New Color Brightness Metric Solves Projector Color Evaluation Problem

Amsterdam, Netherlands (ots/PRNewswire) -

3LCD today confirmed its support for the new Color Brightness
metric. The Color Brightness metric is being submitted to the ISO
for approval as an update to the International Standard for light
output measurement. Color Brightness specifies a projector's ability
to deliver color. The Color Brightness metric addresses the failure
of current projector specifications to measure color performance,
allowing purchasers to evaluate color performance at a glance. 3LCD
joins a growing list of industry players supporting the new metric.

Today all video, DVD, HD, digital camera and computer signals are
encoded in an RGB color space. In all of these devices and in the
world around us, red, green and blue added together equal white. If
this is not the case, a full and balanced range of color cannot be
reproduced. Color Brightness measures the brightness of red, green
and blue, just like the input signal. If a projector can produce
bright red, green and blue that combined equal the brightness of
white, true, accurate and balanced color is possible. If Color
Brightness does not equal the White Brightness, accurate color
reproduction is impossible.

Karl Lang, chief color scientist at Lumita said: "the projector
product landscape has wide variation in color performance at all
price points. To most end-users color performance is unclear and
difficult to evaluate until after purchase. Many projectors have
significant undocumented defects in color performance, it's
impossible for consumers to fairly evaluate a projector purchase
based on the existing specification metrics. Given the costs of
projectors, and the dizzying array of models, it's high-time for the
industry to adopt Color Brightness and to provide end-users with a
simple metric that follows existing methodology. The addition of this
metric will require no change to existing product qualification
procedures."

Other industry experts and market specialists agree with the
proposal. "This proposal makes a lot of sense, especially given the
number of expensive projectors we have tested that can't even
accurately reproduce sRGB," said Steve Upton, CEO of Chromix.
"Consumers expect a projector to reproduce color at least as well as
a cheap display and they don't find out it can't until after the
purchase. The methodology of this spec is firmly rooted in existing
standards and prevents companies from hiding poor color performance."

The new proposal modifies the International Standard IEC 61947-1
to provide purchasers with additional information on a projector's
color performance. The existing brightness standard provides
consumers and purchasing managers a critical metric often
communicated as "lumens" or "ANSI lumens." The updated specification
will not affect this current white illuminance measurement. It simply
adds another metric that specifically measures color illuminance.
Color Brightness is measured using the same industry-standard
methodology. The new number is also reported in lumens, providing a
familiar and relative number. If both the white illuminance
(brightness) and color illuminance (color brightness) are equal, the
projector will accurately deliver the proper energy to the primary
colors of red, green and blue exactly as they are in the source video
signal.

Studies are underway around the world to confirm the utility of
this new metric. The first such study was presented November 6th,
2007 at the 15th Color Imaging Conference in Albuquerque, NM.
