Abstract: An extraction unit acquires a first difference between a non-defective product image, covering a non-defective product sample, and a reference model and a second difference between a defective product image, covering a defective product sample, and the reference model. A extraction unit extracts, as a potential defect, either the first difference or the second difference, whichever satisfies a particular condition. A calculation unit calculates at least one feature quantity with respect to the potential defect extracted by the extraction unit. When the defective product sample includes a plurality of defective product samples and respective feature quantities of the potential defects extracted from the defective product samples have multiple different values, the calculation unit specifies at least one of the feature quantities that has an Nth largest one of the multiple different values as an indicator. The presentation unit presents the indicator specified by the calculation unit.

Abstract: A camera device includes a camera unit, a movable unit, a fixed unit, a driving unit, a driving control unit, and a detection unit. The driving control unit controls the driving unit to drive the movable unit in rotation. The detection unit detects a predetermined type of operation performed by the user on at least one of the fixed unit or the movable unit. The driving control unit controls, when the detection unit detects the predetermined type of operation performed by the user, the driving unit such that the movable unit produces vibrations.
