PURPOSE:To attain the storage for a very short time, by performing a clear scanning and readout scanning with shifted phase for a prescribed difference. CONSTITUTION:A horizontal MOSFET switch 113 has a gate electrode 125 to which a clear pulse is impressed from a clear register 111 at an X position. A source 26 of an MOSFET13 is common to the source of the MOSFET 113. The drain 127 of the MOSFET 113 flows a charge to a horizontal clear line 122 via an electrode 128. One end of the clear line 122 is connected to an MOSFET switch 116, which is switched with a clear pulse from a Y position clearing register 112. After the charge stored in a photo diode section 14 is cleared via the clear line 122, the photo diode charged up to a target voltage is discharged in response to the amount of light incident at the period until the charge is outputted with the readout scanning. |
