Apparatus and method for calibration of bio-information estimation model, and bio-information estimating apparatus

An electronic device for estimating a bio-information, the electronic device comprising:

• a sensor configured to obtain a bio-signal from an object in a reference interval;
• and
• a processor configured to:
• receive an offset value measured from the object in the reference interval;
• compare the offset value with a reference bio-information value;
• in response to the offset value falling within a predetermined range compared to the reference bio-information value, determine that a condition is satisfied;
• and
• calibrate a bio-information estimation model based on the offset value and a reference feature value, based on determining that the condition is satisfied, and not calibrate the bio-information estimation model, based on determining that the condition is not satisfied.
