Abstract
An AD conversion part has a comparator for performing comparison processing comparing a voltage signal read out by a photoelectric converting and reading part and a reference voltage and outputting a digitalized comparison result signal, the comparator, under the control by a reading part, performs first comparison processing for outputting a digitalized first comparison result signal with respect to a voltage signal corresponding to an overflow charge overflowing from a photodiode PDto a floating diffusion FDin an integration period and second comparison processing for outputting a digitalized second comparison result signal with respect to a voltage signal corresponding to an accumulated charge of the photodiode PDtransferred to the floating diffusion FDin a transfer period after the integration period. Due to this, it becomes possible to substantially realize a broader dynamic range and higher frame rate.
