Abstract
Detection cells configured to output signals for dark current error correction. Various embodiments of detection cells accumulate dark charge supplied by dark current sources, and output dark charge signals indicating the amount of accumulated dark charge. The dark charge signals may be used to approximate the amount of dark charge read out by pixel cells of an imaging array and/or to offset portions of pixel cell signals attributable to dark charge accumulation.
