Abstract: A solid-state image-sensing device includes a pixel array and an averaging unit. The pixel array includes a matrix of pixels and includes a respective output line for each of a plurality of pixel groupings such as for each column of pixels. The averaging unit receives respective signals from first and second output lines of the pixel array to generate a pulse width signal that indicates an average of such respective signals. A respective signal of the first output line is generated from combining photocurrents from a first set of at least two pixels sensing a same first color in the pixel array.
