Abstract

In order to provide a biological information detection apparatus capable of minimizing omission and errors in detecting a biological signal, a biological information detection apparatus is provided with: a plurality of detection units arranged on a support for supporting a living body, and adapted for outputting signals corresponding to vibration of the living body to be detected; extraction units for extracting signals in a predetermined frequency range corresponding to vibration of the living body to be detected; a timing detection unit for detecting a vibration timing of individual feature points from the signals extracted by each of the extraction units; a timing storage unit for storing a storage vibration timing that is the vibration timing detected by the timing detection unit; a determination unit for determining whether or not the detection vibration timing conforms to the stored vibration timing; and a timing output unit for outputting, as biological information about the living body, detection vibration timing in a case where the detection vibration timing conforms to the stored vibration timing.

Claims

a plurality of detection units arranged on a support for supporting a living body, and adapted for outputting signals that correspond to vibration to be detected;

extraction units for extracting signals in a predetermined frequency range for the signals outputted from each of the detection units, the extracted signals corresponding to vibration of the living body to be detected;

a timing detection unit for detecting, as a detection vibration timing, a vibration timing of individual feature points from the signals extracted by each of the extraction units;

a timing storage unit for storing, as a stored vibration timing, the detection vibration timing detected by the timing detection unit;

a determination unit for determining whether or not the detection vibration timing conforms to the stored vibration timing; and

a timing output unit for outputting, as biological information about the living body, the detection vibration timing detected for at least one detection unit in a case where the detection vibration timing conforms to the stored vibration timing.

2. The biological information detection apparatus of claim 1 further comprising a timing update unit for updating the stored vibration timing in accordance with the detection vibration timing detected by the timing detection unit.

3. The biological information detection apparatus of claim 2, the timing update unit updating the stored vibration timing in accordance with a plurality of the detection vibration timings when the feature points of the plurality of the detection vibration timings are within a predetermined range, for each of the detection vibration timings detected by the timing detection unit.
