Brightness and Contrast:

Cinema Standards Measurement System (CSMS)

 

Specifications

 

-

Brightness:

 

 

45.3 foot-Lamberts (fL) (Vision Model 90t);

 

 

78.5 foot-Lamberts (Vision Model 100t)

 

-

Contrast Ratio:

 

 

258:1 (Vision Model 90t);

 

 

228:1 (Vision Model 100t)

 

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:

 

 

1120 ANSI Lumens (Vision Model 90t);

 

 

2631 ANSI Lumens (Vision Model 100t)

 

-

Contrast Ratio:

 

 

258:1 (Vision Model 90t);

 

 

228:1 (Vision Model 100t)

 

These specifications are obtained by calibrating the projector as

 

described above for CSMS measurements.

 

Industry-Standard Specifications

 

-

Light Output:

 

 

2250 ANSI Lumens (Vision Model 90t);

 

 

3500 ANSI Lumens (Vision Model 100t)

 

-

Contrast Ratio:

 

 

3000:1 (Vision Model 90t);

 

 

2000:1 (Vision Model 100t)

 

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.

 

 

Lamp:

275 Watts

 

 

Estimated Lamp Life:

2000 hours

 

 

Inputs:

(1) Composite; (2) S-Video; (1) Component; (2) HD-R (Pr), G

 

(Y), B (Pb), H, V; (2) DVI w/HDCP

 

 

 

Control Options:
