IMAGE PROCESSING SYSTEM, FLUORESCENT ENDOSCOPIC ILLUMINATED IMAGING APPARATUS AND IMAGING METHOD

An imaging method of a fluorescent image performs image processing before generating colored-fluorescent images, including steps: respectively imaging the red, green and blue lights of the white light on three monochromatic sensors under the precondition that the software processing speed is not affected; imaging the near infrared fluorescent light on one of the monochromatic sensors; determining whether the sensor used to receive the near infrared fluorescent light receives the fluorescent signal; calculating the light intensity received by the sensor receiving the fluorescent signal and the light intensities received by the other two sensors; automatically adjusting the projection intensity of the white light source and/or the excitation light source according to the difference of the intensities of the two types of light signals, whereby a closed-loop system is formed to simultaneously present the colored-florescent images on a picture with the best contrast.
