Claims (20)

1. 1. A wearable electronic device (200) comprising:
2. a housing (210) comprising an outer housing section (211) and an inner housing section (213) connected to the outer housing section (211) and made at least partially transparent;
3. a light emitter (250) located in a housing (210) and configured to emit light through an internal section (213) of the housing;
4. a first sensor (261) located in the housing (210) and configured to receive light passing through the user's finger;
5. a second sensor (263) located in the housing (210) and configured to receive light reflected by the user's finger;
6. at least one processor (220) including processing circuitry; and
7. a memory device (230) storing instructions, wherein the instructions, when executed separately or jointly by at least one processor (220), instruct the wearable electronic device (200):
8. control the light emitter (250) to emit the first light;
9. receive through the first sensor (261) a first signal corresponding to the first light;
10. control the light emitter (250) to emit a second light;
11. receive through the second sensor (263) a second signal corresponding to the second light; and
12. generate biometric information based on the first signal or the second signal.
13. 2. The wearable electronic device of claim 1, wherein at least one piece of biometric information includes information regarding oxygen saturation or information regarding heart rate.
14. 3. A wearable electronic device according to claim 1 or 2, wherein the light emitter (250) is configured to emit light of multiple wavelength ranges, including a red wavelength and an infrared wavelength.
15. 4. A wearable electronic device according to any one of claims 1 to 3, wherein the distance between the first sensor (261) and the light emitter (250) is greater than the distance between the second sensor (263) and the light emitter (250).
16. 5. A wearable electronic device according to any one of claims 1 to 3, wherein the instructions, when executed separately or jointly by at least one processor (220), instruct the wearable electronic device (200):
17. control the light emitter (250) to emit a second light having a first intensity; and
18. control the light emitter (250) to emit a first light having a second intensity different from the first intensity after the second light is emitted.
19. 6. A wearable electronic device according to any one of claims 1 to 5, wherein the first intensity is less than the second intensity.
20. 7. The wearable electronic device of any one of claims 1 to 6, wherein the instructions, when executed individually or jointly by at least one processor (220), cause the wearable electronic device (200): at least in part based on identifying that the difference between the first signal and the second signal is less than or equal to a threshold value, to generate biometric information using the second signal.
