1. A vehicular vision system suitable for use in a vehicle, said vehicular vision system comprising:

  • a camera module;

    said camera module comprising a camera;

    said camera comprising (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 camera, when mounted at a vehicle equipped with said vehicular vision system, is operable to capture image data representative of a scene exterior of the equipped vehicle;

    a flexible ribbon cable connecting to and extending from the imager circuit board;

    said flexible ribbon cable comprising electrical conductors that connect electrical circuitry of the imager circuit board to a terminator portion of said flexible ribbon cable, wherein said terminator portion comprises a first electrical connector;

    wherein the electrical circuitry of the imager circuit board comprises the imager;

    said camera module comprising a main circuit board, said main circuit board including a digital image processor for processing image data captured by the imager;

    wherein said main circuit board comprises a multilayered 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 multilayered PCB;

    wherein first circuitry is disposed at the first planar side of the multilayered PCB, and wherein second circuitry is disposed at the second planar side of the multilayered PCB;

    wherein said camera is disposed at the first planar side of the multilayered PCB;

    wherein said second circuitry disposed at the second planar side of the multilayered PCB comprises said digital image processor;

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

    wherein, with said camera module disposed at an equipped vehicle and with said camera operated to capture image data and with said first electrical connector at the terminator portion of said flexible ribbon cable mated with said second electrical connector at the second planar side of the multilayered PCB and with said flexible ribbon cable connecting to and extending from the imager circuit board, image data captured by the imager of said camera is provided via said flexible ribbon cable at least to said second circuitry disposed at the second planar side of the multilayered PCB;

    wherein image data provided via said flexible ribbon cable at least to said second circuitry disposed at the second planar side of the multilayered PCB is processed by said digital image processor for at least one driving assist system of the equipped vehicle;

    wherein said camera module comprises a housing;

    wherein said main circuit board is disposed within said housing;

    wherein said camera is at least partially disposed within said housing;

    wherein said housing encloses said main circuit board and the imager circuit board;

    wherein said housing comprises a front portion that is in front of a rear portion of said housing;

    wherein said main circuit board is enclosed within said front and rear portions of said housing;

    wherein said camera is at least partially housed within said rear portion of said housing;

    wherein said rear portion of said housing has an aperture;

    wherein at least a portion of said lens barrel of said camera extends through said aperture of said rear portion; and

    wherein said lens barrel of said camera protrudes outside said housing at an acute angle relative to said front portion of said housing.
