Abstract
A pixel structure comprises an epitaxial layer () of a first conductivity type. A photo-sensitive element comprises a first region (4) of a second conductivity type and a second region (3) of the first conductivity type positioned between the epitaxial layer () and the first region (4). A charge storage node (ø2) is arranged to store charges acquired by the photo-sensitive element, or to form part of a charge storage element. A third region (2) of the second conductivity type is positioned between the charge storage node and the epitaxial layer. The pixel structure further comprises a charge-to-voltage conversion element () for converting charges from the charge storage node to a voltage signal and an output circuit () for selectively outputting the voltage signal from the pixel structure.
