Table 7-1. Vision 50 Specifications (continued)

Brightness and Contrast:

Cinema Standards Measurement System (CSMS)

 

Specifications

 

-

Brightness*: 14.7 to 21.5 foot-Lamberts (fL)

 

-

Contrast Ratio*: 195:1 to 218:1

 

*Variable depending on Aperture Control setting

 

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: 449 to 585 ANSI Lumens

 

-

Contrast Ratio*: 195:1 to 218:1

 

These specifications are obtained by calibrating the projector as

 

described above for CSMS measurements.

 

Industry-Standard Specifications

 

-

Light Output: 1225 ANSI Lumens

 

-

Contrast Ratio: 1400:1 to 3000:1

 

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.
