PROBLEM TO BE SOLVED: To provide a cardiac sound information processor capable of accurately detecting all characteristic parts from cardiac sound signals without omission, without being affected by noise or the like.SOLUTION: The cardiac sound information processor includes: a peak position detection part 311 for detecting a plurality of peak positions from the cardiac sound signals for which sound of the heart is collected an accuracy determination part 312 for determining whether or not the detection of the peak positions by the peak position detection part 311 is accurate and a correction processing part 313 for performing correction processing of correcting the detection of the peak positions when it is determined that the detection of the peak positions by the peak position detection part 311 is not accurate by determination by the accuracy determination part 312. The accuracy determination part 312 determines the accuracy of the peak position detection on the basis of the result of clustering the peak positions on the basis of a time length between the detected peak positions. The correction processing part 313 repeatedly executes the correction processing according to a determination result by the accuracy determination part 312.COPYRIGHT: (C)2013,JPO&INPIT【課題】ノイズ等の影響を受けることなく、心音信号から特徴的箇所を総て漏れなく正確に検出できる心音情報処理装置を提供する。【解決手段】心臓の音を採取した心音信号から複数のピーク位置を検出するピーク位置検出部311と、ピーク位置検出部311によるピーク位置の検出が正確であるか否かを判定する正確度判定部312と、正確度判定部312による判定によってピーク位置検出部311によるピーク位置の検出が正確ではないと判定された場合にピーク位置の検出を訂正する訂正処理を行う訂正処理部313と、を備える。正確度判定部312は、検出されたピーク位置同士の間の時間長に基づいてピーク位置をクラスタリングした結果に基づいてピーク位置検出の正確度を判定する。訂正処理部313は、正確度判定部312による判定結果に応じて、訂正処理を繰り返し実行する。【選択図】図1
