Abstract
Photocharge is integrated within a first plurality of pixels of an integrated-circuit image sensor during a first exposure interval. A read-out signal is output from each pixel of the first plurality of pixels upon conclusion of the first exposure interval, each read-out signal indicating a respective level of photocharge integrated within the corresponding pixel during the first exposure interval. Photocharge is also integrated within a second plurality of pixels during a second exposure interval that transpires concurrently with the first exposure interval and has a duration not more than half the duration of the first exposure interval. A read-out signal is output from each pixel of the second plurality of pixels at least twice with respect to the second exposure interval, with each such read-out signal indicating a respective level of photocharge integrated within the corresponding pixel during at least a portion of the second exposure interval.
