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, (ii) a lens barrel accommodating at least one lens, (iii) a lens holder, and (iv) a flexible ribbon cable extending from the imager circuit board, said flexible ribbon cable terminating at a terminator portion;

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

    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 circuitry disposed at the PCB of said main circuit board comprises (i) first circuitry disposed at the first planar side of the PCB of said main circuit board and (ii) second circuitry disposed at the second planar side of the PCB of said main circuit board;

    wherein circuitry disposed at 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 comprises a second electrical connector, and wherein said second electrical connector 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 said first electrical connector at the terminator portion of said flexible ribbon cable electrically connects with said second electrical connector of the PCB of said main circuit board;

    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 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 to circuitry disposed at 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 breadth and 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 height;

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

    wherein the upper cover at said rear portion of said housing comprises an opening, and wherein the imager views to exterior of said housing via said opening;

    wherein the lens barrel extends through said opening to protrude outside said housing;

    wherein the lens barrel of the imager assembly is tilted at an acute angle upward relative to the plane of the PCB of said main circuit board; and

    wherein the first circuitry disposed at the first planar side of the PCB of said main circuit board comprises an electrical socket connector configured for electrical connection to a plug connector of a vehicular wire harness.
