So as to improve the quality of the transmission of a signal, in particular an image or video signal, from an image sensor (3) to a camera controller (5) of an endoscopy arrangement (1) by a cable (4) while maintaining electrical safety standards, a first circuitry arrangement that is used to transmit the signal within the cable (4) is embodied with galvanic isolation from a second circuitry arrangement (19) that is used to further process the signal within the camera controller (5). The galvanic isolation (6) is formed to this end, preferably downstream of a proximal end (7) of the cable (4) in the signal direction, and the first circuitry arrangement has an impedance matching circuit (8), preferably with a passive embodiment, for example arranged at the proximal end (7) of the cable (4) or in the camera controller (5). 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 (3) to the camera controller (5), preferably in such a way that a frequency spectrum of the signal that is produced by the image sensor (3) can be reproduced.
