Abstract
PURPOSE:To decrease the influence by noise, and also to increase an output, by storing the charge of a vertical signal line in a capacitor through an MOSFET which is operated in a saturation mode, and reading it out. CONSTITUTION:A vertical switch 2 is selected at a horizontal flyback time by an output of a vertical scanning circuit 8, and charge of a photodiode 1 flows to a vertical signal line 3 through the MOSFET2. The charge of the vertical signal line 3 flows into the second electrode 13 of the first capacitor 14 through the first transmission gate 12 being an MOSFET, and charges the first capacitor 14. During the next horizontal scanning period, the first capacitor 14 stores charge of the photodiode 1. At the next horizontal flyback time, the second transmission gate 17 conducts, charge of a joint 13 is transferred to a joint 18, and the second capacitor is charged. Charge of a capacitor 19 is outputted to a horizontal signal line 5 through a horizontal switch 4.
