Abstract
A plurality of pixels in a solid-state imaging device each include: a light receiving circuit that includes a light receiving element performing photoelectric conversion, sets, by an exposure signal, a photoelectric time for performing the photoelectric conversion, and outputs a light reception signal depending on whether or not incident light has reached the pixel within the photoelectric time; a counter circuit that counts, as a count value, the number of times the incident light has reached the pixel, based on the light reception signal; a comparison circuit that sets a value corresponding to the count value as a threshold, and sets a comparison signal to an on state in the case where the count value is greater than the threshold; and a storage circuit that stores, as a distance signal, a time signal when the comparison signal is in the on state.
