  • Intelligent automatic backlight control scheme
    Patent number: 8519938
    Abstract: A method of adjusting intensity of illumination of a device based on change in ambient light, the method comprising: measuring a first level of ambient light for a device, in response to detecting a change in ambient light; adjusting intensity of illumination for the device to a first illumination level, if an association between the first illumination level and the first level of ambient light is recorded in a data structure; monitoring user interaction with the device within a threshold period after detecting the change in ambient light to determine whether the user adjusts the intensity of illumination for the device to a second illumination level; and recording an association between the second illumination level and the first level of ambient light in the data structure.
