Zusammenfassung:	To provide an image display device and a gaze direction detection method capable of detecting a direction of a line of sight with a simple configuration without using a light source specially.SOLUTION: An image display device 1 which is worn on the head of a person when in use includes: an image display unit 2 which faces the eyes and displays a display image; a light guide unit 5 which guides the display image to the image display unit 2; a projection unit 4 which projects the display image to the light guide unit 5; a control unit 3 which transmits the display image to the projection unit 4; an imaging unit 7 which images the eyes with visible light to obtain a corneal reflection image; and a gaze direction detection unit 8 which detects a gaze direction based on the corneal reflection image. The control unit 3 incorporates a line-of-sight detection pattern for detecting a gaze direction into a content image to generate a display image and transmits the display image to the projection unit 4. The gaze direction detection unit 8 detects the gaze direction on the basis of the corneal reflection image acquired while the line-of-sight detection pattern is displayed.SELECTED DRAWING: Figure 1 【課題】光源を特段に設けずに、簡潔な構成で視線の方向を検出することができる、画像表示装置及び視線方向検出方法を提供する。【解決手段】人間の頭部に装着されて使用される画像表示装置１であって、眼に対向して設けられ、表示画像を表示する画像表示部２と、画像表示部２へと表示画像を導光する導光部５と、表示画像を導光部５へと投影する投影部４と、表示画像を投影部４へ送信する制御部３と、眼を可視光で撮影して角膜反射画像を取得する撮影部７と、角膜反射画像を基に視線の方向を検出する視線方向検出部８と、を備え、制御部３は、視線の方向を検出するための視線検出パターンを、コンテンツ画像に混入して、表示画像を生成し、表示画像を投影部４に送信し、視線方向検出部８は、視線検出パターンが表示された状態で取得された角膜反射画像を基に、視線の方向を検出する、画像表示装置１を提供する。【選択図】図１
