US Patent 11477401 Imaging device and imaging system

In an imaging device according to the present disclosure, during a period in which a signal from an amplifier transistor is output from a pixel via a select transistor, the gate voltage of the capacitance addition transistor changes frons the first voltage VH to the second voltage VL, and the amount of voltage change per time until the gate voltage changes from the first voltage VH to the second voltage VL is smaller than the amount of voltage change per unit time until the gate voltage changes from the second voltage VL to the first voltage VH.
