Abstract
There is disclosed an apparatus and method for highlighting one or more selected portions of a display screen. The apparatus comprises a color shift controller capable of receiving a user input selecting one of a plurality of portions of a display screen and, in response to the user input selection, modifying the value of the pixels within the selected portion to increase the color temperature of the pixels. The method comprises selecting a portion of the display screen and increasing the color temperature of at least one color within the selected portion of the display screen. In one advantageous embodiment of the present invention, the color shift controller modifies white color pixel values in a selected portion of the display screen to new white color pixel values that have a higher color temperature. The higher color temperatures increase the apparent brightness of the displayed images.
