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: Disclosed is an electronic device including a processor configured to set a wake-up luminance of a display, based on a wake-up illuminance, to set, upon detecting an illuminance change through the illuminance sensor, a first target luminance of the display by using a first threshold illuminance value at a time point of detecting the illuminance change, to identify whether a flag setting related to an update of a threshold illuminance value is changed, while changing a luminance of the display based on the first target luminance, to determine the first target luminance as a final luminance of the display when there is no change in the flag setting, to update the first threshold illuminance value to a second threshold illuminance value when there is a change in the flag setting, and to change a target luminance of the display from the first target luminance to a second target luminance by using the second threshold illuminance value.

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.

Abstract: An electronic device and method utilizes an external sensor group to facilitate miniaturization the device and repair/replacement of external sensors. An interface connected to an external sensor package including at least one sensor. A processor that when the external sensor package is connected through the interface, determines from which group the external sensor package is included in among pre-configured groups and controls the performance of a function corresponding to the determined group.
