Patent ID: 8105232

Claim:
A fluorescent endoscopic device, comprising: an irradiation portion for irradiating illumination light and excitation light to a subject; a light receiving portion for receiving a reflection light image generated from the subject on the basis of the illumination light, and a first fluorescent image and a second fluorescent image in a wavelength band different from a wavelength band of the first fluorescent image, which are generated from the subject on the basis of the excitation light; a calculation portion for executing addition processing of the first fluorescent image and the second fluorescent image, division processing of the first fluorescent image and the second fluorescent image, logarithmic arithmetic processing of a result of the division processing, and processing of adding a result of the addition processing to a result of the logarithmic arithmetic processing or subtracting the result of the logarithmic arithmetic processing from the result of the addition processing; and an image creation portion for creating a fluorescent observation image on the basis of the reflection light image by means of the illumination light, the first fluorescent image, the second fluorescent image and a processing result of the calculation portion.
