Device and method for acquiring heart rate

An apparatus for obtaining a heart rate, the apparatus comprising:

• one or more processors;
• and
• one or more memory devices operatively connected to the one or more processors,
• wherein the one or more memory devices include program codes, and
• wherein the program codes are executed by the one or more processors to:
• obtain a first band image and a second band image in different bands,
• measure a first remote heart rate signal and a second remote heart rate signal for the first band image and the second band image, respectively,
• compute a movement quality score, a lighting quality score, and a signal quality score for each of the first band image and the second band image,
• select a first effective heart rate section based on the first remote heart rate signal and the first quality score,
• select a second effective heart rate section based on the second remote heart rate signal and the second quality score, and
• determine a complementary heart rate based on the first effective heart rate section and the second effective heart rate section.

A method for obtaining a heart rate, the method including:

• obtaining, by a processor, a first band image and a second band image in different bands;
• measuring, by the processor, a first remote heart rate signal and a second remote heart rate signal for the first band image and the second band image, respectively;
• determining, by the processor, a first quality score and a second quality score for the first band image and the second band image, respectively;
• selecting, by the processor, a first effective heart rate section based on the first remote heart rate signal and the first quality score;
• selecting, by the processor, a second effective heart rate section based on the second remote heart rate signal and the second quality score;
• and
• determining, by the processor, a complementary heart rate based on the first effective heart rate section and the second effective heart rate section.
