1. A method, comprising:
setting an integration time for a readout circuit of a plurality of readout circuits based on a speed of a target desired to be captured in a fast frame image, the plurality of readout circuits configured to read a plurality of pixels in an image detector, the plurality of pixels having a pitch of less than ten micrometers, the integration time being not more than five hundred microseconds, the integration time corresponding to a subframe of the fast frame image, wherein the integration time is based on a dwell time of the target in a pixel of the plurality of pixels, and wherein the setting the integration time further includes:
setting the integration time to be not more than twenty multiplied by the dwell time;
performing a plurality of integrations of each readout circuit based on the integration time to provide a plurality of subframes; and
averaging a number of the plurality of the subframes to provide the fast frame image.
