An apparatus and a method for synchronizing the velocity of an image of a moving object and the clocking of image sensor elements used to track the moving target. The imaging apparatus includes a two-dimensional array of image sensor elements being configured to sense a first set of image elements in a first direction according to a clock rate. A plurality of rows of image sensor elements are spaced from each other. The rows of image sensor elements are configured to sense a second set of image elements of the target moving in the first direction according to the clock rate. Each row has image sensor elements that are different in length from the image sensor elements of the other rows. A measurement module is coupled with the plurality of rows of image sensor elements to measure the sharpness of detected image elements and to identify the row of image sensor elements having the sharpest detected image elements.
