Abstract
An image sensor, system and method that alternates sub-sets of pixels with long exposure times and pixels with short exposure times on the same sensor to provide a sensor having improved Wide Dynamic Range (WDR). The sub-sets of pixels are reset at different time intervals after being read, which causes the respective integration times to vary. By combining information contained in the both the short and long integration pixels, the dynamic range of the sensor is improved.
