1. An apparatus, comprising: an image sensor partitioned into a plurality of image sensor regions, wherein a circuit board and the image sensor are un-integrated components such that the image sensor is attached to the circuit board; a lens array including a plurality of lenses disposed proximate to the image sensor, wherein each one of the plurality of lenses is arranged to focus a single image onto a respective one of the plurality of image sensor regions; and a spacer structure extending between the lens array and the circuit board to separate the lens array from the image sensor, wherein the spacer structure is bonded directly to the circuit board and surrounds a perimeter around all of the plurality of image sensor regions and the plurality of lenses such that none of the spacer structure is disposed between any of the plurality of lenses and the plurality of image sensor regions of the image sensor.
