5. A laughter analysis device configured to:
acquire, by an imaging unit, at least a first facial surface position corresponding to a root portion, on an eye side of a subject, of a zygomaticus major muscle of the subject, and a plurality of second facial surface positions corresponding to portions other than the root portion of the zygomaticus major muscle on at least one of left and right sides of a face of the subject;
based on setting the first facial surface position as a first reference position and setting each of the second facial surface positions as a second reference position, calculate each of displacements between the second reference position and the first reference position in a predetermined time cycle, and sum up the calculated displacements for every predetermined time cycle to calculate a first feature quantity; and
calculate a laughter-related emotion analysis value of the subject based on the first feature quantity.
