PROBLEM TO BE SOLVED: To provide an eyelid opening/closing detector capable of accurately determining opening/closing of eyelids of a subject without using sequential images in time series and an eyelid opening/closing detection method.SOLUTION: The eyelid opening/closing detector includes: an initial detection part for detecting an area of eyes from a face image of a subject generated on the basis of an output of an imaging device which has picked up the face of the subject; an edge intensity image generation part for generating an edge intensity image from the area of the eyes; a pair extraction part for extracting a plurality of pairs of an upper eyelid candidate point and a lower eyelid candidate point on the basis of the edge intensity image; a grouping part for grouping each of the plurality of pairs in such a manner that a pair adjacent to each other on right and left sides having a closer distance between each other belong to the same group; and an opening/closing determination part for determining opening/closing of the eyelids of the subject on the basis of a feature amount of the group.SELECTED DRAWING: Figure 3

    【課題】時系列的に連続した画像を用いずとも高精度に被写体の瞼の開閉判定を行なうことができる瞼開閉検出装置および瞼開閉検出方法を提供する。【解決手段】本発明の一実施形態に係る瞼開閉検出装置は、被写体の顔を撮像した撮像素子の出力にもとづいて生成された前記被写体の顔画像から目の領域を検出する初期検出部と、前記目の領域からエッジ強度画像を生成するエッジ強度画像生成部と、前記エッジ強度画像にもとづいて上瞼候補点と下瞼候補点との組を複数抽出する組抽出部と、前記複数の組のそれぞれを、左右に隣り合う組どうしの距離が近い組が同一のグループに属するようグルーピングするグループ化部と、前記グループの特徴量にもとづいて、前記被写体の瞼の開閉を判定する開閉判定部と、を備える。【選択図】 図3
