Patent ID: 8514167

Claim:
A method, comprising: generating one or more electrical signal values corresponding to one or more luminescent bodies of at least a portion of a backlight of a display device to adjust a brightness level associated with said at least a portion of said backlight, said generating one or more signal values comprising: generating a plurality of image sub-portions from an input image; selecting a group of image sub-portions related to a particular luminescent body of said portion selected from said plurality of image sub-portions; determining at least one intra-frame value for said particular luminescent body, said at least one intra-frame value being determined based, at least in part, on a plurality of representative signal values associated with said selected group of image sub-portions; and determining one or more weight values associated with said one or more representative signal values, wherein said one or more weight values are based, at least in part, on a distance from one or more of said image sub-portions to said particular luminescent body, said at least one intra-frame value being determined as a function of said one or more calculated representative signal values and said one or more weight values, wherein at least one intra-frame value is determined to be equal to Max(weight value i *representative signal value i ) iεI, wherein I represents the number of said selected image sub-portions, wherein at least a first selected group of image sub-portions overlaps at least a second selected group of image sub-portions.
