1. A vehicular vision system, the vehicular vision system comprising:
a rear-viewing camera disposed at a vehicle equipped with the vehicular vision system, the rear-viewing camera viewing at least rearward of the equipped vehicle;
wherein the rear-viewing camera comprises a CMOS imaging array having at least one million photosensing elements arranged in rows and columns;
wherein the CMOS imaging array of the rear-viewing camera is operable to capture frames of image data;
wherein each frame of image data captured by the CMOS imaging array of the rear-viewing camera comprises a plurality of grids, with each grid of the plurality of grids comprising a respective set of photosensing elements associated with respective rows and columns of photosensing elements;
a processor operable to process frames of image data captured by the CMOS imaging array of the rear-viewing camera;
an electro-optic rearview mirror assembly, the electro-optic rearview mirror assembly comprising an electro-optic mirror reflective element that is controlled responsive to an ambient light condition at the equipped vehicle and a glare light condition rearward of the equipped vehicle;
wherein the ambient light condition is determined by processing at least one first grid of the plurality of grids of the frames of image data captured by the rear-viewing camera;
wherein the glare light condition is determined by processing at least one second grid of the plurality of grids of the frames of image data captured by the rear-viewing camera; and
wherein the at least one first grid of the plurality of grids of the frames of image data captured by the rear-viewing camera is different than the at least one second grid of the plurality of grids of the frames of image data captured by the rear-viewing camera.
