Abstract
A comparator in an AD conversion part, under the control of a reading part, performs a first comparison processing outputting a digitized first comparison result signal with respect to a voltage signal corresponding to an overflow charge overflowing from a photodiode PDto FDin an integration period and performs a second comparison processing outputting a digitized second comparison result signal with respect to a voltage signal corresponding to an accumulated charge of the photodiode PDtransferred to the FDafter a transfer period after the integration period, and a signal processing part performs combinational processing applying FWC information and joining a first AD conversion transfer curve TCcorresponding to the first comparison processing and a second AD conversion transfer curve TCcorresponding to the second comparison processing. Thus, it is possible to smoothly switch (connect) a plurality of signals to be combined and to suppress deterioration of an image.
