Abstract: A vehicular camera includes an imaging array sensor that includes one million photosensors arranged in rows and columns and a microlens array. The microlens array includes a plurality of microlenses disposed at the imaging array sensor. Each individual microlens of the plurality of microlenses includes a respective plurality of refractive indices. 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. 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. The vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system.

Abstract: A vehicular camera includes an imaging array sensor and a microlens array that includes a plurality of microlenses disposed at the imaging array sensor. Each individual microlens is associated with a respective sub-array of photosensors of the imaging array sensor and has a respective plurality of refractive indices. 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. Light incident at and passing through each individual microlens is incident at the respective sub-array of the photosensors. 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. The vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system.

Abstract: A vehicular occupant monitoring system includes a camera disposed at an interior rearview mirror of a vehicle. A polarization filter is disposed between an imaging array sensor of the camera and occupants of the vehicle such that light reflected off of the occupants of the vehicle passes through the polarization filter prior to reaching the imaging array sensor. The vehicular occupant monitoring system, responsive to processing by the image processor of image data captured by the camera, determines presence of an occupant of the vehicle.
