PROBLEM TO BE SOLVED: To provide a fluorescent endoscope apparatus capable of acquiring a white light image and a plurality of kinds of fluorescent images at a high frame rate with simple configuration.SOLUTION: A fluorescent endoscope apparatus includes a light source part 10 time-divisionally emitting light in a plurality of kinds of irradiation patterns formed by combining two kinds of excitation light with light in a plurality of wavelength bands belonging to two kinds of wavelength regions out of RGB an imaging part 20 receiving reflected light and two kinds of fluorescent light and an image processing part 30 outputting the white light image and two kinds of fluorescent images. The imaging part has three kinds of imaging regions, and each receives two kinds of fluorescent light in the first imaging region, and receives reflected light in two kinds of wavelength bands and reflected light in a narrow band near the first imaging region in the second and third imaging regions. The image processing part outputs the first and second fluorescent images respectively using light receiving information on the two kinds of received fluorescent light, and outputs a pseudo white light image using light receiving information on the reflected light in the two kinds of wavelength bands and the reflected light in the narrow band near the first imaging region.COPYRIGHT: (C)2014,JPO&INPIT【課題】白色光画像と複数種類の蛍光画像とを簡易な構成で高フレームレートに取得可能な蛍光内視鏡装置の提供。【解決手段】RGBのうちの2種類の波長領域に属する複数波長帯域の光と2種類の励起光を組合せてなる、複数種類の照射パターンの光を時分割で出射する光源部10と、反射光と2種類の蛍光を受光する撮像部20と、白色光画像と2種類の蛍光画像を出力する画像処理部30とを有し、撮像部は3種類の撮像領域を有し、第1の撮像領域で2種類の蛍光を夫々受光するとともに、第2及び第3の撮像領域で2種類の波長帯域の反射光及び第1の撮像領域近傍の狭帯域の反射光を受光し、画像処理部は撮像部に受光された2種類の蛍光の受光情報を用いて第1及び第2の蛍光画像を夫々出力するとともに、2種類の波長帯域の反射光及び第1の撮像領域近傍の狭帯域の反射光の受光情報を用いて擬似的な白色光画像を出力する。【選択図】図3
