The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference Figure 1-4 , an ultra-thin electronic choledochoscope system with treatment channels and data interaction, including an ultra-thin straight needle lens 1, a camera system control host 2, a cold light source lighting system 3 and a display screen 4;

[0030] The ultra-fine straight pin lens 1 is an optical lens. The total length of the ultra-fine straight pin lens 1 is 434 mm, the diameter of the lens body is 3 mm, and the ultra-fine straight pin lens 1 is connected to the camera system control host 2 and the cold light source lighting system 3 through wires; the ultra-fine straight pin lens 1 includes a front objective lens end 5, a middle lens body 6, a rear cold light source harness interface 7, a grip handle 8, and a rear camera host harness 9;

[0031] The camera system control host 2 is composed of a photoelectric conversion image acquisition module, a digital image processing module, a display control module, an image output module, a storage module interface and a communication module; the digital image processing module is used to perform real-time image processing on the video stream acquired by the front-end image sensor, and to realize image visualization by using a white light imaging image enhancement algorithm through the white light image obtained under white light conditions; the digital image processing module is composed of a main control board and multiple small boards, and the main control board cooperates with the embedded embedded program to mainly complete image signal processing, data conversion, image output, image storage, receiving display control signals and communication networking.

[0032] The photoelectric conversion image acquisition module contains a PCB board embedded with a CMOS image sensor. The CMOS image sensor and peripheral circuits complete the conversion of optical signals into electrical signals. The display control module consists of a control board and a touch screen. After the control board receives the function instructions triggered on the touch screen, the control board communicates with the digital image processing module, and the digital image processing module completes the corresponding functions triggered on the touch screen. The touch screen can realize the control of the camera screen, mainly including screen freezing, recording, taking pictures, playback, screen zooming in, zooming out and white balance.

[0033] The video signal processed by the image processing module is output to the display screen through the image output module, which supports HDMI2.0 and supports a maximum output of 1080P@60fps. The image storage module interface includes support for external USB storage, and the interface is compatible with USB3.0 and USB2.0. The recorded video and photos are stored in an external USB storage device. The communication module is a Wifi module, which supports the mainstream 2.4G / 5G frequency bands and has the characteristics of low latency and strong anti-interference. The communication module is connected to the local area network, and the camera image can be transmitted to the digital intelligent operating room IMUMS core platform in real time. Doctors can observe and guide the operation remotely and store the image data in real time.

[0034] The cold light source lighting system is mainly composed of a cold light source host, a light guide and a power cord. It uses a high-ratio LED light source and has advanced technologies such as aspherical optical technology, current dimming, brightness adjustment and overheating protection. The color temperature range is 3000K-7000k, and the brightness is adjustable from 1 to 20 levels. The light source status can be viewed in real time, including the use time, light source temperature, and light source power. The system mainly provides a stable light source for the ultra-fine straight pin lens 1, making the captured image clearer; the display screen is used for the camera system to control the host to display the image output, supports the HDIM2.0 interface, and supports up to 1080P images.

[0035] Reference Figure 5 The white light imaging image enhancement algorithm is a complete set of dedicated image adjustment and enhancement algorithms to achieve real-time video processing. The choledochoscope image may be interfered by various noises. Noise suppression processing can reduce the impact of noise on image quality and provide clearer images for subsequent image enhancement. During the examination, the choledochoscope may be blurred due to unstable hand-holding or changes in patient position. Motion blur removal can reduce this effect and improve image clarity.

[0036] In view of the imbalanced color proportion in choledochoscope images, color compensation is performed to balance the color distribution, especially to increase the values ​​of the green and blue channels of red-dominated pixels. In order to correct the color of the image, it is ensured that white objects appear as true white under different lighting conditions. White balance adaptation is achieved by adjusting the gain of the RGB sensor. Adaptive gamma correction is performed on the brightness component in the HSV color space to enhance the image brightness. This method changes the grayscale value of the image by adjusting the power exponential coefficient of the γ function so that the brightness and contrast of the image reach a suitable range. The brightness and contrast of the image are enhanced by combining the adaptive gamma correction brightness enhancement algorithm and the limited contrast adaptive histogram equalization algorithm CLAHE. This method first enhances the brightness of the input image, then improves the image contrast through the improved CLAHE algorithm, and finally combines the advantages of the two methods through a linear fusion strategy to obtain an enhanced image with rich details. The Retinex algorithm is optimized, and the R, G, B sub-channel differences of the image edge and adaptive histogram equalization are combined to correct the uneven illumination of the denoised video image, remove the highlights, and highlight the image details; by segmenting the image and calculating the dark channel image and mean channel image of each image block, the dark area is enhanced according to these parameters and the information of the surrounding image blocks, thereby improving the visual effect of the image and increasing the visibility of the details. A special spectral enhancement algorithm based on spectral transformation is adopted, combined with a high-pass filtering method based on increasing the spatial domain, the Sobel operator and the Laplacian operator are introduced, and the Gaussian smoothing filter and the Laplace sharpening filter are integrated to realize the blood vessel enhancement algorithm.
