1. A vehicular vision system, said vehicular vision system comprising:

  • an image sensor disposed at a vehicle and having an exterior field of view, wherein said image sensor is operable to capture image data;

    an image processor operable to process captured image data;

    an electronic control unit (ECU);

    wherein said vision system is operable to automatically synchronize said image sensor to reference timing of said ECU;

    wherein said vision system regulates said image sensor between a fast mode and a slow mode, and wherein said vision system regulates said image sensor between said fast mode and said slow mode depending on whether a maximum buffer level achieved during processing of captured image data by said image processor exceeds a selected maximum buffer threshold; and

    wherein said vision system switches the timing of said image sensor to the slow mode when the maximum buffer level is greater than the selected maximum buffer threshold, and wherein said vision system switches the timing of said image sensor to the fast mode when the minimum buffer level is below the selected minimum buffer threshold.
