| abstract | (57) Abstract: An abnormality of a lighting unit in a line-of-sight detection unit is detected and a user is informed of the abnormality. SOLUTION: An illumination means for illuminating an eyeball of a user or a subject, a light receiving means for receiving an eyeball image of the user, and a signal processing means for processing an eyeball image signal output by the light receiving means are provided. In the visual line detection device for extracting the characteristic points of the eyeball image to detect the visual line of the user, the visual line detection device has an abnormality detection unit that detects an abnormal operation of the illumination unit. |
