Apparatus and method for monitoring bio-signal measuring condition, and apparatus and method for measuring bio-information

A method for monitoring a bio-signal measuring condition, the method comprising:

• receiving a bio-signal that is measured from a user;
• extracting any one or any combination of a waveform feature, a period feature, and an amplitude feature, from the received bio-signal;
• determining whether the extracted any one or any combination of the waveform feature, the period feature, and the amplitude feature are normal, using a predetermined determination reference corresponding to the extracted any one or any combination of the waveform feature, the period feature, and the amplitude features;
• and
• monitoring a measuring condition of the received bio-signal, based on whether the extracted any one or any combination of the waveform feature, the period feature, and the amplitude feature are determined to be normal.

An apparatus for measuring bio-information, the apparatus comprising:

• a bio-signal measurer configured to measure a bio-signal by emitting a first light onto an object and receiving a second light that is reflected from the object onto which the first light is emitted;
• a processor configured to:
• extract one or more features, from the measured bio-signal;
• monitor a measuring condition of the measured bio-signal, using at least one predetermined determination reference corresponding to the extracted one or more features;
• and
• perform a pre-defined operation, based on the monitored measuring condition;
• and
• an output part configured to output a processing result of the processor, on a display.

• a bio-signal receiver configured to receive a bio-signal that is measured from a user;
• and
• a processor configured to:
• extract a waveform, a period, and an amplitude, from the received bio-signal;
• determine whether the extracted waveform is normal by comparing the extracted waveform to a reference waveform;
• determine whether the extracted amplitude is normal by comparing the extracted amplitude to a reference amplitude;
• determine whether the extracted period is normal by comparing the extracted period to a reference period;
• based on the extracted amplitude being determined to be abnormal, control to output any one or any combination of an inadequate contact pressure condition, an ambient light noise condition, and a condition of not measuring the bio-signal;
• based on one of the extracted period and the extracted waveform being determined to be abnormal, control to output any one or any combination of a motion noise condition, a condition of cardiac arrhythmia, and a contact failure condition;
• and
• based on the extracted amplitude, the extracted period, and the extracted waveform being determined to be normal, control to output a normal measuring condition.
