A solid-state imaging device according to an embodiment includes a plurality of pixels (20a) arrayed in a two-dimensional lattice, and a control unit (115). The pixel includes a first light receiving element (401a) that outputs a first photocurrent corresponding to received light, a second light receiving element (401b) that outputs a second photocurrent corresponding to received light, a conversion unit (300) that converts a current into a voltage, an output unit (320 or 330) that detects an event based on a change in the voltage converted by the conversion unit, and outputs a detection signal indicating a detection result of the detection, and a switch unit (113a) that performs switching of switching the current to be converted into the voltage by the conversion unit between the first photocurrent and the second photocurrent. The control unit controls the switching performed by the switch unit.
