Abstract:
A comparator in an AD conversion part performs, under the control of reading part, 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 PD 1  to an FD 1  in an integration period and a second comparison processing outputting a digitized second comparison result signal with respect to a voltage signal corresponding to a accumulated charge of the PD 1  transferred to the FD 1  in a transfer period after the integration period and, in the first comparison processing, starts an AD conversion processing comparing the voltage signal of the output buffer part and the reference voltage and outputting the digitized comparison result signal with a delay from the starting time of the first comparison processing. The comparator lowers a power consumption and suppresses an influence of a dark current of the FD and deterioration of an image.

Claim (Index 1):
A solid-state imaging device, comprising\n a pixel part in which pixels for performing photoelectric conversion are arranged and a reading part which reads out pixel signals f ran the pixels in the pixel part, wherein each pixel includes: a photoelectric conversion element which accumulates a charge generated by photoelectric conversion in an integration period, a transfer element capable of transferring the charge accumulated in the photoelectric conversion element in a transfer period after the integration period, an output node formed by a floating diffusion to which the charge accumulated in the photoelectric conversion element is transferred through the transfer element, an output buffer part which converts the charge at the output node to a voltage signal corresponding to a quantity of the charge and outputs the converted voltage signal, a comparator which performs comparison processing for comparing the voltage signal of the output buffer part and a reference voltage and outputting a digitized comparison result signal, and a memory part for storing data corresponding to the comparison result signal of the comparator, and the comparator, under the control of the reading part, performs a first comparison processing for outputting a digitized first comparison result signal with respect to the voltage signal corresponding to the overflow charge overflowing from the photoelectric conversion element to the output node in the integration period, and a second comparison processing outputting a digitized second comparison result signal with respect to the voltage signal corresponding to the accumulated charge of the photoelectric conversion element transferred to the output node in the transfer period after the integration period, and in the first comparison processing, starts an analog-to-digital (AD) conversion processing for comparing the voltage signal of the output buffer part and the reference voltage and outputting the digitized comparison result signal, with a delay from a starting time of the first comparison processing.
