影像重建一單一影像。該經重建的單一影像係被輸入作為該物件之影像。
