Camera module for vehicle
First Claim
1. A camera module for a vision system of a vehicle, said camera module comprising:
- a housing comprising a base portion and a lens portion, wherein said lens portion of said housing and said base portion of said housing comprise plastic material, and wherein said base portion is formed as a first injection molded part and said lens portion is formed as a second injection molded part separate from said base portion;
wherein said base portion of said housing comprises a first mating portion and wherein said lens portion of said housing comprises a second mating portion;
a circuit element including an imaging sensor and associated circuitry, wherein said imaging sensor comprises a CMOS imaging sensor having a dynamic range of greater than approximately 100 dB and less than approximately 120 dB, and wherein said dynamic range of said imaging sensor follows, at least in part, a non-linear response curve;
a lens;
wherein said first mating portion of said base portion and said second mating portion of said lens portion are welded together to substantially limit water intrusion into said camera module and wherein said camera module comprises shielding to limit or reduce electronic noise; and
wherein said camera module is configured for mounting at a rear portion of a vehicle equipped with said camera module, and wherein, when said camera module is mounted at the rear portion of the equipped vehicle, said imaging sensor has a rearward field of view, and wherein said camera module, when mounted at the rear portion of the equipped vehicle, is associated with a backup assist system of the equipped vehicle.

Abstract
A camera module for a vision system of a vehicle includes a housing, a circuit element and a lens. The housing has a base portion and a lens portion. The circuit element includes CMOS imaging sensor and associated circuitry. The CMOS imaging sensor has a dynamic range of greater than approximately 100 dB. The dynamic range of the imaging sensor may follow, at least in part, a non-linear response curve. The base portion and the lens portion are welded or sealed together to substantially limit water intrusion into the camera module and the camera module may include shielding to limit or reduce electronic noise. The camera module is configured for mounting at a rear portion of the vehicle so that the imaging sensor has a rearward field of view.
