演算手段とを備えてなる変位計。 It is a displacement meter that uses an image sensor to read the gauge marks displayed on the test piece with contrast between light and dark, and detects the displacement between the gauge marks. A comparator that binarizes into bright and dark by comparing with the slice signal, and a change point from bright to dark or from dark to bright in the bright/dark identification signal output from the comparator are taken up, and the first change point and the second change point are A displacement meter comprising calculation means for calculating and detecting a midpoint position of a change point as a gauge position.
