We measured the visibility of several type of chromatic text presented on a chromatic background on a liquid crystal (LC) display and extended the visibility index function (VIF) as a function of character luminance, background luminance, and character size to explain the current experimental results with a higher degree of accuracy. In addition to character luminance, background luminance, and character size, we analyzed the effect of different chromatic text and background colors under several saturation and hue conditions. The results show that the original VIF cannot predict the experimental data well under small luminance difference and large character conditions. Finally, a method was developed that showed that our improved VIF can precisely estimate the actual visibility of chromatic text presented under various conditions on a chromatic background.
