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 plurality of rows of image sensor elements spaced from each other, extending in a first direction, and being configured to sense a set of image elements of a target moving in the first direction, to integrate light from the rows of image sensor elements into corresponding pixel values, and to shift the pixel values along the rows of image sensor elements in the first direction according to a clock rate, the plurality of rows having the same number of image sensor elements, each row having image sensor elements that are different in length from the image sensor elements of the other rows; and a measurement module coupled with the plurality of rows of image sensor elements to measure the sharpness of detected image elements sensed by the image sensor elements in each row.
