Abstract: A hardness tester includes an image acquirer acquiring an image of a surface of a sample captured by an image capturer, a test area definer defining a test area where the hardness test is performed with respect to the image of the surface of the sample displayed by a display which displays the acquired image of the surface, a test setting acquirer acquiring estimated hardness of the sample and test force when the hardness test is performed, an estimator estimating a size of the indentation to be formed on the surface of the sample based on the acquired test force and the estimated hardness, and a display controller displaying an image picture of the indentation to be formed, based on the estimated size of the indentation superimposed on the image of the surface of the sample displayed by the display.

Abstract: A hardness tester includes an image acquirer (controller) acquiring an image of a surface (surface image) of a sample captured by an image capturer, an identifier (controller) identifying, based on the surface image of the sample, a non-conformity region inside the image that is unsuitable for the hardness test using predetermined conditions, and a test position definer (controller) defining a test position in an area outside the non-conformity region identified by the identifier.
