Abstract
The solid-state imaging device includes: a first node for receiving a first signal from outside the solid-state imaging device; a second node for receiving a second signal from outside the solid-state imaging device; a test signal selection circuit for outputting the first signal received at the first node and the second signal received at the second node as a test signal by switching between the first and second signals at desired timing; and a test signal input circuit for supplying the test signal from the test signal selection circuit to an input of the A/D converter.
