1. A vision system for a vehicle, said vision system comprising:

  • a camera disposed at a vehicle and having a field of view exterior of the vehicle;

    a processor operable to process image data captured by said camera;

    a brightness control; and

    wherein said brightness control, responsive to image processing of a current frame of image data captured by said camera, interpolates towards an expected brightness for a next frame of captured image data by calculating a set of at least three brightness values using three different control coefficients derived from a previous frame of image data captured by said camera, and wherein said brightness control interpolates toward the expected brightness of the next frame of captured image data using the current expected brightness value and two of the three brightness values derived from the three control coefficients derived from the previous frame of captured image data.
