With the device and the method where it records and plays back the picture of the inspection object and, decreasing optical stress, recording the picture of the inspection object with, to become independent a less adjustment labor and, furthermore, from brightness substantially, to the metabolism action of the eye and the examination on the spectrum of minute circulation and be suited same as functional picture conversion high-level, to be conformity possible in medical investigation, while being simple and feasibility the modification of very economic structure making possible, complicated secondary image information it designates that the secondary picture which is made offer possible is formed as purpose. The illumination system includes one which possesses the expedient which illuminates the inspection object simultaneously at least depending upon with one where each one conforms to the color channel of the picture formation record system standard wave length territory and one information wave length territory at least, illumination optical path at least. At least, one standard wave length territory, is almost constant at least in regard to medical-related information, on the one hand, at least one information wave length territory, is provided in order to detect medical-related information. This method of relating to this invention mixing the appraisal window of the picture which is recorded simultaneously, or the picture value of the individual picture image point as it forms the secondary picture and picture series, is mixed in order to form the functional picture forms the dynamic characteristic value which is dissected spatially.検査対象の画像を記録及び再生する装置及び方法では、光ストレスを低減してより少ない調整労力で検査対象の画像を記録することと、さらに、輝度から実質的に独立し、機能的画像化と同様に眼の代謝作用及び微小循環のスペクトル上の検討にも高度に適し、医学的な調査に適合可能であり、簡単で実行可能な非常に経済的な構造の変更をも可能としつつ、複雑な二次画像情報を提供可能とする二次画像を生成することを目的とする。照明システムは、それぞれが画像生成記録システムのカラーチャネルに適合する少なくとも1つの基準波長領域と少なくとも1つの情報波長領域とにより、同時に検査対象を照明する手段を有する少なくとも1つの照明光路を含む。少なくとも1つの基準波長領域が、医学関連情報に関して少なくともほぼ不
