Abstract
A direction discrimination device includes: an extraction unit configured to extract pieces of feature information from an image of a person, each of the pieces of feature information representing a feature of corresponding one of portions of the person; and a discrimination unit configured to discriminate a direction of the person based on the pieces of feature information. The discrimination unit is configured to weight first feature information which is feature information of a portion that is likely to have a difference in the feature between a first direction and a second direction range, more than second feature information which is feature information of a portion that is less likely to have a difference, in determination of the direction of the person. The second direction range not includes the first direction and includes a second direction opposite to the first direction.
