Brightness and Contrast: Cinema Standards Measurement System (CSMS)
Specifications
- Brightness: 29 foot-Lamberts (fL)
- Contrast Ratio: 330:1
These measurements are taken from the projector in a controlled,
home theater environment. All measurements are made to
ANSI/NAPM IT7.228-1997 specifications using the Photo Research
PR-650 SpectraColorimeter and Minolta LS-100 Luminance Meter,
Video Essentials test DVD and a 1.3 gain, 72-inch wide screen. The
projector is calibrated to a color temperature of 6,500K and has a
minimum of 150 hours of usage.
The foot-Lambert (fL) is the unit of measurement used in commercial
movie theaters to express image brightness at the screen surface. The
Society of Motion Picture and Television Engineers (SMPTE) specifies
16 fL as the target image brightness for film-based projectors using an
open gate (without film in the projector). More importantly, today
SMPTE specifies 12 fL as the target image brightness in Digital
Cinema theaters. The foot-Lambert measurement is dependent on
screen size, screen gain and projector light output.
Home Theater Calibration Specifications
- Light Output: 450 ANSI Lumens
- Contrast Ratio: 330:1
These specifications are obtained by calibrating the projector as
described above for CSMS measurements.
Industry-Standard Specifications
- Light Output: 700 ANSI Lumens
- Contrast Ratio: 3 settings (Infinity:1, 20,000:1, 10,000:1
(sequential))
ColorContrast™
Colors have up to 50% higher contrast than Mercury or Xenon
lamp systems.
These are typical projector brightness and contrast specifications
found in most companies’ sales literature. Runco includes these
measurements in its literature to allow for direct comparison with other
manufacturers’ projectors. These measurements are typically taken at
9,000K to 13,000K to get expected performance data when the
projector is used in professional, commercial and industrial displays.
