PROBLEM TO BE SOLVED: To provide a biological information analysis device capable of efficiently processing measurement data in which there is a blank point having no measured value, for identifying a state of a subject.SOLUTION: A signal processing device functions as a biological information analysis device for analyzing biological information of a user U who is a subject and identifying a state of the user U. Measurement data InD acquired by the signal processing device is configured so that plural measurement points DP having a measured value and plural blank points BP having no measured value are arranged. The signal processing device extracts a feature which is effective for identifying a state of the user U from the measurement data InD by convolution calculation for moving a filter Fi1 which is regulated to a shape overlapped to the measurement points DP while avoiding the blank points BP, to the measurement data InD and applying the filter to individual measured value sequentially.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】計測値のない空白点が存在する計測データを効率的に処理して、被験者の状態を識別することが可能な生体情報の解析装置の提供。【解決手段】信号処理装置は、被験者であるユーザUの生体情報を解析し、ユーザUの状態を識別する生体情報解析装置として機能する。信号処理装置の取得する計測データInDは、計測値のある計測点DPと計測値のない空白点BPとがそれぞれ複数ずつ配列されてなる。信号処理装置は、空白点BPを避けつつ計測点DPと重なる形状に規定されたフィルタFi1を、計測データInDに対して移動させつつ個々の計測値に順に適用する畳み込み演算により、ユーザUの状態の識別に有効な特徴を、計測データInDから抽出する。【選択図】図3
