PROBLEM TO BE SOLVED: To provide a pupil and visual line measurement device capable of measuring at least either a pupil diameter or a visual line direction of a person to be measured with glasses with a high degree of precision, and an illumination system using it.SOLUTION: A pupil and visual line measurement device 8 includes an eyeball irradiation part 1 for irradiating light to eyeballs 11 of a person to be measured 10 wearing glasses 5, an optical system 2a through which reflected light from the eyeballs 11 passes, an optical system control part 2c for controlling the optical system 2a so that pupils 12 of the eyeballs 11 are in focus, but lenses of the glasses 5 are not in focus, an image pickup device 2b for receiving the reflected light passing through the optical system 2a and acquiring image data on the eyeballs 11, and an image processing part 3a for calculating at least either a pupil diameter r or a visual line direction d of the person to be measured 10 based on the image data on the eyeballs 11 acquired by the image pickup device 2b.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】眼鏡をかけた被計測者の瞳孔径および視線方向の少なくともいずれか一方を高い精度で計測することができる瞳孔・視線計測装置およびそれを用いた照明システムを提供する。【解決手段】瞳孔・視線計測装置8は、眼鏡5をかけた状態の被計測者10の眼球11に光を照射する眼球照射部1と、眼球11で反射した反射光が通過する光学系2aと、眼球11の瞳孔12にピントが合っているが、眼鏡5のレンズにピントが合っていないように、光学系2aを制御する光学系制御部2cと、光学系2aを通過した反射光を受け、眼球11の画像データを取得する撮像素子2bと、撮像素子2bによって取得された眼球11の画像データに基づいて、被計測者10の瞳孔径rおよび視線方向dのうちの少なくともいずれか一方を算出する画像処理部3aと、を備える。【選択図】図1
