Patent JP-S6041376-A (JP)
Title: Solid-state image pickup device
Inventor: OZAKI TOSHIBUMI
IPC: H04N5/335
Filed: 1984-07-20
Abstract: PURPOSE:To reduce fixed pattern noise by providing the storing gate element of a bias electric charge on the way of a vertical signal line. CONSTITUTION:In a horizontal blanking period, an electric charge is flowed to a storage capacity from drain BLD of a blooming preventing MOSFET. When the drain BLD is set to a high level thereafter, a bias charge is left in the storage capacity. Next, the bias charge stored in the storage capacity is flowed to a vertical signal line 4. The bias charge is returned to the storage capacity, and an excess charge on the signal line 4 is flowed to the drain BLD. The bias charge stored in the storage capacity is flowed to the signal line 4 again. When a certain vertical gate line 90 obtains a high-level in this state, the signal charge of a photodiode 1 in a certain column is transferred to the signal line 4 and is mixed with the bias charge. Thereafter, the bias charge is left in the storage capacity, and only the signal charge is transferred to a CCD. These operations are performed in both of channels A and B. Thus, the quantity of bias charge which is inputted to the signal line 4 for the purpose of clearing the signal line 4 is made equal for each row.
