Abstract: The present invention realizes an information processing device capable of accurately differentiating an object from within an imaged image regardless of imaging conditions. The present invention also realizes an information processing method and a control program. A first circumscribed polygon region calculation unit (32) calculates a first circumscribed polygon region as a convex hull circumscribed region that contains a feature region. A principal axis of inertia calculation unit (33) calculates a principal axis of inertia for the feature region. A region division unit (34) uses the principal axis of inertia to divide the feature region. On the basis of the area ratio of the two second circumscribed polygon regions and the first circumscribed polygon region as convex hull circumscribed regions that respectively contain the divided feature regions, a region selection unit (36) selects either the first circumscribed polygon region or the two second circumscribed polygon regions.
