Abstract
Embodiments provide a method and apparatus that achieve wide dynamic range operation of an image sensor. In an array of pixel cells, first charge is accumulated in a first subset of pixel cells during a first integration period and second charge is accumulated in a second subset of pixel cells during a second integration period. A length of the first integration period is different than a length of the second integration period, and the first and second charge are accumulated during a same frame and are read out.
