1. A distracted-driving monitoring apparatus for a vehicle, the distracted-driving monitoring apparatus comprising:
an imaging device configured to capture an image of at least one occupant of the vehicle; and
a determiner configured to make a determination on distracted driving of the occupant of the vehicle based on the captured image, wherein
the determiner is configured to:
identify areas in the captured image corresponding to areas that the occupant faces from among divided areas obtained by dividing a viewing range, the viewing range corresponding to a range where the occupant is likely to face while the vehicle is in operation;
the determiner is configured to execute determination processing differently for each of the identified areas to make the determination on the distracted driving of the occupant,
the determiner is further configured to:
identify, from the captured image, an eye direction of the occupant and a face direction of the occupant;
for a first area among the divided areas obtained by dividing the viewing range, make a determination on the distracted driving of the occupant by using both of the identified face direction and the identified eye direction;
for a second area among the divided areas obtained by dividing the viewing range, make a determination on the distracted driving of the occupant not by using the identified face direction but by using the identified eye direction, the second area being different from the first area; and
for a third area among the divided areas obtained by dividing the viewing range, make a determination on the distracted driving of the occupant not by using the identified eye direction but by using the identified face direction, the third area being other than the first and second areas.
