Specifically, when the real-time difference value of a certain luminous flux detection point deviates from the preset difference value, the luminous flux detection point is defined as a preceding stage dead point, and the difference offset of the preceding stage dead point is compared with the difference offset of a subsequent stage dead point.
And S3, compensating the light flux of the mirror body by the light source according to the difference offset, and changing the light output level of the light source.
Specifically, when the differential offset of the subsequent point location is the same as that of the previous-stage point location, the light source compensates the luminous flux of the mirror body according to the differential offset of the previous-stage point location, and the light output quantity set by the light source is increased to a corresponding level.
When the difference offset of the subsequent point location is larger than that of the preceding-stage point location, the subsequent point location is defined as the rear-stage point location, so that the light source compensates the luminous flux of the mirror body according to the difference offset of the rear-stage point location, and the light output quantity set by the light source is increased to a corresponding level.
The endoscope luminous flux automatic detection compensation method can compensate the luminous flux of the endoscope body, change the light output level of the light source, keep the imaging picture brightness and the picture quality of the endoscope system unchanged, prolong the service life of the endoscope body, and improve the utilization rate of the light source and the energy consumption conversion ratio.
As shown in fig. 2, the above-mentioned method for automatically detecting and compensating the luminous flux of the endoscope can be implemented by an endoscope system including a light source, a light guide 20, an operating handle 30 and an insertion portion 40 connected in sequence, and at least two spot rings 10 capable of detecting the luminous flux are disposed between the light guide 20 and the insertion portion 40.

In this embodiment, the number of the photo resistors 12 is four, an included angle between two adjacent photo resistors 12 is 90 °, and the four photo resistors 12 are annularly arranged on the PCB 11.
