Claim 13:
14. The line-of-sight detection apparatus according to claim 7, wherein
the correction value determination unit determines the correction value such that, in a case where a plurality of feature positions of the detected subject are detected, the position of the line of sight corrected by the line-of-sight position correction unit matches any of the plurality of feature positions, and
the correction value determination unit determines the correction value such that, after a lapse of a predetermined time period, in a case where a degree of matching between the position of the line of sight corrected by the line-of-sight position correction unit and the any of the plurality of feature positions is less than a predetermined threshold value, the position of the line of sight corrected by the line-of-sight position correction unit matches a feature position which is different from the any of the plurality of feature positions, among the plurality of the feature positions.
