Abstract
Suppressing a dead period at the time of mode switching. A solid-state imaging device includes: a plurality of pixels () that each outputs a luminance change of incident light; and a detection circuit () that outputs an event signal based on the luminance change output from each of the pixels, in which each of the pixels includes: a photoelectric conversion element () that generates a charge according to an incident light amount; a logarithmic conversion circuit () that is connected to the photoelectric conversion element and converts a photocurrent flowing out of the photoelectric conversion element into a voltage signal corresponding to a logarithmic value of the photocurrent; and a first transistor () having a drain connected to a sense node of the logarithmic conversion circuit.
