1. A solid-state imaging device comprising:
a plurality of detection pixels that each output a luminance change of incident light;
a detection circuit that outputs an event signal based on the luminance change output from each of the detection pixels; and
a first common line connecting the plurality of detection pixels to each other,
wherein each of the detection pixels includes:
a photoelectric conversion element;
a logarithmic conversion circuit that converts a photocurrent flowing out of the photoelectric conversion element into a voltage signal corresponding to a logarithmic value of the photocurrent;
a first circuit that outputs a luminance change of incident light incident on the photoelectric conversion element based on the voltage signal output from the logarithmic conversion circuit;
a first transistor connected between the photoelectric conversion element and the logarithmic conversion circuit; and
a second transistor connected between the photoelectric conversion element and the first common line, wherein
the detection circuit includes a second circuit that outputs the event signal based on the luminance change output from each of the detection pixels.
