Abstract:
A solid-state imaging device includes: a first semiconductor substrate including a light receiver that receives incident light; and a second semiconductor substrate including an image processing circuit that processes a signal from the light receiver and generates an image signal. The second semiconductor substrate includes: a nonvolatile memory including a region in which use history data is stored; and a control circuit (use history securing circuit) that restricts output of the image signal when the use history data is stored in the nonvolatile memory.
