Principle of three-chip endoscope camera system
The light emitted by the light source is transmitted to the human body through the beam transmission (fiber), through the main body of the endoscope, and illuminates the part of the cavity tissue in the human body that needs to be examined. The objective lens imaginates the part to be examined on the area array CCD, and the CCD driver circuit controls the CCD to collect images and output standard video signals. The adjusting mechanism is used to adjust the viewing Angle of the front end of the endoscope, which can be adjusted up and down, left and right adjustment and rotation adjustment.
The key components of endoscope camera system are image processing host and endoscope camera.
The image processing host is the control center of the entire camera system, which is used to process the surgical videos and images captured from the camera. The front panel of the image processing host is mainly composed of power button, camera interface, USB interface, white balance button and so on. The rear board is mainly a variety of video output interface and control interface, such as display, keyboard, mouse and so on.
The endoscope camera is mainly used for video and image acquisition, which converts the image signal collected by the endoscope into an electrical signal through the sensor, and then transmits it to the image processing host through the cable for processing.
