A section in which a motion for adjusting the posture of a living body or an object is identified accurately. An information processing device (101) extracts a main motion section (111) and an adjustment motion section candidate (112) from an acquiring sensor (102) as illustrated in (1) to (3) of FIG. 1 . Next, the information processing device (101) calculates a relationship likelihood value that the adjustment motion section candidate (112) is an adjustment motion section for the main motion section (111) based on the feature amount of the main motion section (111) and the feature amount of the adjustment motion section candidate (112) as illustrated in (4) of FIG. 1 . Then, the information processing device (101) determines whether the adjustment motion section candidate (112) is an adjustment motion section for the main motion section (111) based on the calculated relationship likelihood value as illustrated in (5) of FIG. 1 .

A pulse wave analyzing apparatus (100) acquires a moving image (101) obtained by photographing a subject. The pulse wave analyzing apparatus (100) extracts images of each part of a plurality of parts of the subject from each of the photographed images included in the acquired moving image (101). The pulse wave analyzing apparatus (100) generates pulse wave waveforms of each of the parts by analyzing the images of each of the parts extracted from each of the photographed images. The pulse wave analyzing apparatus (100) calculates a matching degree between the generated pulse wave waveforms of each of the parts. The pulse wave analyzing apparatus (100) outputs the calculated matching degree as an index value indicating likelihood of pulse wave in the pulse wave waveform of the subject.
