Abstract
Provided is an image sensor having a column ADC configuration including, for every pixel row, an analog digital converter (ADC) that converts a pixel signal including an analog signal generated by photoelectric conversion into an output signal including a digital signal. The image sensor includes a plurality of clamp operation units each configured to calculate a reference level based on each output signal of a plurality of ADC groups, and a reference voltage output unit configured to convert a digital signal of the reference level calculated by the clamp operation unit into a reference voltage including an analog signal, and supply the reference voltage to each the ADC that constitutes the ADC group.
