Claim One:
1. A fluorescence endoscope apparatus comprising a light source unit emitting light in a combination of light in at least one of plural types of wavelength bands in two types of wavelength ranges of RGB and one of two types of exciting light, with plural types of emitting patterns and in a time division, an image pickup unit receiving light reflected by an object to be observed and two types of fluorescence emitted by two types of fluorescent substances that exist in the object by radiating to the object each light emitted from the light source unit in a time division, and an image-processing unit outputting a white light image and two types of fluorescence images with the light that is received by the image pickup unit, the image pickup unit having three types of image-pickup ranges, receiving the two types of fluorescence in a first image-pickup range, and receiving reflected light in two types of wavelength bands and reflected light in a narrow wavelength band in a vicinity of the first image-pickup range in a second image-pickup range and in a third image-pickup range, and the image-processing unit outputting a first fluorescence image and a second fluorescence image with information on the two types of fluorescence which are received by the image pickup unit and outputting a pseudo white light image with information on the reflected light in the two types of the wavelength bands which is received by the image pickup unit and with information on the reflected light in the narrow band in the vicinity of the first image-pickup range which is received by the image pickup unit.
