摘要： A method is set forth for automatically adjusting screen and/or keypad brightness on a mobile electronic device having a light sensor, display screen and keypad, for optimum legibility under varying lighting conditions, with minimal eye strain and distraction to the user. The method includes obtaining light level samples from said light sensor; and independently adjusting backlight intensity of said display screen and/or keypad responsive to said light level samples. Adjusting the backlight intensity of said display screen comprises comparing a median value of said samples to respective threshold values corresponding to screen-specific ambient lighting modes designated as 'DIM', 'OFFICE' and 'BRIGHT' modes of backlight intensity, where the screen backlight brightness for the DIM mode is less than that for the OFFICE mode which is less than that for the BRIGHT mode, and wherein said light level samples are obtained at a first sampling rate upon activation of said light sensor or in the event of a transition from said DIM mode to said OFFICE mode or said BRIGHT mode or from said OFFICE mode to said BRIGHT mode, and otherwise at a second sampling rate.

摘要： A method is set forth for automatically adjusting screen and keypad brightness on a mobile electronic device having a light sensor, display screen and keypad, for optimum legibility under varying lighting conditions, with minimal eye strain and distraction to the user. The method includes obtaining light level samples from the light sensor, and independently adjusting backlight intensity of the display screen and keypad responsive to the light level samples. Preferably, correct screen and keypad adjustments are made responsive to the user pulling his or her handheld device out of its holster notwithstanding non-optimal ambient light detection while the device is being removed from the holster. According to another aspect, the described method allows for ambient light detection in a handheld device where the light sensor and a message notification indicator share a common light pipe.
