More Information
Summary:A solid-state imaging device includes: a pixel including a photoelectric converter that generates a charge and a charge accumulator that converts the charge into a voltage; a controller that causes the pixel to perform exposure in a first exposure mode and convert the charge into the voltage with a first gain to output a first pixel signal, and causes the pixel to perform exposure in a second exposure mode and convert the charge into the voltage with a second gain to output a second pixel signal, the second exposure mode being shorter in exposure time than the first exposure mode, and the second gain being lower than the first gain; and a signal processor that synthesizes the second pixel signal after amplification and the first pixel signal.
