Abstract
A target setting apparatus sets a target correcting a sight line detection portion to detect a sight line of a subject person. A deviation between a position of the target and a position detected as a center of the sight line detected by the sight line detection portion when the subject person is estimated to be gazing at the target is regarded as a detection error and applied to a correction. The target setting apparatus includes: a sight line range estimation portion that estimates a sight line range; a candidate point extraction portion that extracts a candidate point for the target from the sight line range; a candidate point evaluation portion that evaluates appropriateness of the candidate point as the target by using a plurality of indices; and a target setting portion that determines whether or not to set the candidate point as the target.
