ABSTRACT:
An image sensor comprises a pixel array, and a control unit which performs, in a first period, a control operation of an electric potential of a signal line to turn off a MOS transistor while the electric potential of a charge-voltage converter in a selected pixel is maintained at an electric potential of a selected state, and, in a second period subsequent to the first period, performs a control operation of the electric potential of the signal line to turn on the MOS transistor while the electric potential of the charge-voltage converter in the selected pixel is maintained at an electric potential of the selected state.
