<P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
