Title: Solid-state image sensor and imaging system

Abstract: Each pixel includes a photo-electric converter, transfer switch, charge-voltage conversion node, amplifier, and control switch. A solid-state image sensor includes a voltage controller which controls the voltage of the charge-voltage conversion node of each pixel via the control switch of the pixel. A voltage set at the charge-voltage conversion node by the voltage controller via the control switch includes a first voltage (VD.sub.--1) for setting a pixel in a selected state, and a second voltage (VD.sub.--2) for setting the pixel in an unselected state. The voltage controller and the control switch of each pixel set the voltage of the charge-voltage conversion node of each pixel to the second voltage (VD.sub.--2) by using at least part of the horizontal scanning period.
