The invention provides a near-infrared fluorescence detecting device. The near-infrared fluorescence detecting device includes: a white light source unit that irradiates white light to an observationtarget; a near-infrared excitation light source unit that emits near-infrared excitation light to the observation target; and a photodiagnostic assembly that is respectively conveyed by the The whitelight and the near-infrared excitation light reflect the reflected white light and the near-infrared fluorescence generated from the observation object; the multi-wavelength image processing unit detects the reflected white light and the near-infrared fluorescence received from the photo diagnostic assembly And respectively processed as a visible light reflected light image signal and a near infrared fluorescent image signal; a display unit that outputs the visible light reflected light image signal and the near infrared fluorescent image signal processed by the multi-wavelength image processing unit a combined composite image signal; the multi-wavelength image processing unit separates the detected reflected white light into red (R), green (G), and blue (B), and then detects the near infrared rays The pixel of the fluorescent image signal is composed of red (R), green (G), and blue (B), and the first color reflects the visible light reflected light image signal. Pixel embodiment can detect the near-infrared fluorescent image signal near the color reflected by a second color different from the first video signal is an infrared fluorescent image processing.
