Brightness and Contrast: Cinema Standards Measurement System (CSMS)
Specifications
- Brightness: 58.3 foot-Lamberts (fL)
- Contrast Ratio: 320:1
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: 1380 ANSI Lumens
- Contrast Ratio: 320:1
These specifications are obtained by calibrating the projector as
described above for CSMS measurements.
Industry-Standard Specifications
- Light Output: 2825 ANSI Lumens
- Contrast Ratio: 4000:1
These are typical projector brightness and contrast specifications found
in most companies’ sales literature. Vidikron 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.
