Abstract
Embodiments of the present invention are directed to an apparatus and a method for synchronizing the velocity of an image of a moving object or target and the clocking of image sensor elements used to track the moving target. In one embodiment, an imaging apparatus comprises a two-dimensional array of image sensor elements being configured to sense a first set of image elements of a target moving in a first direction with respect to the two-dimensional array of image sensor elements, to integrate light from the set of image elements into corresponding pixel values, and to shift the pixel values along the image sensor elements in the first direction according to a clock rate. A row of image sensor elements extends in the first direction to sense a second set of image elements of the target moving in the first direction. A synchronization module is coupled with the row of image sensor elements to measure the velocity of the target moving in the first direction based on a rate of movement of the second set of image elements of the target sensed by the row of image sensor elements, and to synchronize the clock rate of shifting the pixel values along the image sensor elements of the two-dimensional array with the velocity of the image elements of the target moving in the first direction.
