Method for converting endoscope images to narrow band images

A method for converting endoscope images to narrow band images, comprising:

• acquiring a reference image data of a reference object by a first image capturing unit and acquiring a narrow-band reference image data of said reference object by a second image capturing unit, and transmitting said reference image data and said narrow-band reference image data to an operational device by said first image capturing unit and said second image capturing unit;
• executing data operations according to said reference image data and said narrow-band reference image data to obtain hyperspectral reference image data, a narrow-band conversion parameter, and a first light-source parameter by said operational device;
• generating narrow-band simulated image data according to said hyperspectral reference image data, said narrow-band reference image data, and said first light-source parameter by said operational device;
• comparing said narrow-band reference image data and said narrow-band simulated image data to obtain chromatic aberration data by said operational device;
• executing data operations according to said narrow-band simulated image data and said first light-source parameter to obtain a second light-source parameter by said operational device;
• acquiring an input image data of an object under detect and transmitting said input image data to said operational device by said first image capturing unit;
• and
• generating narrow-band image data of said object under detect according to said input image data, said narrow-band conversion parameter, and said second light-source parameter by said operational device.
