PROBLEM TO BE SOLVED: To provide an organism image processor and an organism image processing method capable of acquiring a clear organism image.SOLUTION: The organism image processor includes: an imaging unit that picks up a first image of an organism which is irradiated with a beam of light of a first wavelength, and a second image of the organism which is irradiated with a beam of light of a second wavelength shorter than the first wavelength； and a calculation part that calculates a third image obtained by subtracting the second image whose brightness is reduced from the first image.SELECTED DRAWING: Figure 1【課題】生体画像処理装置及び生体画像処理方法において、明瞭な生体画像を取得することを目的とする。【解決手段】生体画像処理装置は、第１の波長の光を照射された生体の第１の画像と、前記第１の波長より短い第２の波長の光を照射された前記生体の第２の画像とを撮影する撮影装置と、前記第１の画像から、前記第２の画像の輝度を減衰させた画像を差し引いた第３の画像を求める演算部とを備える。【選択図】図１
