The working principle and technology trend of Endoscope Camera

Endoscope Camera

The working principle of the endoscope camera

The endoscope camera is connected to the endoscope through an optical interface, and the optical signal collected by the endoscope is converted into a digital signal, which is input to the image processing host, and then processed by the image processing host and output to the display for display.

Imaging principle

The light emitted by the light source is transmitted to the human body through the main body of the endoscope through the transmission beam (optical fiber), and illuminates the part of the internal cavity tissue that needs to be inspected. The objective lens images the part to be inspected on the area array CCD, and the CCD is controlled by the CCD drive circuit. Capture images and output standard video signals. The adjustment mechanism is used to adjust the observation angle of the front end of the endoscope, which can be adjusted up and down, left and right, and rotated.

The key components of the endoscopic camera system are the image processing host and the endoscopic camera.

The image processing host is the control center of the entire camera system, used to process the surgical video and images captured from the camera. The front panel of the image processing host is mainly composed of a power button, a camera interface, a USB interface, and a white balance button. The rear panel is mainly a variety of video output interfaces and control interfaces, such as monitor, keyboard, mouse, etc.

The endoscope camera is mainly used for video and image collection. It converts the image signal collected by the endoscope into an electrical signal through a sensor, and then transmits it to the image processing host through a cable for processing.

Endoscope camera system has been widely used in various departments, clinically commonly used in otolaryngology, urology, gynecology, ophthalmology, orthopedics, neurosurgery, medical aesthetics and plastic surgery and other departments, suitable for otoscope, sinusoscope, nasopharyngoscope , Laparoscopy, Hysteroscopy, Arthroscopy, Intervertebral Foramoscope, Ureteroscopy, Fiberoptic Bronchoscopy and other fields of endoscopy.

Technology Trends of Endoscope Camera System

At present, the endoscope camera system is mainly developed in the direction of multi-function and high image quality. For example, noise reduction technology and edge enhancement technology are added in image processing technology; the image sensor is developed from CCD (charge coupled device) to CMOS (semiconductor device); at home and abroad; The mainstream endoscopic camera system is now 1080P (HD). With the maturity of imaging devices and display devices, the endoscopic camera system will develop from 2D and HD imaging to 3D imaging and 4K imaging. In the future, it will be 4K Ultra HD. The home field of the speculum camera system.
