Abstract

A hardness tester includes a CCD camera, a monitor, a clipper (a CPU and a clipping program), and a display controller (the CPU and a display control program). The CCD camera captures an image of an indentation formed on a surface of a specimen via field lenses. The monitor displays the image of the indentation captured by the CCD camera. The clipper clips a plurality of regions from the image of the indentation captured by the CCD camera, the plurality of regions each containing a respective vertex. The display controller simultaneously displays on the monitor images of the plurality of regions clipped by the clipper.
