As is apparent from the above description, an embodiment of the present invention provides an endoscopic imaging system including a light source device 1, an endoscope, and a processing device 3; the invention adopts at least three light sources with different wavelengths in the light source device 1 to illuminate the area to be detected for the first time, and acquires initial image data of the area to be detected through the image acquisition module 2 of the endoscope, and the obtained initial image data can be characterized as blood vessels with different depths, surface textures of the mucous membrane tissues and the like due to different penetration depths of the light sources with different wavelengths to the mucous membrane layer tissues; the processing device 3 processes and analyzes the initial image data to obtain information such as definition, quantity and color difference of characteristics such as blood vessels and surface textures, and adjusts the luminous brightness of different light sources in the light source device 1 based on the information, so that the spectral proportion of the light sources can be automatically adjusted according to the characteristic information of different focuses; after the adjusted light source is adopted to illuminate the region to be detected for the second time, the image acquisition module 2 can acquire target image data of the region to be detected, the processing device 3 obtains a target image based on the target image data, the imaging effect of the target image is better than that of an initial image obtained by the last illumination, and more tissue details of the region to be detected can be observed, so that efficient endoscopic imaging is realized.
Optionally, in another embodiment of the present invention, the light source device 1 in the above-mentioned endoscopic imaging system is further described, referring to fig. 2, fig. 2 is a schematic structural diagram of the light source device in the endoscopic imaging system according to the embodiment of the present invention, and in conjunction with fig. 2, the light source includes: a white light source 11, a blue light source 12 with a wavelength ranging from 420nm to 480nm, and a blue-violet light source 13 with a wavelength ranging from 390nm to 420 nm.
Specifically, in the embodiment of the present invention, because the surface blood vessel absorbs the blue-violet light source 13 highly, the blue-violet light source 13 illuminates the region to be detected, and the image acquisition module 2 can acquire the image data of the surface blood vessel; because the wavelength of the blue-violet light source 13 is shorter, the capability of the blue-violet light source 13 for insufficient penetration depth of the mucosal tissue is required to be used for illuminating the region to be detected, so that the image acquisition module 2 can acquire the image data of the middle-deep blood vessel; in the embodiment of the present invention, the white light source 11 may be used to improve the exposure of the light source device 1 to adjust the overall brightness of the light source device 1.
The light source device 1 further includes: a total reflection mirror 14, a first long-pass filter 15, and a second long-pass filter 16; the total reflection mirror 14 is used for reflecting the white light source 11 to the first long-pass filter 15; the first long-pass filter 15 is configured to couple the white light source 11 and the blue light source 12 to the second long-pass filter 16; the second long-pass filter 16 is configured to couple the white light source 11, the blue light source 12, and the blue-violet light source 13 into an illumination beam, and the light source device 1 is configured to illuminate the area to be detected based on the illumination beam.

Specifically, in the embodiment of the present invention, as shown in fig. 2, the light emitted from the white light source 11 is reflected to the first long-pass filter 15 through the total reflection mirror 14, and since the first long-pass filter 15 can transmit the light with longer wavelength and reflect the light with shorter wavelength, the white light reflected to the first long-pass filter 15 by the total reflection mirror 14 can transmit at the first long-pass filter 15, the blue light emitted to the first long-pass filter 15 by the blue light source 12 is reflected by the first long-pass filter 15, and the first long-pass filter 15 couples the white light and the blue light into a beam of light and then transmits the beam of light to the second long-pass filter 16; similarly, the second long-pass filter 16 may transmit white light and blue light, and reflect blue-violet light emitted from the blue-violet light source 13 toward the second long-pass filter 16, so that the light source device 1 finally illuminates the area to be detected as a beam of illumination light after the white light, the blue light and the blue-violet light are optically coupled through the second long-pass filter 16.
