In accordance with an embodiment of the present invention, a computer system may determine focus areas and non-focus areas of the display screen. The brightness of non-focus areas may then be reduced with respect to focus areas, thereby reducing power consumption of the display screen and, hence, reducing power consumption of the computer system. For example, a focus area may be an active window of the display screen and a non-focus area may be an inactive window of the display screen. As another example, a focus area may be a region of the display screen within a vicinity of a cursor (i.e. data entry point), and a non-focus area may be the region outside this vicinity. The size of the vicinity may be measured in radius or in lines of data (e.g. in a word processing or spreadsheet program) surrounding the cursor. The size and shape of the vicinity may be determined by a user. |
