Abstract
An image pickup device for dimensional measurement comprises a first pixel train serving as a main scale, comprised of pixels arranged at a first pitch (Pm); and a second pixel train serving as a vernier, comprised of pixels arranged at a second pitch (Ps) set to a length different from the first pitch (Pm), and disposed in parallel to the first pixel train. The second pixel train may employ an arrangement comprising N pixel trains, in which adjacent pixel trains are positionally shifted in succession by the second pitch (Ps). In this case, the second pitch (Ps) has the relationship of Pm/N (N is an integer equal to 3 or more) with respect to the first pitch (Pm).
