Fluorescence endoscopy and endoscopic device therefor

摘要

A fluorescence endoscopy and an endoscopic device therefor, wherein, to an object to be examined containing a fluorescent substance, light rays in a plurality of wavelength ranges whose degrees of exciting the fluorescent substance are different from one another and which can constitute a color images are sequentially irradiated; images of the object are obtained by the respective wavelength ranges; a color image of the object is constituted using the images obtained by the respective wavelength ranges and information based on fluorescence emitted by the fluorescent substance, is obtained using at least an image obtained by a wavelength whose degree of exciting the fluorescent substance is largest out of the images obtained by the respective wavelength ranges.
