An imaging device causes a signal to be output from a first transfer line via a second transfer unit by a noise signal reading operation and a light-noise sum signal reading operation, the noise signal reading operation resetting a transfer capacitor when a signal of a charge converter is output to the first transfer line after a first transfer unit is turned into an OFF state and the charge converter is reset, and the light-noise sum signal reading operation outputting the signal of the charge converter to the first transfer line after the transfer capacitor resetting unit is turned into an OFF state, the first transfer unit is turned into an ON state, and a charge accumulated by a photoelectric conversion element is transferred.
