SOLID-STATE IMAGE PICKUP APPARATUS, SIGNAL PROCESSING METHOD FOR A SOLID-STATE IMAGE PICKUP APPARATUS, AND ELECTRONIC APPARATUS

摘要

A solid-state imaging device includes a pixel array section that has at least one pixel with a photoelectric conversion unit and a charge detection unit. A driving section is configured to read out a signal of the pixel, a first portion of said signal being based on signal charge, a second portion of said signal being based on a reset potential. A signal processing section is configured to read out the first portion of the signal as a reference voltage, with the reference voltage being adjusted to cause the first and second portions of the signal to be within an input voltage range.
