Abstract
This disclosure concerns a solid-state imaging device including a pixel thermally separated from a substrate; a heat conduction switch having one end connected to the substrate and other end capable of contacting to the substrate or the pixel, the heat conduction switch changing over a state of the pixel to one of a first state and a second state, the first state being a state in which the pixel is thermally isolated from the substrate by causing the other end of the heat conduction switch to contact with the substrate, the second state being a state in which the pixel is thermally shorted to the substrate by causing the other end of the heat conduction switch to contact with the pixel; and a signal detector detecting a difference between the signal voltage of the pixel in the first state and the signal voltage of the pixel in the second state.
