Abstract
To improve the quality of transmission of a signal from an image sensor to a camera controller of an endoscopy arrangement by a cable while maintaining electrical safety standards, a first circuitry arrangement used to transmit the signal within the cable includes galvanic isolation from a second circuitry arrangement used to further process the signal within the camera controller. The galvanic isolation is formed downstream of a proximal end of the cable in the signal direction, and the first circuitry arrangement has a, preferably passive, impedance matching circuit, for example arranged at the proximal end of the cable or in the camera controller. This impedance matching circuit is configured to compensate signal distortions, which arise during the transmission of the signal that is produced by the image sensor to the camera controller, preferably such that a frequency spectrum of the signal produced by the image sensor can be reproduced.
