Information processing device, determination area setting method, and determination area setting program

The present invention automatically sets an appropriate determination region in an image of an object to be inspected. An information processing device (1) is provided with: a detection unit (101) that detects, from an image (111) of an object to be inspected, a feature point whose positional relationship with a determination region to be an object to be inspected is known; and a setting unit (102) that sets the determination region on the basis of the feature point detected by the detection unit (101). 本发明自动地设定检查对象物的图像中的妥当的判定区域。信息处理装置(1)具备：检测部(101)，其从检查对象物的图像(111)中检测与应作为检查的对象的判定区域的位置关系为已知的特征点；以及设定部(102)，其以检测部(101)检测出的特征点为基准设定判定区域。
