Abstract
A pixel circuit () includes a photoelectric conversion circuit (), an integration capacitor (Cint) and a supplementary circuit (). The photoelectric conversion circuit () generates and outputs a photocurrent (Iphoto). The integration capacitor (Cint) includes a storage electrode (CintS) and a reference electrode (CintR), wherein the reference electrode (CintR) is connected to a first supply potential (VSUP), and wherein the integration capacitor (Cint) is configured to integrate the photocurrent on the storage electrode (CintS) in an integration period (Tint). The supplementary circuit () pre-charges a working node (WN) between the photoelectric conversion circuit () and the storage electrode (CintS) to a pre-charge potential (Vpre) that differs from the first supply potential (VSUP).
