Abstract:
1. An imaging device having an integrated array of a plurality of pixels, each pixel comprising: a photodiode that receives light and that generates photoelectric charges; a transfer transistor connected to the photodiode the transfer transistor transferring the photoelectric charges received from the photodiode; a floating region coupled to the transfer transistor, to which the photoelectric charges are transferred via the transfer transistor; a storage capacitor element; a storage transistor connected between the floating region and the storage capacitor element; and a reset transistor directly connected to the connecting point of the storage transistor and the storage capacitor element, the reset transistor discharging the photoelectric charges of the storage capacitor element; wherein said transfer transistor and said storage transistor are directly connected to said floating region and said reset transistor is not directly connected to said floating region, wherein the photoelectric charges overflowing from the photodiode are accumulated in the storage capacity element in an accumulation interval.
