Abstract

An organism information detecting apparatus includes a detector that detects organism information of a subject for a predetermined sampling time period, determines a motion state of the subject when the organism information is detected, and outputs an organism signal. A first calculator processes the organism signal to calculate organism information data, the detector determining a reliability degree of the organism information data based on whether the determined motion state of the subject is a previously determined motion state. A second calculator calculates an average value of the amount of variation per time of data obtained by digitizing the organism signal, the average value being data supplementary to the organism information data. The detector determines the motion state of the subject based on whether the supplementary data exceeds a previously determined threshold. A storage device stores the organism information data and the supplementary data such that the organism information data and the supplementary data are associated with one another.
