Imaging device, an endoscope system and method for removing noise

The imaging device includes a photoelectric conversion element, a first transfer portion, and a charge converting section, and the charge conversion unit reset unit, and a signal output unit, a first transfer line, the transfer capacity, a second transfer section , a transfer capacitor reset unit, and a second transfer line, and a driving portion, and the first transfer unit to the oFF state, after resetting the charge conversion unit, the signal of the charge conversion unit first when output to the first transfer line, and the noise signal read operation for resetting the transfer capacity, and the transfer capacitance reset unit to the oFF state, the first transfer unit is turned on and the photoelectric conversion element accumulated after transferring the charges, the optical noise sum signal read operation for outputting a signal of the charge conversion portion to the first transfer line, a signal through the second transfer portion from said first transfer line by to output.
