Abstract:
[Problem] To provide a solid-state imaging device enabling summed-readout mode and cyclic-readout mode.
[Solution]
A device includes virtual-pixel units implemented by pixels of transfer-route controlling-scheme, the virtual-pixel units having a shape of polygon, the polygons are tessellated. The virtual-pixel unit encompasses a photoelectric-conversion region, charge detectors to which ordinal numbers are labeled, configured to accumulate signal charges transferred from the photoelectric-conversion region, and transfer-control elements configured to control movement of signal charges from the photoelectric-conversion region to one of the charge detectors. N pieces of charge detectors of the same ordinal number are arranged in boundary between the photodiodes and the intersection-shared sites. The intersection-shared site encompasses N pieces of switching elements having first main electrode connected to the charge detectors, and common signal-readout circuit having input terminals connected to second main electrode of each of the switching elements.
