1. A diagnostic support system for analyzing human body images and displaying the analysis results, comprising:
an input interface that acquires a plurality of frame images;
a control unit that:
identifies at least one frequency of a respiratory element, which includes all or part of the exhalation or inhalation, based on the pixels of a specific region of each frame image;
detects lung fields from the acquired plurality of frame images;
divides the detected lung fields into a plurality of block regions, and calculates the image changes in the block regions for each frame image;
performs a Fourier transform on the image changes of each block region in each frame image;
extracts spectra from the Fourier transformed spectra, which are within a certain bandwidth and correspond to at least one frequency of the respiratory element, or weights specific spectra by applying coefficients;
performs an inverse Fourier transform on the spectra extracted from the certain bandwidth;
and generates images between frames based on the frequency of the respiratory element and each frame image.
