1. A sightline detecting method, comprising the steps of:
- detecting a facial image from within an entire image;
extracting a plurality of eye characteristic points from within eyes of the detected facial image;
extracting a plurality of facial characteristic points from facial parts that constitute a face within the facial image;
generating eye features that indicate the gazing direction of the eyes, employing the plurality of extracted eye characteristic points;
generating facial features that indicate the facing direction of the face, employing the plurality of extracted facial characteristic points; and
detecting a sightline, employing the generated eye features and the generated facial features.

Abstract
Detection of sightlines of faces within images is performed efficiently. A facial image is detected from within an entire image. A plurality of eye characteristic points and facial characteristic points are extracted from the detected facial image. Thereafter, eye features and facial features are generated, based on the extracted eye characteristic points and facial characteristic points. A characteristic vector that has the eye features and facial features as vector components is generated. A sightline is detected employing the generated characteristic vector.
