System, apparatus and method for dark current correction

Abstract

Embodiments of the invention describe a system, apparatus and method for obtaining black reference pixels for dark current correction processing are described herein. Embodiments of the invention capture image signal data via a plurality of pixel cells of a pixel unit of an image device, wherein capturing image signal data involves establishing a first state of exposing incident light on each pixel of the pixel unit and a second state of shielding incident light from one or more pixels of the pixel unit via a shutter unit disposed over the pixel unit. Image signal data from each pixel of the pixel unit captured during the first state and the second state is read, and scene image data is created by combining a subset of image signal data captured during the first state with a dark current component including a subset of image signal data captured during the second state.
