Claim 5:
6. The apparatus according to claim 1,
wherein the processor is further configured to execute the program to:
determine at least two principal components for each of the at least one measurement electrode of the one or more electrodes;
determine, regarding the one or more potentials corresponding to the at least two principal components, a correlation coefficient of the one or more potentials corresponding to the at least two of the principal components;
group the two principal components whose correlation coefficient is greater than or equal to a predetermined value into one group;
determine, as a contribution ratio of the one group, a sum of a plurality of contribution ratios of all of the at least one principal component included in the one group;
extract, regarding the contribution ratio of the one group and the plurality of contribution ratios of the at least one principal component that are not included in the one group, the one group and each of the at least one principal component that are not included in the one group in descending order of the contribution ratios;
estimate a sum of potentials corresponding to the at least one principal component that are included in the extracted group and in the extracted at least one principal component that are not included in the group; and
subtract the sum of the potentials from the potential of each of the at least one measurement electrode of the one or more electrodes.
