Abstract
A method of detecting and compensating for colors displayed by a display system (10) that uses a light source (16) and a color wheel (15). A desired color balance is specified in terms of a power ratio of three primary colors. This ratio is then compared to the actual power of light filtered through each color of the color wheel. (FIGS. 2A, 2B). In a first embodiment, the filter transmission characteristics are adjusted. (FIG. 3). In a second embodiment, the size of the color wheel's segments are changed as well as the display times for data corresponding to each segment. (FIG. 4). The two embodiments can also be combined to achieve a desired color balance.
