Claim 7:
8. The method of claim 1, the step of determining the motion parameter comprising:
multiplying the pixel values of the short-exposure-time pixels, associated with the first color, with respective first fit weights according to a first model to determine a short-exposure-time first-color value for the image pixel;
multiplying the pixel values of unsaturated ones of the long-exposure-time pixels associated with the first color with respective second fit weights according to a second model to determine a long-exposure-time first-color value for the image pixel; and
calculating a disparity between the short-exposure-time first-color value and the long-exposure-time first-color value to determine the motion parameter;, wherein each of the first model and the second model is a two-dimensional polynomial function of sensor pixel location, and wherein output values of the two-dimensional polynomial function are the first fit weights or the second fit weights, respectively.
