The present invention provides a dimming method and device for an endoscope light source, a light source assembly and an endoscope, comprising: acquiring a first brightness value of a first image collected under a first driving current; judging the first brightness value Whether the first difference between the target brightness value is within the preset range; if not, query the first current variation corresponding to the first difference in the brightness-current variation mapping table, and based on the first driving current and the first current variation, adjust the driving current of the endoscope light source to be the second driving current; obtain the second brightness value of the second image collected under the second driving current; judge the difference between the second brightness value and the target brightness value Whether the second difference between them is within the preset range; if not, correct the first current variation corresponding to the first difference in the brightness-current variation mapping table, and adjust the driving current of the endoscope light source, so that Ensure that all light sources and each light source have the best automatic dimming effect during the entire service life of each light source.
Description
Technical field [0001] The present invention relates to the field of endoscopic techniques, and more particularly to a dimming method, apparatus, a light source assembly, and an endoscope of an endoscope light source. Background technique [0002] In the prior art, many medical devices such as endoscopes are illuminated with cold light sources. In recent years, with the rapid development of the LED source, many endoscopes use the LED light source as a cold light source of endoscopy. The action of the cold light source is to provide illumination for the front end image acquisition of the mirror. Since different imaging environments in the actual operation require different illumination brightness, it is necessary to manually or automatically adjust the brightness of the LED light source. [0003] The automatic dimming method currently adopted is: first obtain the brightness-current change mapping table of the LED light source through the previous experiment test, and then compare ...
