Abstract
In an integrated-circuit image sensor having a pixel array, a first subframe readout policy is selected from among a plurality of subframe readout policies, each of the subframe readout policies specifying a first number of subframes of image data to be readout from the pixel array for each output image frame and respective exposure durations for each of the first number of subframes of image data, wherein a shortest one of the exposure durations is uniform for each of the subframe readout policies. Each of the first number of subframes of image data is read out from the pixel array following the respective exposure durations thereof while applying a respective analog readout gain. The analog readout gain applied during readout of at least a first subframe of the first number of subframes is scaled according to a ratio of the shortest one of the exposure durations to the exposure duration of the first subframe.
