A second measurement section measures a second index value that is correlated with an amount of the attention source allocated to bottom-up attention of the driver in a second area where the bottom-up attention of the driver is predominant. An estimation section estimates the driver state including an attention function degraded state of the driver on the basis of the first index value in the first area and the second index value in the second area.",
