1. A vehicular camera, the vehicular camera comprising:
an imaging array sensor, and wherein the imaging array sensor comprises at least one million photosensors arranged in rows and columns;
a microlens array;
wherein the microlens array comprises a plurality of microlenses disposed at the imaging array sensor;
wherein each individual microlens of the plurality of microlenses comprises a respective plurality of refractive indices;
wherein the microlens array is disposed at the imaging array sensor so that light incident at the vehicular camera passes through the microlens array to be incident at the imaging array sensor;
wherein light incident at and passing through each individual microlens of the microlens array is incident at a respective sub-array of the photosensors of the imaging array sensor;
wherein each individual microlens of the plurality of microlenses of the microlens array comprises a first planar surface and an opposing second planar surface separated from the first planar surface by a plate thickness dimension of the individual microlens, and wherein light incident at the vehicular camera passes through the first planar surface and through the plate thickness dimension of the respective individual microlens to exit the second planar surface of the respective individual microlens to be incident at the respective sub-array of the photosensors of the imaging array sensor associated with that respective individual microlens; and
wherein the vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system.
