Table 7-1. VX-44d/-55d Specifications (continued)

Brightness and Contrast:

Cinema Standards Measurement System (CSMS)

 

Specifications

 

-

Brightness: 86.0 foot-Lamberts (fL) (VX-44d);

 

 

107.3 fL (VX-55d)

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

233:1 - 285:1 (VX-44d);

 

 

229:1 - 279:1 (VX-55d)

 

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:

 

 

2180 ANSI Lumens (VX-44d);

 

 

3462 ANSI Lumens (VX-55d)

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

233:1 - 285:1 (VX-44d);

 

 

229:1 - 279:1 (VX-55d)

 

These specifications are obtained by calibrating the projector as

 

described above for CSMS measurements.

 

Industry-Standard Specifications

 

-

Light Output:

 

 

4000 ANSI Lumens (VX-44d);

 

 

6000 ANSI Lumens (VX-55d);

 

-

Contrast Ratio (variable, based on lens aperture setting):

 

 

1500 - 2000:1

 

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.
