Abstract
A driver abnormality sign detection device includes a control circuit configured to detect an abnormality sign of a driver based on visual line information acquired from a visual line detector and on image data from a vehicle-outside camera. The control circuit is configured to acquire reference saccades of the driver, calculate dispersion of a section including a peak of saliency in a visual field of the driver based on the image data, calculate predicted saccades by correcting the reference saccades with correction values acquired based on the dispersion of the section including the peak of the saliency, and detect presence or absence of the abnormality sign of the driver based on a visual line abnormality degree representing an extent that measured saccades diverge from the predicted saccades.
