Abstract:
1. An endoscopic fluorescence imaging apparatus comprising: a fluorescence image obtaining means for irradiating a target subject with an excitation light and obtaining two fluorescence image data, each formed of fluorescent light of a mutually different wavelength band with a filter having at least two individual bandpass filters filtering the mutually different wavelength band, based on the fluorescent light intensity emitted from the target subject upon the irradiation thereof by the excitation light, a gain computing means for computing, based on statistical quantity of either one of said two fluorescence image data, a gain that said two fluorescence image data are to be multiplied by, a multiplying means for multiplying said two fluorescence image data by said gain and obtaining two multiplied fluorescence image data, an image forming means for forming, based on said two multiplied fluorescence image data, a pseudo color image data representing a pseudo color image reflecting the tissue state of the target subject, and an image display means for displaying said pseudo color image.
