1. A camera module for a vehicular vision system, the camera module comprising:

  • a camera housing comprising an upper housing portion and a lower housing portion;

    wherein said camera housing, with said upper housing portion connected to said lower housing portion, houses at least (i) electronic circuitry disposed at a main printed circuit board (PCB) and (ii) an imager assembly;

    wherein said imager assembly comprises an imager;

    wherein said imager comprises a two dimensional array of rows and columns of photosensing elements;

    wherein said imager comprises at least one million photosensing elements;

    wherein said imager assembly comprises a lens barrel that houses at least one lens;

    wherein said imager assembly comprises an imager PCB;

    wherein electronic circuitry disposed at said imager PCB of said imager assembly comprises said imager;

    wherein said main PCB has an upper side and a lower side;

    wherein electronic circuitry of said main PCB is disposed at said upper side of said main PCB and at said lower side of said main PCB;

    wherein said lower side of said main PCB faces said lower housing portion and said upper side of said main PCB faces said upper housing portion;

    wherein said imager assembly comprises a flexible cable that, when connected to a connector at said main PCB, connects electronic circuitry disposed at said imager PCB with electronic circuitry disposed at said main PCB;

    wherein an electronic component of electronic circuitry disposed at said main PCB is in thermal conductivity with a thermal element;

    wherein said thermal element is in thermal conductivity with said lower housing portion of said camera housing;

    wherein said thermal element comprises a thermally conductive resilient material that enhances heat transfer from the electronic component of electronic circuitry disposed at said main PCB to said lower housing portion of said camera housing;

    wherein said thermally conductive resilient material of said thermal element is compressed when in thermal conductivity with said lower housing portion of said camera housing;

    wherein the camera module is configured to attach at an in-cabin side of a windshield of a vehicle equipped with the vehicular vision system; and

    wherein, with the camera module attached at the in-cabin side of the windshield, said imager views through the windshield forward of the equipped vehicle.
