Polarized light endoscope device

Abstract

A polarized light endoscope device comprises an optical prism, an RGB image sensor, a polarized light image sensor and an image processor, the optical prism divides one light beam output by an optical lens into two light beams, one light beam is output to the RGB image sensor, and the other light beam is output to the polarized light image sensor; the RGB image sensor collects RGB optical signals and converts the RGB optical signals into RGB pixel data; the polarized light image sensor collects polarized light signals and converts the polarized light signals into polarization information pixel data; and the image processor synchronously performs image processing on the RGB pixel data and sharpening processing on the polarization information pixel data, and outputs and displays the obtained RGB image and the polarization information image, so that when blood, tissue crumbs, fog and the like appear in an operation environment, the problem that the output image of the endoscope device is not clear is solved through sharpening processing on the polarization information pixel data.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a polarized light endoscope device. Background technique [0002] Endoscope is a medical electronic optical instrument that can be inserted into the human body cavity and viscera cavity for direct observation, diagnosis and treatment. Perform optical imaging, then send the optical imaging to the image processing host, and finally output the image-processed observation image on the display screen for observation and diagnosis by doctors. [0003] At present, endoscopes mainly include ultra-high-definition 4K endoscopes, three-chip endoscopes, fluorescent endoscopes, narrow-band light endoscopes, 3D endoscopes, etc. These endoscopes have very good performance in their respective fields. function and performance. Among them, the 4K endoscope has ultra-high-definition resolution, and the details are well restored; the three-chip endoscope has three image sensors to collect a mon...

Problems solved by technology

[0004] Although the functions and performance of the above endoscopes are very good, they cannot output clear imaging in the surgical environment with bloody water, turbid water, small tissue debris, and fog. Unclear imaging will make the doctor suffer during the operation. Interference, sometimes it is necessary to clean up the interfering environment (bloody water, turbid water, tissue scraps, fog) before performing surgery, resulting in low surgical efficiency
