[0003] However, this adjustment method is limited by the output frame rate of the imaging component at the head end of the lens body. When the lens body moves rapidly or the lens body moves rapidly together with the cavity, the stability of the image brightness is not good, resulting in flickering image brightness. , affects the observation of key image information, and is not friendly to human eyes

The invention discloses a control method for the light-emitting quantity of an endoscope and an endoscope system. The control method for the light emitting amount of the endoscope comprises the following steps: 1), obtaining light emitting amount change coefficients of an endoscope body in different motion states; 2) comparing a current image acquired by the endoscope body with a preset image to obtain an initial light-emitting quantity variable quantity; (3) obtaining the motion state of the endoscope body, acting the light-emitting quantity change coefficient in the motion state on the initial light-emitting quantity variable quantity, and thus obtaining the final light-emitting quantity variable quantity; and 4) enabling a light source to output the final light-emitting quantity according to the final light-emitting quantity variable quantity. According to the control method for the light-emitting quantity of the endoscope, the light-emitting quantity variable quantity coefficient acts on the initial light-emitting quantity variation, and the light-emitting quantity variable quantity is combined with the motion state, so that the current image brightness can be closer to the target brightness more quickly.
Description
technical field [0001] The invention relates to the field of endoscopes, in particular to a method for controlling the amount of light emitted by the endoscope and an endoscope system. Background technique [0002] The endoscope in the prior art obtains the image of the scene through the imaging component at the head end of the lens body, and calculates whether the brightness of each frame of the image is consistent with the preset image brightness. If not, the light output of the endoscope light source is changed to achieve the image Brightness is maintained for the purpose of stabilization. [0003] However, this adjustment method is limited by the output frame rate of the imaging component at the head end of the lens body. When the lens body moves rapidly or the lens body moves rapidly together with the cavity, the stability of the image brightness is not good, resulting in the image brightness flickering , affects the observation of key image information, and is not fri...
