主权项

1. A method, comprising:
non-uniformly adjusting a brightness of at least a plurality of luminescent bodies disposed as part of a backlight of a display device based, at least in part, on one or more measurements of ambient light values determined, at least in part, by said display device; generating at least one locally adjusted brightness value for at least one of said plurality of luminescent bodies based, at least in part, on one or more sub-portion representative values filtered by at least one local weight functions; and selecting a profile for said at least one local weighting functions for filtering representative values for one or more sub-portions of said display device, wherein said profile of said one or more local weighting functions is selected based, at least in part, on said one or more measurements of ambient lights values, a contrast of said profile being increased and standard deviation of said profile being decreased with respect to an increment of the brightness of said ambient light values.
