1. A method of estimating motion of a moving object, said method comprising the steps of:

  • capturing at least first and second blurred images of the moving object, the blur in the first and second blurred images arising from at least motion blur of the object, wherein exposure durations of the first and second blurred images overlap at least partially;

    generating an error function, the error function being a function of the first blurred image and the second blurred image;

    minimising the error function; and

    estimating the motion of the object from the minimised error function.
