<P>PROBLEM TO BE SOLVED: To provide a biological information acquisition apparatus that can select a sensor capable of acquiring optimum biological information from a plurality of sensors. <P>SOLUTION: The biological information acquisition apparatus includes: the plurality of sensors 19a-19c, 20a-20c which detect the vibration generated by a living body to output a signal corresponding the vibration; a filter processing part 12 which extracts a frequency component of biological information of a target to be acquired from the signal to output an extraction signal; a detection state determination part 14 which determines the extraction signal having the whole amplitude value being out of a predetermined range as a noise and outputs a pulse signal corresponding the noise; and a sensor evaluation/selection part 15 which outputs a new evaluation value of a sensor by adding the pulse signal to a value of multiplying a latest evaluation value of the sensor by a predetermined constant and selects the sensor for acquiring the biological information based on the new evaluation value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
