A method for an electronic device merges a subset of display brightness and corresponding ambient light value pairs selected from a brightness adjustment model and one or more user defined display brightness and corresponding ambient light value pairs received from user input occurring at a user interface of the electronic device to obtain a merged brightness adjustment model dataset. The method filters the merged brightness adjustment model dataset to obtain a filtered brightness adjustment model dataset and extracts a merged brightness adjustment model from the filtered brightness adjustment model dataset. One or more processors of the electronic device control a display brightness of a display of the electronic device using the merged brightness adjustment model.
