Fluorescence endoscope system and control method thereof

A fluorescence endoscope system, comprising:

• a light source module having a first light guide configured to guide illumination beams emitted by the light source module, wherein the illumination beams comprise a first illumination beam corresponding to a white-light mode and a second illumination beam corresponding to a fluorescence mode;
• a camera module having an endoscope and an operation portion wherein the endoscope and the operation portion are coupled to each other, the endoscope is configured to propagate the illumination beams guided by the first light guide and reflected beams formed after the illumination beams are irradiated to an object, and the operation portion is configured to receive the reflected beams and convert the reflected beams into video data;
• a main control module having a control unit and an image processing unit, wherein the control unit is configured to control the light source module to emit the first illumination beam or the second illumination beam, and the image processing unit is configured to process the video data frame by frame;
• and
• a display module configured to play the video data processed by the image processing unit;
• wherein the operation portion comprises a hand-held main body and a first button arranged on the hand-held main body, wherein the operation portion is configured to generate a first control signal after the first button is triggered, the operation portion transmits the first control signal to the image processing unit, and the first control signal is allowed for controlling the light source module to emit the first illumination beam or the second illumination beam to switch between the white-light mode and the fluorescence mode.
