| description | PROBLEM TO BE SOLVED: To detect a shape of a target signal waveform from an input signal with a high degree of precision.SOLUTION: A waveform detecting device 10 acquires a signal collected by an electrocardiographic sensor 20, and creates a waveform of a polygonal line approximate to a waveform of the signal. Furthermore, the waveform detecting device 10 calculates a feature quantity of extreme points where the inclination of straight lines adjacent to each other is inverted from positive to negative or vice versa, of intersections of straight lines forming the polygonal line. Still furthermore, the waveform detecting device 10 classifies the extreme points into a convex part with a convex shape and a flat base line part, using the feature quantity of the extreme points included in the polygonal line. |
