Abstract
An imaging system and method for producing a digital image from pixel signals captured by a pixel array is disclosed. First pixel signals, generated during a first exposure period, are read out from a first group of pixels of the pixel array. The first group of pixels is reset after reading out the first pixel signals. Second pixel signals from the first group of pixel are read out after resetting the first group of pixels. The second pixel signals are generated during a second exposure period. Third pixel signals from a second group of pixels of the pixel array are read out. The third pixel signals are generated during a third exposure period that overlaps at least a portion of the first and second exposure periods. The first, second, and third pixel signals are used to produce the digital image.
