1. A camera module for a vehicle, said camera module comprising:

  • a housing that houses an imager assembly and a main circuit board;

    wherein the imager assembly comprises (i) an imager disposed on an imager circuit board and (ii) a lens assembly comprising a lens barrel accommodating at least one lens;

    wherein said housing comprises an upper cover and a lower cover, and wherein the upper cover and the lower cover are joined together;

    wherein the imager assembly is attached at an inner surface of the upper cover of said housing;

    a flexible ribbon cable extending from the imager circuit board, said flexible ribbon cable terminating at a terminator portion;

    wherein said terminator portion of said flexible ribbon cable comprises a first electrical connector;

    wherein said main circuit board comprises a printed circuit board (PCB) having a first planar side and an opposing second planar side separated from the first planar side by a thickness dimension of the PCB of said main circuit board;

    wherein first circuitry is disposed at the first planar side of the PCB of said main circuit board, and wherein second circuitry is disposed at the second planar side of the PCB of said main circuit board;

    wherein said second circuitry disposed at the second planar side of the PCB of said main circuit board comprises an image processor;

    wherein said image processor is operable for processing image data captured by the imager;

    wherein the PCB of said main circuit board at its second planar side comprises a second electrical connector, and wherein said second electrical connector at the second planar side of the PCB of said main circuit board is configured for connecting with said first electrical connector at the terminator portion of said flexible ribbon cable;

    wherein, with the imager assembly operated to capture image data and with said first electrical connector at the terminator portion of said flexible ribbon cable connected with said second electrical connector at the second planar side of the PCB of said main circuit board, image data captured by the imager of the imager assembly is provided via said flexible ribbon cable at least to said second circuitry disposed at the second planar side of the PCB of said main circuit board;

    wherein said housing, with said upper cover and said lower cover joined together, comprises a front portion and a rear portion;

    wherein said front portion is in front of said rear portion;

    wherein said main circuit board is accommodated within said front and rear portions;

    wherein the imager is accommodated within said rear portion and is not accommodated within said front portion of said housing;

    wherein said housing of said camera module has a breadth and a length, and wherein the PCB of said main circuit board extends across the breadth of said housing and along the length of said housing;

    wherein said rear portion of said housing has a height;

    wherein the maximum height dimension of said rear portion of said housing is greater than the maximum height dimension of said front portion of said housing;

    wherein said housing is adapted for detachable mounting at a mounting bracket attached at an in-cabin side of a windshield of a vehicle equipped with said camera module; and

    wherein the mounting bracket comprises mounting bracket structure that cooperates with corresponding housing structure of said housing to mount said camera module at the mounting bracket so that, with said camera module mounted at the mounting bracket attached at the windshield of the equipped vehicle, said camera module is mounted at the windshield with the imager viewing through a portion of the windshield in a forward direction of travel of the equipped vehicle.
