Abstract

A biological information processing device and method includes selecting image ranges of processing targets from input image data, estimating pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the selected image ranges of the processing targets, performing relative comparison between the estimated pulse rates of the processing targets and thus detecting a target which will possibly be abnormal or a target requiring special attention, and outputting information regarding the detected target which will possibly be abnormal or the detected target requiring special attention.
