Abstract
A method and a device are provided. The device includes a light-measuring sensor, a display, a memory, and at least one processor operatively connected to the light-measuring sensor, the display, and the memory, wherein the at least one processor is configured to analyze the frequency of an external light source, obtain an operation period of the display, obtain a ratio of an off period of time of the display on the basis of the operation period, and calculate illuminance by using different algorithms on the basis of the relationship between the frequency of the external light source and the operation period and the ratio of the off period of time of the display.
