PROBLEM TO BE SOLVED: To achieve the miniaturization of a subject observation system that can be used for a plurality of observations including a normal light observation and a special light observation, and can acquire an image of a desired wavelength band.SOLUTION: A subject observation system that converts the wavelength of a plurality of primary lights with different wavelengths emitted from a plurality of primary light sources respectively, irradiates a plurality of illumination lights including the lights whose wavelength is converted, to an observation object, and acquires an image of an illumination light irradiation region in the observation object by performing color separation by a plurality of color regions includes: a mode input part where a plurality of observation modes can be input light source means that, when a special light observation mode that highlights a specific observation object of the observation objects is input in the mode input part, turns on a plurality of primary light sources sequentially, and irradiates the illumination light to the observation object from an opening in the same place sequentially and image acquisition means that acquires a plurality of images each time the plurality of illumination lights are irradiated to the observation object respectively, and generates a special light observation image of the observation object on the basis of the plurality of images.COPYRIGHT: (C)2014,JPO&INPIT【課題】通常光観察や特殊光観察等の複数の観察に使用可能で、かつ所望の波長帯域の画像を得ることが可能な小型化を実現すること。【解決手段】複数の1次光源からそれぞれ射出された波長の異なる複数の1次光を波長変換し、当該波長変換した光を含む複数の照明光を観察対象に照射し、観察対象における照明光の照射領域の画像を複数の色領域により色分解して取得する被検体観察システムにおいて、複数の観察モードを入力可能なモード入力部と、モード入力部に観察対象のうち特定の観察対象を強調表示する特殊光観察モードが入力された場合、複数の1次光源を順次点灯して照明光を順次観察対象に対して同一箇所の開口から照射する光源手段と、複数の照明光をそれぞれ観察対象に照射する毎の複数の画像を取得し、当該複数の画像に基づいて観察対象の特殊光観察画像を生成する画像取得手段とを具備する。【選択図】図1
