1. A method for measuring a temperature in an electronic device including an infrared (IR) sensor and a temperature sensor, the method comprising:
- emitting, by using the IR sensor, an IR light in response to receiving an input for measuring a temperature of an object;
receiving, by using the IR sensor, a light reflected from the object, the light being a reflected light of the IR light;
measuring an amount of the light reflected from the object;
determining a distance between the object and the IR sensor, based on the measured amount of the light;
determining a size of a region for measuring a temperature of the object based on the determined distance and a predetermined distance between the IR sensor and the temperature sensor;
determining whether the determined size of the region is different from a preset size; and
outputting a temperature measurement guide message, in response to determining that the determined size of the region is different from the preset size.

Abstract
An apparatus and method for measuring a temperature in an electronic device. An amount of light of an optical signal reflected off of an object is measured, and a size of a temperature measurement expectation area on the object based is determined based on the measured amount of light. A temperature measurement guide message is output based on a result of comparing the determined size and a reference area.
