Abstract: An example electronic device includes: a housing: a display including a plurality of signal lines; an optical sensor module including first and second light emitting elements respectively overlapping first and second signal lines, and a light receiving element configured to collect light from the first and/or second light emitting elements that is reflected and received from an external object; and a processor. The processor is configured to control the first light emitting element based on an off-time point of time of the first signal line corresponding to brightness of the display such that the first light emitting element emits light at a first light-emitting point of time, and to control the second light emitting element based on a time difference between off-time points of time of the first and second signal lines such that the second light emitting element emits light at a second light-emitting point of time.

Abstract: A portable electronic device includes a foldable housing; a display; an illuminance sensor; a state detection sensor; a memory; and a processor. Based on data received from the state detection sensor, the portable electronic device is recognized to be in the folded state. Responsive to the portable electronic device being in a calibration trigger state which includes the folded state, a first image is displayed in a sensor area of a first display area located on the illuminance sensor, and a second image is displayed in an area of the second display area facing the sensor area. An illuminance value is calculated based on data received from the illuminance sensor while the first image and the second image are displayed, and then compared to a reference value stored in the memory to calculate a calibration value for calibrating measured illuminance values of the illuminance sensor.

Abstract: A foldable mobile electronic device is provided. The foldable mobile electronic device includes a processor configured to recognize, based on the data received from the first sensor, a change in a state of the foldable mobile electronic device from the folded state to a partially folded state before reaching an unfolded state, to identify a first illuminance by using the data received from the second sensor, based on the recognized state change, to set a first luminance corresponding to the first illuminance as a brightness of the display, to when an angle identified after the state change falls within a predetermined first angle range or when a specific time has not elapsed after the state change, perform a real-time adjustment operation on the brightness of the display, based on a second illuminance identified using the second sensor, and to when the angle identified after the state change is outside the first angle range or when the specific time has elapsed after the state change, perform a hysteresis adjustment operation on the brightness of the display, based on the first illuminance.
