Abstract
Provided is an electronic device. The electronic device includes a housing that includes a front side and a back side, a display, an illuminance sensor overlapping at least one active area of the display in a top view from above the front side, at least one processor, and a memory. The memory stores instructions that, when executed, cause the at least one processor, while the display is in operation, to change a brightness of a screen displayed on the display, to identify display parameter information associated with the changed brightness, to set a measuring time of the illuminance sensor, based at least partially on the identified display parameter information, to acquire raw data measured during the measuring time by the illuminance sensor at a specified period, to generate intermediate data using the acquired raw data, and to calculate an illuminance value using the generated intermediate data.
