1. A vehicular vision system, the vehicular vision system comprising:
a rearward-viewing camera disposed at a vehicle equipped with the vehicular vision system, wherein the rearward-viewing camera views at least rearward of the equipped vehicle;
wherein the rearward-viewing camera comprises an image sensor having at least one million photosensing elements arranged in rows and columns;
wherein image data captured by the rearward-viewing camera is provided to an electronic control unit;
a forward-viewing camera disposed at the equipped vehicle, wherein the forward-viewing camera views at least forward of the equipped vehicle;
wherein the forward-viewing camera comprises an image sensor having at least one million photosensing elements arranged in rows and columns;
wherein image data captured by the forward-viewing camera is provided to the electronic control unit;
wherein the electronic control unit sends respective control data to the rearward-viewing camera and to the forward-viewing camera, and wherein the respective sent control data is stored in respective memory of the rearward-viewing camera and the forward-viewing camera;
wherein, with the respective sent control data stored in the respective memory of the rearward-viewing camera and the forward-viewing camera, the electronic control unit sends a trigger signal to the rearward-viewing camera and to the forward-viewing camera;
wherein, responsive to the sent trigger signal, the rearward-viewing camera and the forward-viewing camera load operational parameters of the respective control data stored in the respective memory of the rearward-viewing camera and the forward-viewing camera into respective image sensors of the rearward-viewing camera and the forward-viewing camera so that the operational parameters of the respective image sensors of the rearward-viewing camera and the forward-viewing camera are synchronized; and
wherein, with the operational parameters of the respective image sensors of the rearward-viewing camera and the forward-viewing camera synchronized, image data is captured by the respective image sensors of the rearward-viewing camera and the forward-viewing camera and is sent to the electronic control unit.
