1. An information processing apparatus, comprising: a first imaging section configured to image a holding platform which is made from a light-transmitting material from different directions; a second imaging section configured to image the holding platform from below the holding platform; a recognition section configured to, read out the characteristics of an object image of an object which is held on the holding platform based on each of the first images that are respectively imaged by the first imaging section from different directions and compare the read characteristics with pre-stored characteristics of each object, thereby recognizing the object corresponding to the object image every first image; a determination section configured to determine a recognition result of the object held on the holding platform based on a recognition result of the object image every first image; a comparison section configured to compare the number of the object images contained in a second image that is imaged by the second imaging section with the number of the objects that are determined by the recognition result; and a report section configured to report according to a comparison result of the comparison section.
