摘要： 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.

摘要： A method of manufacturing a vehicular camera, said method comprising providing a front camera housing having a cylindrical aperture having an aperture wall, providing a lens assembly comprising a lens barrel, the lens assembly including optical elements, inserting the lens barrel of the lens assembly at least partially into the cylindrical aperture of the front camera housing, securing the lens barrel of the lens assembly at the aperture wall of the cylindrical aperture of the front camera housing, providing a printed circuit board, wherein the printed circuit board comprises electronic circuity, and wherein the electronic circuitry of the printed circuit board comprises an imager, disposing an adhesive between the front camera housing and the printed circuit board, after disposing the adhesive between the front camera housing and the printed circuit board, adjusting the front camera housing and the printed circuit board relative to each other to achieve lens focus and optical axis alignment of the lens optics relative to the imager, wherein focusing and optical axis alignment of the lens optics relative to the imager is achieved via a multi-axis robot that is operable to adjust the lens optics relative to the imager, initially curing the adhesive via an initial curing process after the lens is brought into focus with the imager, wherein the initial curing process includes exposure to UV light for less than 7 seconds, wherein the adhesive, as cured to the initially-cured state via the initial radiation curing process, is sufficiently strong to (i) attach the printed circuit board relative to the front camera housing and (ii) hold the lens optics in focus and in optical axis alignment with the imager, after the initial curing process, moving the camera to the secondary curing process, further curing the initially-cured adhesive to a fully cured strength in a secondary curing process, and wherein, when further-cured via the secondary curing process, the further-cured adhesive is sufficiently strong to hold the lens assembly in position during use on a vehicle.
