Problems solved by technology
For example, in the low-wavelength green band, accurate measurements are difficult due to the low permeability of the skin
Meanwhile, high-wavelength IR or red bands have high skin permeability but are sensitive to motion; therefore, it is difficult to perform accurate measurements through IR or red bands when the motion of the electronic device is large
Even though conventional electronic devices support various output ranges of light emitting elements, conventional electronic devices do not consider their usage status; therefore, it is difficult to accurately measure biometric information, and there is a problem of high power consumption due to the use of multiple light emitting elements

An electronic device for obtaining biological information and a method therefor are provided. The electronic device includes a biometric sensor module including a light emitting module including a first light emitting element having a first attribute and a second light emitting element having a second attribute and light receiving modules disposed adjacent to the light emitting modules, and at least one processor. The at least one processor is configured to determine a distance between the biometric sensor module and an external object based on at least reflected light reflected by collision with the external object among light output from the light emitting module, select at least one of the first light emitting element or the second light emitting element based on the distance, and obtain biometric information about the external object using the selected light emitting element.
Description
technical field [0001] The present disclosure relates to electronic devices. More particularly, the present disclosure relates to an electronic device capable of obtaining biometric information of a user when worn on the user's body. Background technique [0002] Recently, with the development of mobile communication technology and processing technology, electronic devices have changed into forms that can be easily carried while freely accessing wired or wireless networks, and functions that can be performed by electronic devices have been diversified. In addition, the form of the electronic device has been diversified, for example, the electronic device can be implemented in the form of a wearable device that can be directly attached to a part of the user's body by the user for use. A wearable electronic device may, for example, be in the form of a watch that may be attached to a user's wrist. And in this case, the electronic device may perform various functions such as t...
