Abstract
A pixel array includes a plurality of pixel structures, with each pixel structure having a photo-sensitive element for generating charge in response to incident light; a charge conversion element; a first transfer gate and a second transfer gate connected in series between the photosensitive element and the charge conversion element or between the photosensitive element and a supply line; and an output stage. A first transfer gate control line is connected to the first transfer gates of a first sub-set of the pixel structures in the array; and a second transfer gate control line connected to the second transfer gates of a second sub-set of the pixel structures in the array. The first sub-set of pixel structures and second sub-set of pixel structures partially overlap, having at least one pixel structure in common between them.
