Abstract:
1. A method, comprising: accessing a plurality of values representing a light spreading profile for a particular luminescent body, wherein said particular luminescent body is disposed as part of a side emitting backlight of a display device, and wherein said light spreading profile is operable for showing light distribution characteristics of light emitted from said particular luminescent body; determining a brightness value associated with said particular luminescent body by filtering one or more image characteristic values of an input image through at least one light spreading profile weighting function determined based, at least in part, on said plurality of accessed values representing said light spreading profile, said light spreading profile being used to determine a backlight level for said particular luminescent body; controlling said brightness value associated with said particular luminescent body based on said determined brightness value associated with said particular luminescent body; determining a truncated area of an input image according to a predetermined percentage of intensity value of said light spreading profile of said particular luminescent body; dividing said input image within said truncated area into a plurality of sub-image blocks; determining a plurality of representative values associated with said plurality of sub-image blocks; determining said brightness value associated with said particular luminescent body according to said plurality of representative values and said light spreading profile, said determining said brightness value associated with said particular luminescent body comprising;
