An imaging system in accordance with the present invention compensates for relative motion of the imaging system with respect to a scene to be captured. The imaging system includes an array, a light shield, a lens, a horizontal clocking system, and a vertical clocking system. The array includes at least two or more columns and rows of pixels, with each pixel exposed to the scene storing charge representative of the scene. The light shield is connected to the array and covers every other column of pixels. The lens is a focal length from the array and focuses the scene onto the array. The horizontal clocking system is coupled to each pixel in each row of the array and shifts charge from each pixel in each row exposed to the scene to each adjacent pixel in each row at a horizontal transfer frequency. The vertical clocking system is coupled to each pixel in each column covered by the light shield and shifts charge from each the pixel in each columns covered by the light shield to the next pixel in each column covered by the light shield at a vertical transfer frequency. The horizontal clocking system stops shifting charge between adjacent pixels in each row when an exposure time for capturing the scene expires. The imaging system may also include an imaging control system which determines a motion transfer rate which is the rate at which the scene moves down from one pixel in each column to the next pixel in each column. A method in accordance with the present invention includes the steps of exposing the columns and rows of pixels in the array to the scene, each pixel exposed to the scene storing charge representative of the scene, shifting charge from each pixel in each row exposed to the scene to each adjacent pixel in each of the rows at a horizontal transfer frequency, and shifting charge from each pixel in each of the columns covered by the light shield down to the next pixel in each column covered by said light shield at a vertical transfer frequency.
