Imaging device and method having a control circuit to shift charges of the photodiode of each pixel simultaneously to a first storage node or a second storage node for capturing a moving object without distortion and achieving a wide dynamic range

摘要

An imaging device and a method of driving the imaging device including a plurality of pixels and a control circuit to apply a signal to the pixels, wherein the pixels include a photodiode, a floating diffusion node, a first storage node and a second storage node connected in parallel between the photodiode and the floating diffusion node, a first shift switching unit to selectively shift charges integrated in the photodiode to the first storage node, a second shift switching node to selectively shift the charges integrated in the photodiode to the second storage node, a first transfer switching unit to selectively transfer charges integrated in the first storage node to the floating diffusion node, a second transfer switching unit to selectively transfer charges integrated in the second storage node to the floating diffusion node, and a reset switching unit.

1. An imaging device, comprising:
a plurality of pixels; and a control circuit to apply a signal to the pixels, wherein the pixels comprise: a photodiode; a floating diffusion node; a first storage node and a second storage node to be connected in parallel to each other between the photodiode and the floating diffusion node; a first shift switching unit to selectively shift charges integrated in the photodiode to the first storage node; a second shift switching unit to selectively shift the charges integrated in the photodiode to the second storage node; a first transfer switching unit to selectively transfer charges integrated in the first storage node to the floating diffusion node; a second transfer switching unit to selectively transfer charges integrated in the second storage node to the floating diffusion node; and a reset switching unit to be disposed at one side of the floating diffusion node, wherein the control circuit applies the signal to shift charges of the photodiode of each of the plurality of pixels simultaneously to the first storage node or the second storage node from the photodiode.
