Abstract: An example electronic device may include a detection circuit and a processor operatively connected to the detection circuit. The processor may be configured to obtain a first signal associated with an external object through the detection circuit; obtain a first HR, using a first filter having an attribute of a first frequency band; obtain a second HR, using a second filter having an attribute of a second frequency band, based at least on the first signal; change at least some attributes associated with the second filter, based at least on the first HR and the second HR; obtain a second signal associated with the external object through the detection circuit; and generate heart rate variability (HRV) information, using the second filter, in which the at least some attributes are changed, based on the second signal.

Abstract: Various embodiments of the present invention relate to: an electronic device capable of measuring illuminance by using an optical sensor and providing information on the measured illuminance to a user; and an operating method therefor. The electronic device according to various embodiments of the present invention comprises: a light emitting unit; a sensor having a light receiving unit; and a processor, wherein the processor is set so as to: sense a first illuminance outside the electronic device by using the sensor; emit light by using the light emitting unit when the first illuminance belongs to a predetermined range; confirm whether an external object is nearby by using the sensor based on at least the light emitted using the light emitting unit; determine the first illuminance as the illuminance outside the electronic device when the external object is not nearby; and estimate a second illuminance corresponding to the first illuminance by using a selected method based on at least context information related to the electronic device when the external object is nearby.
