Title: IMAGING METHOD APPLICABLE TO ENDOSCOPE SYSTEM
Abstract:
Disclosed is an imaging method applicable to an endoscope system. The imaging method comprises: irradiating an observed part with irradiation light in a pre-set wave band, and collecting and obtaining a reflected light image of the observed part; and respectively multiplying a colour value matrix of each pixel point of the reflected light image by an image conversion matrix, so as to obtain an imaging result of the observed part, wherein the image conversion matrix is obtained by calculating a diagonal matrix of a weight coefficient, a diagonal element of the diagonal matrix of the weight coefficient is a weight coefficient of the light intensity of the collected reflected light image in each narrow-band wave band, and the pre-set wave band is equally divided into a pre-set number of narrow-band wave bands. In the imaging method, by irradiating an observed part with light in a pre-set wave band to obtain a reflected light image capable of distinguishing a vascular region and a non-vascular region, and carrying out spectral filtering processing on the image, a characteristic spectrum of an image of each region can be enhanced, thereby improving the difference between the vascular region and the non-vascular region, improving the image contrast, and improving the imaging quality.
