Abstract:
1. A solid-state imaging device comprising: a sensor unit in which plural pixels are arranged; a vertical scanning unit and a horizontal scanning unit scanning pixels in the sensor unit; column amplifier units provided at respective vertical signal lines corresponding to columns in the sensor unit and amplifying signal charges read out to the vertical signal lines, the column amplifier units being capable of providing positive gains and negative gains for each of the columns; a bias current adjustment unit controlling current flowing in the vertical signal lines by changing bias current of the column amplifier units; a signal processing unit processing signal charges read out to the vertical signal lines and amplified by the column amplifier units into image signals to be output; an output unit to which signals output from the signal processing unit are supplied; a drive signal generation unit supplying drive signals to the vertical scanning unit, the horizontal scanning unit, the signal processing unit and the output unit; and an input unit supplying plural drive mode signals to the drive signal generation unit, and wherein,
