PROBLEM TO BE SOLVED: To realize real-time and accurate detection of a pulse number of a subject having a possibility of abnormality or a subject to be a target requiring care, even in a case where surrounding environment is changed, in a manner following the change in the surrounding environment.SOLUTION: A bio-information monitoring device comprises: an image input part inputting image data of photographed n number (n: an integer of two or more) of human subjects a selection part selecting an image range of an individual subject from the input image data an estimating part estimating a pulse number of a subject corresponding to the image range based on image data within the image range of the selected individual subject a detecting part detecting a subject having a possibility of abnormality or a subject to be a target requiring care according to relative comparison of pulse numbers of n number of expected human subjects and an output part outputting information relating to the detected subject having a possibility of abnormality or a subject to be a target requiring care.SELECTED DRAWING: Figure 6
