Abstract: According to various embodiments of the present invention, an electronic device may comprise a first sensor, a processor operably connected to the first sensor, and a memory operably connected to the processor, wherein the memory stores instructions that, when executed by the processor, cause the electronic device to: when a signal for measuring biometric information is detected, acquire depth information about a user of the electronic device from the first sensor; determine a position of a biometric reference point of the user, on the basis of the acquired depth information about the user; acquire a biometric signal relating to a measurement point of the user from the first sensor; calculate a distance between the measurement point and the biometric reference point; and correct biometric data about the user on the basis of the calculated distance and the acquired biometric signal. In addition to the various embodiments disclosed in the present invention, various other embodiments are also possible.

Abstract: An electronic device is provided. The electronic device includes a housing that includes a sensing surface, a light emitting unit that outputs a light through the sensing surface, a light receiving unit that collects a reflection light reflected from an external object in contact with the sensing surface, after the light is output from the light emitting unit, and a first Fresnel lens that is disposed between the light receiving unit and the sensing surface. A first surface of the first Fresnel lens total reflects the reflection light introduced in a direction perpendicular to the sensing surface, and a second surface of the first Fresnel lens refracts the total reflected light so as to be introduced to the light receiving unit.
