• wherein the ECU is disposed within the vehicle remote from the vehicular interior rearview mirror assembly;
• wherein, with the vehicular interior rearview mirror assembly mounted at the interior portion of the vehicle, image data captured by the driver monitoring camera is provided to the ECU via a coaxial cable and is processed at the ECU;
• and
• wherein, with the vehicular interior rearview mirror assembly mounted at the interior portion of the vehicle, and based at least in part on processing at the ECU of image data captured by the driver monitoring camera, the vehicular vision system adjusts processing of image data captured by the driver monitoring camera to accommodate adjustment of the mirror head when the driver adjusts the mirror head to adjust his or her rearward view.
