Summary:An apparatus for emotion estimation sets a face feature threshold based on a plurality of face features indicating a deviation from a reference state of a predetermined part of a face detected from each of a plurality of face images representing a face of a driver of a vehicle generated by a camera mounted on the vehicle in a predetermined time range, specifies face features larger than the face feature threshold among the plurality of face features detected from each of the face images generated by the camera at a time not included in the predetermined time range, and estimates an emotion of the driver by using normalized features obtained by normalizing the specified face features downward.
