TRUE WHITE FOR TELEVISIONS
This study proposes the optimal white point settings of consumer televisions observed in different viewing conditions. The ratings from visual experiments were modeled with a bivariate Gaussian distribution to predict the optimal white points. The results indicated that current white point settings of major television manufacturers are too bluish. Neither televisions that meet the current standards nor televisions in the market would appear as true white under the viewing conditions employed in this study. Moreover, the research proposed to automatically change the white point of the display based on the image content and the real-time measurements of the surrounding ambient light falling on the screen. Ultimately, this study might be of interest to the industry as a basis for future deliberations on target white points for consumer televisions designed to provide a better color appearance.
