The invention provides a light adjusting method and device for an endoscope light source, a light source assembly and an endoscope. The light adjusting method includes the steps that a first brightness value of a first image collected under a first driving current is acquired; whether a first difference value between the first brightness value and a target brightness value is within a preset rangeor not is judged; if not, a first current change quantity corresponding to the first difference value is inquired in a brightness-current change mapping table, and the driving current of the endoscope light source is adjusted to be a second driving current based on the first driving current and the first current change quantity; a second brightness value of a second image collected under the second driving current is acquired; whether a second difference value between the second brightness value and the target brightness value is within a preset range is judged; and if not, the first currentchange quantity corresponding to the first difference value in the brightness-current change mapping table is corrected, and the driving current of the endoscope light source is adjusted. Therefore, it can be guaranteed that the automatic light adjusting effect of the light source is optimal within the whole service period of all the light sources and each light source.
Description
technical field [0001] The invention relates to the technical field of endoscopes, in particular to a dimming method and device for an endoscope light source, a light source assembly and an endoscope. Background technique [0002] In the prior art, many medical devices such as endoscopes use cold light sources for illumination. In recent years, with the rapid development of LED light sources, many endoscopes use LED light sources as cold light sources for endoscopes. The role of the cold light source is to provide illumination for the front-end image acquisition of the mirror body. Since different imaging environments require different illumination brightness during actual operation, it is necessary to manually or automatically adjust the brightness of the LED light source. [0003] The current automatic dimming method is as follows: first obtain the brightness-current change mapping table of the LED light source through the preliminary experimental test, and then compare t...
