Patent abstract
A method and apparatus for achieving high-dynamic range operation with a set of spatially distributed pixel cells is provided. A pixel array with a row of pixels having apertures of varying sizes in a metal mask formed thereon controls the sensitivity of each pixel cell to light. A neutral density filter having varying light transparency values is also provided over the set of pixel cells to control the sensitivity of each pixel cell to light. The pixel cells voltage outputted is combined to obtain high-dynamic range operation.
