• a front camera disposed at an exterior portion of the equipped vehicle;
• wherein, with the front camera disposed at the exterior portion of the equipped vehicle, the front camera at least views forward of the equipped vehicle;
• wherein the front camera comprises an imaging sensor comprising an array of at least one million photosensor elements arranged in multiple columns and multiple rows, and wherein the front camera is operable to capture image data;
• wherein the front camera comprises a second serializer operable to serialize image data captured by the front camera;
• wherein the ECU comprises a second de-serializer, and wherein the front camera connects with the ECU via a second cable, and wherein image data captured by the imaging sensor of the front camera is converted at the second serializer to second serialized image data that is carried to the ECU via the second cable;
• wherein second serialized image data carried to the ECU via the second cable is de-serialized at the second de-serializer of the ECU to form second de-serialized image data;
• wherein the front camera and the rear backup camera are part of a multi-camera surround view system of the equipped vehicle, and wherein the multi-camera surround view system of the equipped vehicle includes four cameras comprising (i) the front camera, (ii) the rear backup camera, (iii) a driver-side sideview camera and (iv) a passenger-side sideview camera;
• wherein image data captured by the four cameras of the multi-camera surround view system of the equipped vehicle is provided to, and is processed at, the ECU;
• and
• wherein, responsive to processing at the ECU of image data captured by the four cameras and provided to the ECU, surround view video images of an environment at least partially surrounding the equipped vehicle are displayed at the video display device.
