ABSTRACT:
A solid state image pickup device110is provided with: a plurality of pixel units10that are arranged two-dimensionally and include a photoelectric conversion unit (photodiode PD) that converts light into a charge and an amplification unit (amplifier Q13) that converts the charge into a voltage and outputs it; a plurality of noise signal removal units (noise cancellation units40) that are provided one for each column and remove noises contained in the voltage outputted from the amplifier Q31of the pixel unit10belonging to the column; and a plurality of column amplification units (column amplifiers70) that amplify the voltage outputted from the amplifier Q13of the pixel unit10and output the amplified voltage to the noise cancellation unit40, and enables increase in sensitivity and reduction in noise with low power consumption.
