PROBLEM TO BE SOLVED: To provide a gaze detection device with which it is possible to estimate the position of the pupil of one eye of a user even when the pupil of the eye is partly hidden in an image.SOLUTION: The gaze detection device comprises: an imaging unit for generating an image in which both eyes of a user are represented； and a control unit 8 having an eye detection unit 21 for detecting, for each of both eyes, an eye area from the image in which the eye is shown, a pupil detection unit 23 for detecting, for one of both eyes, a pupil area from the eye area in which the pupil is shown, an estimation unit 25 for finding an estimated shape of the pupil area in the image for the other of both eyes, a pupil redetection unit 26 for searching for an area within the pupil area for the other eye that has the estimated shape and detecting a pupil area, and a gaze detection unit 27 for detecting the direction of the gaze of the user on the basis of the position of the pupil area of each of both eyes.SELECTED DRAWING: Figure 3【課題】ユーザの一方の眼の瞳孔が画像上で部分的に隠れている場合でも、その眼の瞳孔の位置を推定できる視線検出装置を提供する。【解決手段】視線検出装置は、ユーザの両方の眼が表された画像を生成する撮像部と、画像から、両方の眼のそれぞれについてその眼が写っている眼領域を検出する眼検出部２１、両方の眼のうちの一方について眼領域から瞳孔が写っている瞳孔領域を検出する瞳孔検出部２３、一方の眼についての瞳孔領域に基づいて、両方の眼のうちの他方についての画像上での瞳孔領域の推定形状を求める推定部２５、他方の眼についての眼領域内で推定形状を持つ領域を探索して瞳孔領域を検出する瞳孔再検出部２６及び両方の眼のそれぞれの瞳孔領域の位置に基づいてユーザの視線方向を検出する視線検出部２７とを有する制御部８と、を備える。【選択図】図３
