Low cost constructions of vehicular cameras employ various means for aligning and mounting the camera lens with respect to the imager. Such means include adhesive mounting using a UV curable adhesive, wherein the lens may be focused prior to cure of the adhesive. Other means include directly attaching the lens to the imager by adhesive; integrating the lens barrel and camera lens holder; dropping the lens barrel onto the surface of the imager; focusing the lens utilizing PCB mounting and focusing Screws; and focusing the lens by the relative positioning of camera front and back housings. Costs can also be contained by utilizing matching the resolution of the lens in conformance to human contrast sensitivity function, and by replacing optical chromatic aberration with digital chromatic aberration.
