Paper Abstract
Display image quality, image reproducibility and compliance to standards are getting more and more important. It is
known that LCDs suffer from viewing angle dependency, meaning that the characteristics of the LCD change with
viewing angle.
Display calibration and corresponding quality checks typically take place for on-axis viewing. However, users typically
use their display under a rather broad range of viewing angles. Several studies have shown that when calibration is done
for on-axis viewing then the display is not accurately complying with the standard when viewing off-axis.
A possible solution is tracking the position of the user in
real-time and adapting the configuration/characteristics of the
display accordingly. In this way the user always perceives the display as being calibrated independently of the viewing
angle. However, this method requires an expensive user tracking method (such as an infrared, ultrasound or vision
based head tracking device) and is not useful for multiple concurrent users.
This paper presents another solution: instead of tracking the user and dynamically changing the behavior of the display,
we develop calibration algorithms that have inherent robustness against change of viewing angle. This new method also
has the advantage that it is a very cheap solution that does not require additional hardware such as head tracking. In
addition it also works for multiple viewers.
