To improve accuracy in estimating attentiveness of a subject to various situations.SOLUTION: An electronic device 10 provided herein comprises an image capturing unit 11, a line-of-sight detection unit 12, and a control unit 14. The image capturing unit 11 captures and generates an image corresponding to a scene. The line-of-sight detection unit detects a line of sight of a subject with respect to the scene. The control unit 14 functions as a first estimation unit 15. The first estimation unit 15 is capable of estimating a first heat map based on the image. The control unit 14 computes the arousal level of the subject according to the first heat map and the line-of-sight of the subject. The first estimation unit 15 is constituted by machine-learned learning data of a relationship between a learning image and possible lines of sight when the arousal level of a learning subject is within a first range.SELECTED DRAWING: Figure 1

    【課題】多様な状況に対して対象者の注意力の推定精度を向上する。【解決手段】電子機器10は撮像部11と視線検知部12と制御部14とを有する。撮像部11は撮像により光景に対応する画像を生成する。視線検知部は光景に対する対象者の視線を検知する。制御部14は第1の推定部15として機能する。第1の推定部15は画像に基づいて第1のヒートマップを推定可能である。制御部14は第1のヒートマップおよび対象者の視線に基づいて対象者の覚醒度を算出する。第1の推定部15を学習用画像と学習用対象者の覚醒度が第1の範囲内である場合の視線との関係が機械学習された学習データによって構築する。【選択図】図1
