Abstract:
A solid-state imaging device which, in a voltage mode, simultaneously samples the pixel signal in all the pixels in a signal holding part serving as the pixel signal storage part, reads converted signals corresponding to readout signals held in a first signal holding capacitor and a second signal holding capacitor to a first signal line, reads converted signals corresponding to readout reset signals simultaneously in parallel to the second signal line, and supplies the same as a differential signal to a column readout circuit. Due to this, a sufficiently low parasitic light sensitivity corresponding to the application can be realized, settling error can be suppressed, and pixel fixed pattern noise can be reduced.

Claim (Index 13):
An electronic apparatus comprising\n a solid-state imaging device and an optical system forming a subject image in the solid-state imaging device, wherein the solid-state imaging device has a pixel portion in which are arranged pixels including photoelectric conversion reading parts and signal holding parts, a readout portion for reading pixel signals from the pixel portion, and a first signal line and a second signal line to which held signals of the signal holding part are output, wherein a pixel signal readout from a pixel is a pixel signal including at least a readout signal and a readout reset signal, and a photoelectric conversion reading part of the pixel includes at least an output node, a photoelectric conversion element which stores a charge generated by photoelectric conversion in a storage period, a transfer element capable of transferring the charge stored in the photoelectric conversion element in a transfer period, a floating diffusion to which a charge stored in the photoelectric conversion element is transferred through the transfer element, a first source-follower element which converts the charge of the floating diffusion to a voltage signal corresponding to the charge amount and outputs the converted signal to the output node, and a reset element which resets the floating diffusion to a predetermined potential in a reset period, and a signal holding part includes an input node, a first signal holding capacitor capable of holding a readout signal output from the output node of the photoelectric conversion reading part of the pixel and input to the input node, a second signal holding capacitor capable of holding a readout reset signal output from the output node of the photoelectric conversion reading part of the pixel and input to the input node, a first switch element which selectively connects the first signal holding capacitor with the output node of the photoelectric conversion reading part, a second switch element which selectively connects the second signal holding capacitor with the output node of the photoelectric conversion reading part, a first output part including a second source-follower element which outputs a signal held in the first signal holding capacitor in accordance with a held voltage and selectively outputting the converted signal to the first signal line, and a second output part including a third source-follower element which outputs a signal held in the second signal holding capacitor in accordance with a held voltage and selectively outputting the converted signal to the second signal line.
