    generate face data and detection object data from the second image data, the face data representing a face of the operator and articles worn by the operator, and the detection object data being obtained by excluding the face data from the second image data and representing a remaining portion of the second image data other than the face data;

    detect a motion of an object in the second image data based on the detection object data by comparing the detection object data with a former detection object data, the object being included in the detection object data, the motion of the object indicating a positional change of pixels representing the object in the detection object data, and the former detection object data being generated from the first image data acquired at the first capturing period; and

    determine a condition of the operator in accordance with the motion of the object.
