1. An imaging system comprising:

  • an image sensor comprised of an array of pixel sensors defining a window, each pixel sensor in the array at a row address and a column address, the image sensor having a row input for selecting row address and a column input for selecting column address, the image sensor operative to generate a pixel output signal for the pixel sensor at the selected row address and the selected column address based on light incident upon the pixel sensor;

    an analog-to-digital converter in communication with the image sensor operative to digitize the output signal;

    a processor operative to generate instructions for the imaging system; and

    a control system in communication with the image sensor, the analog-to-digital converter, and the processor, the control system operative to(a) receive an instruction from the processor,(b) determine a first subwindow of the image sensor window based on the received instruction, and(c) determine the selected row address and the selected column address corresponding to each pixel in the subwindow.
