Abstract
A solid state image pickup deviceis provided with: a plurality of pixel unitsthat are arranged two-dimensionally and include a photoelectric conversion unit (photodiode PD) that converts light into a charge and an amplification unit (amplifier Q) that converts the charge into a voltage and outputs it; a plurality of noise signal removal units (noise cancellation units) that are provided one for each column and remove noises contained in the voltage outputted from the amplifier Qof the pixel unitbelonging to the column; and a plurality of column amplification units (column amplifiers) that amplify the voltage outputted from the amplifier Qof the pixel unitand output the amplified voltage to the noise cancellation unit, and enables increase in sensitivity and reduction in noise with low power consumption.
