Abstract: A prediction device includes a state detector that detects a state related to sleepiness of a driver; an eye-closure duration detector that detects an eye-closure duration of the driver; and a microsleep predictor that predicts that the driver is in the microsleep state, on conditions that the state detector detects the state related to the sleepiness of the driver and that the eye-closure duration detector detects the eye-closure duration that is no shorter than a first duration and no longer than a second duration.

Abstract: An estimation apparatus includes: an image information obtainer that obtains image information of a captured image of a driver; a first detector that detects face information indicating facial behavior of the driver, based on the image information; a first reliability calculator that calculates first reliability; a second detector that detects body information indicating body movement of the driver, based on the image information; a second reliability calculator that calculates second reliability; a weight setter that, when the face information and the body information are detected, sets a first weight corresponding to the face information and a second weight corresponding to the body information based on the first reliability and the second reliability; and an estimator that estimates drowsiness of the driver based on the face information weighted by the first weight and the body information weighted by the second weight.
