Abstract
In an integrated-circuit image sensor, binary sample values are read out from an array of pixels after successive sampling intervals that collectively span an image exposure interval and include at least two sampling intervals of unequal duration. Each pixel of the array is conditionally reset after each of the successive sampling intervals according to whether the pixel yields a binary sample in a first state or a second state.
