Abstract
An electronic device includes one or more optical transmitters, configured to send lights of at least two colors on a preset optical path, one or more optical sensors, configured to detect the lights on the preset optical path, and a processor, configured to determine whether a wearing status of the electronic device is normal, based on a relationship between a first preset threshold and an eigenvalue difference between same features of lights of different colors in the lights of at least two colors that are detected by the one or more optical sensors, and detect a heart rate when the electronic device is worn normally.

1-23. (canceled)
An electronic device for detecting a heart rate, comprising:
- one or more optical transmitters configured to send a first plurality of lights of at least two colors on a first preset optical path;
- one or more optical sensors configured to detect the first lights on the first preset optical path;
- and
- a processor coupled to the one or more optical sensors and the one or more optical transmitters and configured to:
- determine whether a wearing status of the electronic device is normal based on a first relationship between a first preset threshold and a first eigenvalue difference between same features of a second plurality of lights of different colors in the first lights;
- and
- detect the heart rate when the wearing status is normal.
A method for detecting a heart rate, comprising:
- sending a first plurality of lights of at least two colors on a first preset optical path;
- detecting the first lights;
- determining whether a wearing status of an electronic device is normal based on a first relationship between a first preset threshold and a first eigenvalue difference between same features of a second plurality of lights of different colors in the first lights;
- and
- detecting the heart rate when the wearing status is normal.
A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause an information processing apparatus to:
- send a first plurality of lights of at least two colors on a preset optical path;
- detect the first lights;
- determine whether a wearing status of an electronic device is normal based on a first relationship between a first preset threshold and a first eigenvalue difference between same features of a second plurality of lights of different colors in the first lights;
- and
- detect a heart rate when the wearing status is normal.
