A pattern reading system by line segment approximation comprising the steps of tracing the contour and simultaneously, seeking out as candidate extreme points the points at which the inner products of coordinate point vectors and directional vectors at coordinate points of the contour being traced are largest, and feeding out these candidate extreme points as real extreme points when the differences between the inner products of the direction vectors and the inner products of the candidate extreme points are greater than an allowance set in advance.
