7 June 2004Display characterization by eye: contrast ratio and discrimination throughout the grayscale
We have measured the ability of observers to estimate the contrast ratio (maximum white luminance / minimum
black or gray) of various displays and to assess luminous discrimination over the tonescale of the display. This was
done using only the computer itself and easily-distributed devices such as neutral density filters. The ultimate goal
of this work is to see how much of the characterization of a display can be performed by the ordinary user in situ, in
a manner that takes advantage of the unique abilities of the human visual system and measures visually important
aspects of the display. We discuss the relationship among contrast ratio, tone scale, display transfer function and
room lighting. These results may contribute to the development of applications that allow optimization of displays
for the situated viewer / display system without instrumentation and without indirect inferences from laboratory to
workplace.
