Abstract
A method of adjusting color temperature of images displayed by a display system (10) whose images are based on sequential pixel data and are filtered with a color wheel (15, 15', 15'). The relative display times for each color are adjusted to result in a corresponding adjustment of color temperature. In a first embodiment (FIG. 2), the size of the color wheel's segments are changed as well as the display times for data corresponding to each segment. In a second embodiment (FIG. 3), the display times for data corresponding to one or more segments are decreased with a black display time to fill in the difference.
