Problems solved by technology

[0004] However, in the process of realizing synchronous imaging or fusion imaging of multiple imaging modes, the inventors found that: since the wavelength band of the fluorescence signal collected in the fluorescence imaging mode is usually different from the green light band in the illumination band of the narrowband imaging / white light imaging mode Therefore, the green fluorescent signal and the green illumination light signal cannot be effectively separated; and if the signal is separated by time-sharing illumination, there will be motion artifacts in the obtained adjacent frame tissue images, and it will also cause processor The frame rate of the output video drops, and there is a freeze phenomenon, which is not conducive to improving the image quality

Abstract

The invention discloses an electronic endoscope which comprises a light source device, a photographic device and a processor. The light source device is used for emitting an illumination light and anexciting light for an object to be photographed; the illumination light comprises a green narrow-band light; the exciting light is the light for exciting the object to be photographed to produce greenfluorescence; the photographic device comprises a first filter, a second filter and an image sensor; and the processor is used for generating a fluorescence image based on a fluorescence image signal, and / or generating a green narrow-band light image based on a green narrow-band light image signal, and / or generating a blending image based on the fluorescence image signal and the green narrow-bandlight image signal. According to the electronic endoscope provided by the invention, a green fluorescence signal and a green illumination light signal can be separated, so that the fluorescence imageand the green light image are imaged simultaneously.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an electronic endoscope. Background technique [0002] An electronic endoscope is a medical electronic optical instrument that integrates optical, mechanical, and electrical technologies. The cable / optical cable transmits the received image signal to the image processing system, and finally outputs the processed image on the monitor for observation. [0003] Currently, the imaging modes of electronic endoscopes mainly include white light imaging mode, narrowband imaging mode, fluorescence imaging mode and monochromatic light imaging mode, etc. These imaging modes have their own advantages and disadvantages. Therefore, in order to distinguish normal tissue from diseased tissue more accurately and quickly, two or more of these modes can be used for simultaneous imaging or fusion imaging. [0004] However, in the process of realizing synchronous imaging or fusion imaging o...
