Summary:A seed value of a random number is generated in a more preferable manner by utilizing characteristics of a solid-state imaging device. A solid-state imaging device includes a pixel array unit in which a plurality of pixels is arrayed, and a processing unit that generates a seed value of a random number on the basis of each pixel value of predetermined one or more target pixels of the plurality of pixels, in which the pixel array unit is arranged on a first substrate, the processing unit is arranged on a second substrate, and a plurality of substrates including at least the first substrate and the second substrate is stacked so that the second substrate is located in a lower layer than the first substrate.
