The device has unit space design means for designing one or more unit spaces by a feature value generated from the input signal corresponding to one or multiple preset reference conditions concerning the presence or absence of the generation of the biological signal, separation degree calculation means for calculating one or more separation degrees being the degrees separated from the unit space in the input signal of a determination target based on the feature value generated from the input signal of the determination target, and signal generation determination means for determining the generation of the biological signal in the input signal of the determination target based on the calculated separation degrees. Here, it is preferable that at least the unit space concerning the reference conditions of biological signal generation may be designed. Also, it is preferable that the feature value may contain an amplitude component and a component concerning a period of the input signal.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】信号処理の計算量の増大を抑制しつつ、検知対象である生体信号の発生をより精度良く判定可能な装置を提供する。【解決手段】本装置は、生体信号を含み得る入力信号を処理する生体信号処理装置であって、生体信号の発生の有無に係る１つ又は複数の予め設定された基準状態に該当する入力信号から生成された特徴量によって１つ又は複数の単位空間を設計する単位空間設計手段と、判定対象の入力信号から生成された特徴量に基づいて、判定対象の入力信号における単位空間から離隔した度合いである１つ又は複数の離隔度合いを算出する離隔度合い算出手段と、算出された離隔度合いに基づいて、判定対象の入力信号における生体信号の発生を判定する信号発生判定手段とを有する。ここで、少なくとも生体信号発生の基準状態に係る単位空間が設計されることも好ましい。また、上記の特徴量は、入力信号の振幅成分及び周期に係る成分を含むことも好ましい。【選択図】図３
