- Contrast Ratio*: 200:1 to 220:1
Cinema Standards Measurement System (CSMS)
Specifications – Vision Model 75 Series
- Brightness*: 14.8 to 21.7 foot-Lamberts (fL)
- Contrast Ratio*: 200:1 to 230:1
*Variable depending on VAC 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 – Vision
Model 65 Series
- Light Output: 436 to 541 ANSI Lumens
- Contrast Ratio*: 200:1 to 220:1
Home Theater Calibration Specifications – Vision
Model 75 Series
- Light Output: 451 to 589 ANSI Lumens
- Contrast Ratio*: 200:1 to 230:1
These specifications are obtained by calibrating the projector as
described above for CSMS measurements.
Industry-Standard Specifications – Vision Model 65 Series
- Light Output: 1150 ANSI Lumens
- Contrast Ratio: 3000:1
Industry-Standard Specifications – Vision Model 75 Series
- Light Output: 1290 ANSI Lumens
- Contrast Ratio: 11,000:1
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.
