A determination apparatus (14) includes: a memory (14f) memorizing a three-dimensional face model (410) in which a three-dimensional face shape and eye positions of a test subject, and change information mapping each state of change in eye shape to each shape parameter are registered； a matching unit (404) matching a picked-up image of a driver picked up by an image pickup device (201) with the three-dimensional face shape to specify the eye position； a shape parameter determination unit (405) changing the shape parameter to specify a shape parameter corresponding to the eye state in the picked-up image； an eye-opening degree calculating unit (406) calculating an eye-opening degree indicating a state of opening of the eye in the picked-up image； and a determination unit (407) determining a state of a face and an eye of the driver on the basis of the eye-opening degree and the specified shape parameter.
