Problems solved by technology

However, in the existing technologies, some use spectroscopic imaging technology related to wavelength and spatial position, and use multi-block movement to select images of different wavelengths for display and imaging, but this imaging method has low energy utilization of light and high imaging resolution. Not high, and the optical path design is very cumbersome, it is difficult to meet the development needs of high-definition imaging of endoscopes

Description

technical field [0001] The invention relates to the technical field of medical electronic endoscope imaging inspection, in particular to a multispectral endoscope imaging device. Background technique [0002] An endoscopic imaging device for surgery and other medical purposes generally includes an endoscopic body, a light source, and an image processing unit (CCU). The body of the endoscope is partially inserted into the human body, providing the optical path carrier and instrument channel, the light source mainly provides internal illumination, and the image processing unit (CCU) is a key component of image processing. The imaging signal obtained by the imaging device is processed by the predetermined image processing technology of the image processing unit (CCU) into an imaging image displayed on the monitor. Thereby, the operator can observe the inside of the body by viewing the image displayed on the monitor. [0003] The endoscope imaging device is used for observing ...
