Endoscope brightness automatic regulation device and regulation control method thereof

Abstract

The invention relates to an endoscope brightness automatic regulation device, which comprises an image processing module, a light path baffle plate and a baffle plate driving motor, wherein the input end of the image processing module is connected with the output end of an endoscope, the output end of the image processing module is connected with the input end of the baffle plate driving motor, the light path baffle plate is arranged in the light path, and a bearing of the baffle plate driving motor is connected with a transmission shaft of the light path baffle plate and drives a baffle plate to move in the light path for regulating the brightness of cold light sources received by a light source incidence opening of the endoscope. The invention also relates to a method for realizing the automatic regulation control of the endoscope brightness on the basis of the device. When the endoscope brightness automatic regulation device and the regulation control method are adopted, the baffle plate driving motor is controlled to regulate the baffle plate on the basis of analysis of the endoscope output image brightness, so the cold light source brightness received by the endoscope is changed, and the optimum imaging effect of the endoscope is ensured. The endoscope brightness automatic regulation device has a simple structure, the regulation control method of the endoscope brightness automatic regulation device is simple and convenient, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to the technical field of endoscope control devices, in particular to an endoscope brightness automatic adjustment device and an adjustment control method thereof. Background technique [0002] Endoscope is a commonly used medical device, which is widely used in various minimally invasive operations. A common endoscope consists of a head end, a bending part, a main hose, an operating part, a miniature photocoupler (which may include CCD and CMOS, which are all suitable), an image output interface and a light guide plug. Wherein the head end comprises a micro-convex objective lens, an image transmission fiber beginning, and a light-transmission optical fiber end, and the micro-convex objective lens is arranged on the front end of the head end for receiving reflected light from the object surface; the bending part is the head end and the main body. The middle part of the mechanica...
