Title:
HEART RATE DETECTION METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/088639
Kind Code:
A1
Abstract:
The embodiments of the present application relate to a heart rate detection method and an electronic device. The electronic device is characterized by comprising: one or more light emitters for sending at least two colors of light on a prefabricated light path; one or more light sensors for detecting light on the prefabricated light path; a processor, connected to the one or more light sensors and the one or more light emitters, and according to the relation between a feature value difference of the same feature between different colors of light of the at least two colors of light detected by the one or more light sensors and a first preset threshold, determining whether the wearing state of the electronic device is normal, when the electronic device being worn normally, performing heart rate detection. By using different colors of light to determine the wearing state of the wristband, it can be achieved to reduce the impact of a single light color on the judgment result that it is easily disturbed, after determining normal wearing, the heart rate test is performed, which improves the detection accuracy.
