ABSTRACT:
A display brightness monitoring system associates a brightness level and an ambient light level with a user identifier. Ambient light signals are received from an ambient light sensor mounted in proximity of an electronic display. Brightness levels are received from a brightness control mechanism for user selection of a display brightness. The monitoring system collects brightness levels and associates them with one of the ambient light levels associated with a user identifier. Preferably, a plurality of brightness levels are collected for each ambient light level and are used to compute a preferred brightness level indicative of a user's preferred display brightness for a given ambient light level. The brightness levels may be statistically averaged for computation of the brightness level. A data structure for associating brightness levels with ambient light levels and associating ambient light levels with a user identifier may be used to segregate one user's brightness levels from those of another. In this manner, the display may be driven using the preferred brightness levels for the user authorized to use a computer without altering the brightness levels stored for other users.
