PROBLEM TO BE SOLVED: To provide an analyzer capable of suppressing reduction of a frame rate of a picked up image, and furthermore capable of performing spectroscopic analysis.SOLUTION: An analyzer is comprised of: a light source device； a wavelength selection part for alternatively taking out a first special light and a second special light from a light emitted from the light source device； an imaging device having an RGB color filter； and a signal processing part. In the configuration, the first special light includes a light of a first wavelength region passing through a G filter, the second special light includes a light of a second wavelength region passing through the G filter and different from the first wavelength region, and at least one of the first special light and the second special light includes a light passing through an R filter, and at least one of the first special light and second special light includes a light passing through a B filter. The signal processing part calculates an index indicating a feature quantity of a biological tissue based on a pixel signal according to the light of the first wavelength region, and a pixel signal according to the light of the second wavelength region, and based on a pixel signal according to a light passing through the RGB color filter, generates a color picked-up image.SELECTED DRAWING: Figure 6【課題】撮影画像のフレームレートの低下を抑制しつつ、分光学的分析が可能な分析装置を提供する。【解決手段】分析装置を、光源装置と、光源装置から射出された光から第１特殊光と第２特殊光を択一的に取り出す波長選択部と、ＲＧＢカラーフィルタを備えた撮像素子と、信号処理部と、から構成する。この構成において、第１特殊光はＧフィルタを通過する第１波長域の光を含み、第２特殊光は、Ｇフィルタを通過し、第１波長域とは異なる第２波長域の光を含み、第１特殊光と第２特殊光の少なくとも一方はＲフィルタを通過する光を含み、第１特殊光と第２特殊光の少なくとも一方はＢフィルタを通過する光を含む。また、信号処理部は、第１波長域の光に応じた画素信号及び第２波長域の光に応じた画素信号に基づいて、生体組織の特徴量を示す指標を算出し、ＲＧＢカラーフィルタを通過する光に応じた画素信号に基づいて、カラー撮影画像を生成する。【選択図】図６
