Imaging analyzer

An imaging analyzer capable of acquiring spectral data by executing predetermined analysis on each of a plurality of micro areas set in a two-dimensional measurement region on a sample or a three-dimensional measurement region in a sample, the imaging analyzer comprising:

• a clustering execution section configured to execute clustering processing of classifying spectral data for a plurality of measurement points obtained for one sample into any of a plurality of clusters;
• a segmentation image creation section configured to create a segmentation image obtained by partitioning the entire two-dimensional or three-dimensional measurement region or a part of the entire two-dimensional or three-dimensional measurement region into a plurality of small regions on the basis of a result of the clustering processing;
• and
• a region-of-interest designation accepting section that displays the segmentation image on a display unit and recognizes one or a plurality of partitioned small regions in the segmentation image as a region of interest according to an operation of an input unit by a user.
