Abstract:
1. An imaging device comprising: a pixel array section having an array of pixels each of which has a photoelectric converting device and outputs an electric signal according to an input photon, wherein the pixel array section including the pixels arranged in an array is formed on a first semiconductor substrate; a sense circuit section having a plurality of sense circuits each of which makes a binary decision on whether there is a photon input to a pixel in a predetermined period upon reception of the electric signal therefrom, wherein the sense circuit section including the plurality of sense circuits arranged in an array is formed on a second semiconductor substrate, and the first semiconductor substrate and the second semiconductor substrate are laminated one on the other; and a decision result IC section which integrates decision results from the sense circuits, pixel by pixel or for each group of pixels, multiple times to generate imaged data with a gradation, the decision result IC section including
