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
Abstract:
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.
