Vehicular camera module with microlens array at imager

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;
• an outer lens at an opposite side of the microlens array from the imaging array sensor;
• wherein each individual microlens of the plurality of microlenses is associated with a respective sub-array of photosensors of 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 outer lens to be incident at the microlens array and 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 plurality of microlenses of the microlens array is incident at the respective sub-array of the photosensors of the imaging array sensor;
• wherein a focus length of at least one microlens of the plurality of microlenses is different from a focus length of at least one other microlens of the plurality of microlenses;
• wherein the focus length of each microlens of the plurality of microlenses is based on at least one selected from the group consisting of (i) an imaging plane of the imaging array sensor and (ii) a focus plane of the outer lens;
• wherein the vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system;
• and
• wherein, with the vehicular camera disposed at the vehicle, the vehicular camera has a field of view exterior the vehicle.
