Abstract:
1. A solid-state image sensing device comprising: a unit pixel containing a photoelectric conversion element for detecting a light to generate photoelectrons and at least one electrode for forming an MOS diode structure; a first contact point connected to a first voltage supply for supplying a first voltage to the electrode; a second contact point connected to a second voltage supply for supplying a second voltage higher than the first voltage to the electrode; a first capacitor disposed between the first contact point and the second contact point; a change-over switch, which is connected to one of the first contact point and the second contact point to selectively switch a voltage applied to the electrode to the first voltage or the second voltage; pixel drive circuits for driving the change-over switch, thereby alternately applying the first voltage and the second voltage to the electrode to generate, hold, transfer, reset, or discharge the photoelectrons; a third contact point connected to a third voltage supply for supplying a third voltage higher than the first voltage and lower than the second voltage to the electrode; and a second capacitor disposed between the first contact point and the third contact point; wherein the pixel drive circuits control the change-over switch to apply the third voltage to the electrode in the processes of switching the voltage applied to the electrode from the first voltage to the second voltage and from the second voltage to the first voltage.
