Abstract: A looking away determination device includes: a determination unit that determines that a driver is in a looking away state when a proportion of an image in which a face of the driver is not detected with respect to a plurality of images obtained by imaging the driver is equal to or greater than a first predetermined value, the first predetermined value being determined based on driving state information that indicates a state during driving by the driver.

Abstract: A looking away determination device includes: a looking away determination unit that determines that a driver is in a looking away state when a proportion of an image in which a face having a degree of certainty equal to or greater than a threshold value is shown with respect to a plurality of images obtained by imaging the driver, the degree of certainty serving as an index of face likeness; and an updating unit that updates the threshold value based on a degree of certainty of a face shown in an image obtained by imaging the driver.

Abstract: A driving-state monitoring system includes a driving-state monitoring device and a driving-state sensing device. The driving-state sensing device captures an image of a driver of a vehicle to thereby generate driving-state data. The driving-state monitoring device acquires the driving-state data and the captured image of a driver of a vehicle from the driving-state sensing device. An authentication process is made to determine whether or not a driver matches a pre-registered driver based on the information of a driver included in the captured image, thus determining the identification information of the driver successfully authenticated. The driving-state data is recorded on a database in association with the identification information of the driver. Accordingly, it is possible for the driving-state monitoring device to monitor a plurality of vehicles using a plurality of driving-state sensing devices, thus precisely managing a plurality of vehicles in terms of their driving states.
