1. A driver management apparatus for managing a driver of a vehicle, the apparatus being capable of exchanging various data sets with an external center, the apparatus comprising: a sensing means for sensing the driver; a sensing information storing means for temporarily storing the sensing information that is a result of the sensing of the driver provided by the sensing means; a state estimating means for estimating a state of the driver based on the sensing information; an extracting means for extracting, as a capture region, part of the sensing information, which is stored by the sensing information storing means, based on an estimation result provided by the state estimating means; a capture information storing means for extracting the sensing information, which is associated with the capture region extracted by the extracting means, from the sensing information storing means, and for storing the extracted sensing information as capture information; a determining means for determining whether the estimation result provided by the state estimating means satisfies a reporting condition for determining that the external center is to be informed of the estimation result; and a controlling means for retrieving the capture information, which is associated with the estimation result, from the capture information storing means, and for causing the retrieved capture information to be transmitted with the estimation result to the external center when the determining means determines that the estimation result satisfies the reporting condition.
