ABSTRACT:
A solid-state imaging device of the present invention includes: a plurality of photoelectric conversion elements; a transfer section for transferring charges generated by the photoelectric conversion elements; a floating diode for converting the charges transferred by the transfer section to voltage signals; and an amplification section including a plurality of source follower circuits, each amplifying the voltage signals generated by the floating diode, wherein different power supply voltages are supplied to the respective source follower circuits, and the power supply voltages are reduced as the DC current flowing through each of the respective source follower circuits increases.
