Conventional displays use at least three primaries for full colour image reproduction. In this contribution, we discuss the reproduction of colour images using an LC-display system with two local dynamic primaries, based on a segmented backlight. The two primaries are chosen to minimise colour error by means of total least squares. By considering video statistics, it is shown that full colour repreoduction with an accuracy of Δu′v′ < 0:02 for more than 99.9% of the pixels in a segment can be achieved 84% of the time with 2,304 semgments. Simulation results show that two-primary systems can closely resemble colour reproduction of a conventional three-primary system.

  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, and a vibrant interactive papers session. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper presentation.
