Abstract
Disclosed herein is a solid-state image pickup apparatus, including a pixel array section in which a unit pixel including a photoelectric conversion section and a charge detection section for detecting charge generated by photoelectric conversion by the photoelectric conversion section is disposed; a driving section adapted to carry out driving of reading out a signal of the unit pixel divisionally by twice as a first signal and a second signal; and a signal processing section adapted to set the first signal read out first from the unit pixel as a reference voltage for a processable input voltage range of the signal processing section, adjust the reference voltage so that the first and second signals may be included in the input voltage range and carry out signal processing for the first and second signals using the adjusted reference voltage.
