Brightness and Contrast: Cinema Standards Measurement System (CSMS)
Specifications
-
Brightness: 119 foot-Lamberts (fL)
- Contrast Ratio: 251:1
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: 1845 ANSI Lumens
- Contrast Ratio: 251:1
These specifications are obtained by calibrating the projector
as described above for CSMS measurements.
Industry-Standard Specifications
-
Light Output: 2100 ANSI Lumens
- Contrast Ratio: 10,000:1 full-on, full-off (dynamic)
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.
