Abstract: A method of measuring biological information according to the present disclosure is a measurement method of measuring biological information from a frame image group obtained by imaging over time of a subject. The method of measuring biological information according to the present disclosure divides a target region in each frame image included in the frame image group into a plurality of sub regions and extracts an amount of variation in each of the plurality of sub regions from the frame image group. The method of measuring biological information then determines sub regions similar in amount of variation from among the plurality of sub regions and obtains the biological information of the subject based on a summed value of the amount of variation in each of the similar sub regions.
