1. An information processing apparatus comprising: a face detecting unit that detects a face area included in image data; a face-component detecting unit that detects a face component from the face area detected by the face detecting unit; and a line-of-sight discriminating unit that executes line-of-sight discrimination processing for a face image from which the face component is detected by the face-component detecting unit, wherein the line-of-sight discriminating unit executes processing for discriminating whether a line of sight of the face image data from which the face component is detected is in a positive state in which a line of sight is directed in a camera direction or a negative state in which a line of sight is not directed in a camera direction according to collation processing for a line-of-sight discrimination dictionary in which learning data including classification data corresponding to the respective states are stored and input face image data.
