To accurately detect a head position as a viewer's posture from a relative positional relationship of the pupil position of the viewer with respect to a virtual image.SOLUTION: A projection control device includes: a projection control unit 45 for controlling the projection of a display video so that a virtual image is recognized ahead of a viewer; a video data acquisition unit 42 for acquiring a photographed video photographed by a camera 20 capable of photographing the viewer; and a detection unit 43 for detecting a posture when the viewer recognizes the virtual image based on a relative positional relationship of the pupil position of the viewer with respect to the virtual image. The projection control unit 45 controls the projection of a video for reference position determination projected to the viewer. The detection unit 43 detects the posture when the viewer recognizes the virtual image based on the relative positional relationship of the pupil position of the viewer with respect to the virtual image from the photographed video photographing the video for the reference position determination projected to the viewer, which is acquired by the video data acquisition unit 42.SELECTED DRAWING: Figure 1

    【課題】虚像に対する視認者の瞳孔位置の相対的な位置関係から視認者の姿勢として頭部位置を正確に検出すること。【解決手段】視認者の前方に虚像が視認されるように表示映像の投影を制御する投影制御部45と、視認者を撮影可能なカメラ20が撮影した撮影映像を取得する映像データ取得部42と、虚像に対する視認者の瞳孔位置の相対的な位置関係に基づいて、視認者が虚像を視認する際の姿勢を検出する検出部43と、を備え、投影制御部45は、視認者に向けて投射する基準位置判定用映像の投影を制御し、検出部43は、映像データ取得部42が取得した、視認者に投射された基準位置判定用映像を撮影した撮影映像から、虚像に対する視認者の瞳孔位置の相対的な位置関係に基づいて、視認者が虚像を視認する際の姿勢を検出する。【選択図】図1
