Abstract
An apparatus comprising an image sensor and a control logic circuit. The image sensor includes at least a first pixel array and a second pixel array, wherein at least some of the pixels of the first pixel array are interspersed over an image sensing area with pixels of the second pixel array. The control logic circuit is operable to control durations of exposure of the first pixel array and the second pixel array independently.
