Endoscope imaging system, light source control method thereof, and computer readable storage medium
An endoscope imaging system, and a control method for a light source of an endoscope imaging system, are disclosed. After a function key is triggered, the image processing unit controls the light source unit to perform a first function, and controls the endoscope imaging system to perform a second function which corresponds to the function key. Alternatively, the image processing unit controls the light source unit to perform a first function, after the function key is triggered; and controls the endoscope imaging system to perform a second function which corresponds to the function key, after the function key is re-triggered. This disclosure provides another completely different way to control the light source unit to perform the first function, so as to achieve functional linkage of various units in the endoscope imaging system, simplify operation steps, and improve surgical efficiency.
