In some examples, the power signal is transmitted by the second connection interface to the camera unit through a single core transmission line to provide power to the camera unit. For example, the power signal output by the host terminal 244 of the camera host 240 may be coupled to a single-core transmission line via a cable plug-in terminal, and then be decoupled after being transmitted to the camera unit by the single-core transmission line, thereby powering the camera unit.

The third isolation unit 3442 is used for isolating a power signal between the image capturing unit and the image capturing host, and the second isolation unit 3424 is used for isolating an image signal and/or a control signal between the image capturing unit and the image capturing host.

The data receiving unit 4422 and the data transmitting unit 424 realize signal transmission between the image capturing unit and the image capturing host. In this example, the isolation unit is disposed at the cable mating end, so that the host end can directly use the camera unit of the cable even without isolation, and can be connected to different host ends (the host end including the isolation unit or the host end not including the isolation unit), so that the product applicability is wider.

Referring to fig. 5, a schematic diagram of an overall circuit architecture of a medical endoscopic imaging system 500 is provided.
