Electronic device and method to automatically control the brightness of electronic device

An electronic device comprising:

• a display;
• a touch sensor configured to receive a user's touch input and generate touch information;
• an illuminance sensor configured to detect ambient illuminance and generate illuminance information;
• a memory configured to store brightness data relating to the ambient illuminance to brightness of the display;
• and
• a processor operatively connected to the display, the illuminance sensor, the touch sensor, and the memory,
• wherein the processor is configured to:
• identify the illuminance information from the illuminance sensor,
• configure brightness of the display as a first brightness, based on the illuminance information and the brightness data,
• change the brightness of the display to a second brightness, based on a user input,
• acquire event information for an operation in which the brightness of the display is changed by the user input,
• reconfigure the brightness data stored in the memory, based on the event information by changing brightness values mapped to illuminance values within a reference range of the illuminance information identified by the illuminance sensor, and
• determine the brightness of the display according to a brightness value in the reconfigured brightness data mapped to the illuminance information identified by the illuminance sensor.

A method of controlling brightness by an electronic device, the method comprising:

• receiving a first ambient illuminance value from an illuminance sensor;
• setting a brightness of a display as a first brightness value, based on the first ambient illuminance value and brightness data, wherein the brightness data maps ambient illuminance values to brightness values of the display;
• changing the brightness of the display to a second brightness value, based on a user input;
• reconfiguring the brightness data stored in a memory, such that the first ambient illuminance value is mapped to a third brightness value, based at least in part on the second brightness value;
• and
• set the brightness of the display according to a brightness value in the reconfigured brightness data that is mapped to a second ambient illuminance value received from the illuminance sensor.

A method of controlling brightness by an electronic device, the method comprising:

• identifying illuminance information from an illuminance sensor;
• configuring brightness of a display as a first brightness, based on the illuminance information and brightness data;
• changing the brightness of the display to a second brightness, based on a user input;
• acquiring event information for an operation in which the brightness of the display is changed by the user input;
• reconfiguring the brightness data stored in a memory, based on the event information;
• and
• determining the brightness of the display according to a brightness value in the reconfigured brightness data mapped to the illuminance information identified by the illuminance sensor,
• wherein reconfiguring of the brightness data further comprises changing brightness values mapped to illuminance values within a reference range of the illuminance information identified by the illuminance sensor.
