Problems solved by technology

However, the narrow-band light of different bands is irradiated on the surface of the measured tissue sequentially in time sequence. If the target moves during the shooting process, the position where the narrow-band light of different bands irradiates will change, resulting in distortion of the narrow-band image.

Abstract

The invention provides an enhanced display narrow band imaging endoscopy system. The system comprises an image collection device, an image processing device and an image display device. The image collection device comprises multiple cameras, and the image processing device comprises an image collection module and a narrow band image processing module. According to the enhanced display narrow bandimaging endoscopy system, the cameras are used for collecting narrow band images and white light images, the white light images pass through the image collection module and then are directly output tothe image display device to be displayed in a normal mode, and the narrow band images are processed by the narrow band processing module and displayed in a narrow band mode through the image displaydevice. The narrow band mode display can improve the image quality of narrow band imaging and enhance the blood vessel image information. The invention further provides an imaging method of the enhanced display narrow band imaging endoscopy system.

Description

technical field [0001] The invention relates to the technical field of endoscope imaging, in particular to an enhanced display narrow-band imaging endoscope system and an imaging method thereof. Background technique [0002] The illumination source of the endoscope is generally a white LED cold light source, which can only collect relatively macroscopic tissue images, but it is difficult to observe the superficial micro blood vessels of the tissue. However, hemoglobin in the blood has different absorption levels for specific narrow-band spectra. Narrow-band imaging endoscopes use this feature to obtain images of superficial microvessels in the human body. [0003] Traditional electronic endoscopes use broadband white light sources such as xenon lamps or LED cold light sources as illumination light. Currently, commonly used narrow-band imaging endoscopes add a narrow-band filter after the white light source to filter the broadband white light, leaving only the peak wavelength...
