A method for operating a sensor array of pixels which each generate a content corresponding to light incident thereon over an exposure period includes the following operations. The pixels are arranged into first and second regions and are reset such that the contents are cleared. The pixels are then exposed to receive light for a first exposure period. The exposure is then interrupted during which the content of each pixel in the first region is read. The pixels are then exposed to receive light for a second exposure period. The exposure is then interrupted during which the content of each pixel in the second region is read. The exposing and interrupting are performed without resetting the pixels such that the read content of each first region pixel depends on the first exposure period and the read content of each second region pixel depends on the first and second exposure periods.
