Abstract
The present disclosure relates to a solid-state imaging device, a driving method, and electronic equipment that permit imaging of a wide dynamic range image with higher quality. The solid-state imaging device includes a pixel region and a circuit region. A plurality of pixels that perform photoelectric conversion are arranged in the pixel region. At least a logarithmic conversion circuit is arranged in the circuit region. The logarithmic conversion circuit reads out a pixel signal from the pixel through a logarithmic readout scheme in which the pixel signal changes approximately logarithmically in proportion to the amount of light received by the pixel. Also, the logarithmic conversion circuit can switch between a logarithmic readout scheme and a linear readout scheme when the pixel signal is read out from the pixel. The present technology is applicable, for example, to a CMOS image sensor.
