A computer (1) displays, on a display portion (3), an image of an object which has been created by photographing by a photographing portion (18) in a setting mode. Further, height threshold-value data is received according to an input from outside through a key board (6A). Based on height information detected from the image created by photographing and based on the received threshold-value data, a partial image having height information specified by the threshold-value data is extracted from the image created by photographing and then is displayed on the display portion (3). In a driving mode, the computer (1) displays, on the display portion (3), an image acquired by photographing the object, and extracts a partial image having height information specified by the threshold-value data, based on the height information detected from the image created by photographing and the threshold-value data preliminarily-received in the setting mode. The image data extracted in the driving mode is utilized for inspections of defects in the object. |
