Abstract

See full text

Provided is a solid-state imaging device that includes a high sensitivity floating diffusion (FD) and a low sensitivity FD that hold a charge generated in a photodiode PD of a pixel, an FD coupling transistor that turns on and off coupling of the high sensitivity FD and the low sensitivity FD, and a saturation sensing circuit that performs a control that couples the high sensitivity FD and the low sensitivity FD, when a voltage of a pixel signal outputted from the pixel matches a voltage of a ramp signal. A level of the ramp signal varies in accordance with elapsed time.
