Abstract
An object is to provide a biological signal processing device capable of evaluating the reliability of the measurement state of a biological signal, based on RRI information. A biological signal processing device includes: an RRI information acquisition means for acquiring RRI information composed of RRIs, of a biological signal measured by a sensor, arranged in time series, from the sensor; a map generation means for plotting points whose positions are determined based on values of the RRIs constituting the RRI information, on a feature space, and generating a map from the feature space; an index calculation means for calculating an index indicating resemblance to heart rate variability of each RRI constituting RRI information to be evaluated; and a reliability calculation means for calculating RRI reliability of each RRI constituting the RRI information, from the index.
