摘要

PPROBLEM TO BE SOLVED: To provide an outline detection apparatus that can compute an accurate outline shape with less computational complexity irrespective of the outline shape. PSOLUTION: An outline detection means 2 detects a plurality of temporary outline data from an image captured by an imaging device 1. As regarding the plurality of temporary outline data detected by the outline detection means 2 as a population, an arithmetic means 3 detects the dispersion of a plurality of first distances between the plurality of temporary outline data and the centroid of the population, and computes a plurality of second distances between the centroid of the detected dispersion and the plurality of temporary outline data, and also the average of the plurality of second distances. With the plurality of second distances and the average of the plurality of second distances computed by the arithmetic means 3, a determination means 4 removes temporary outline data whose second distance relatively deviates from the average of the plurality of second distances as false outline data from the plurality of temporary outline data to provide true outline data.
