US 12,594,039 B2 · Electronic device and method for correcting biometric data on basis of distance between electronic device and user, measured using at least one sensor

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.

An electronic device, comprising:

a depth sensor;
a biometric sensor;
memory storing instructions;
and
a processor,
wherein the instructions, when executed by the processor, cause the electronic device to:
detect a signal for measuring biometric information,
obtain, in response to the signal, depth information of a user of the electronic device from the depth sensor, wherein the depth information includes information for at least one of a location of a face, eyes, nose, mouth, or upper body of the user,
