Bio-information output device, bio-information output method and program
The reliability of calculated bio-information of a subject is determined. When the reliability of the bio-information is determined to be high, the bio-information is output, whereas when the reliability of the bio-information is determined to be low, the bio-information is not output. Thus, among the calculated bio-information, only the bio-information of high reliability may be output, or distinctive display may be performed depending on the reliability, whereby it is possible to provide a bio-information output device and the like capable of easily determining bio-information of high reliability.
