Abstract
The present invention improves image quality while preventing a decrease in frame rate in a solid-state imaging element in which all pixels are exposed simultaneously. The solid-state imaging element includes a comparison unit, a pre-stage circuit, a capacitor unit, and a post-stage circuit. The comparison unit compares a signal level corresponding to an exposure amount with a predetermined threshold and outputs a comparison result. The pre-stage circuit converts charges into a voltage at a conversion efficiency selected from among a plurality of different conversion efficiencies on the basis of the comparison result and outputs the voltage. The capacitor unit holds the voltage. The post-stage circuit reads the voltage thus held and outputs the voltage to a vertical signal line.
