ELECTRONIC APPARATUS AND CONTROL METHOD

摘要

According to one embodiment, a wearable electronic apparatus detects movement of a human body wearing the apparatus. The apparatus causes a first number of light emitters to emit light when a magnitude of the detected movement is less than a first value. The first number of light emitters is among a plurality of light emitters which emit light having different wavelengths, in which the light are received by a light receiver to obtain physiological information. The apparatus causes a second number greater than the first number of light emitters among the plurality of light emitters to emit light when the magnitude of the detected movement is greater than or equal to the first value.

主权项

1. A wearable electronic apparatus, comprising:
a plurality of light emitters to emit light having different wavelengths; a light receiver to receive reflected light or transmitted light emitted from the light emitters, the reflected light from a human body wearing the apparatus, the transmitted light passing through the human body; an acquisition processor to acquire physiological information on the human body wearing the apparatus based on the reflected light or the transmitted light received by the light receiver; a sensor to detect movement of the human body wearing the apparatus; and a controller to cause a first number of the light emitters to emit light when a magnitude of the movement detected by the sensor is less than a first value, and to cause a second number greater than the first number of the light emitters to emit light when the magnitude of the movement detected by the sensor is greater than or equal to the first value, the light emitters of the second number comprising the light emitters of the first number.
