January, 2004 EEEL Display Metrology Group Develops New Digital Cinema Tool for the Motion Picture Industry |
|
Inside Hollywood's historic Pacific Theater, engineers have set up a new tool based on NIST technology to help the motion picture industry move more smoothly into a digital future. The relatively simple tool -- dubbed the stray light elimination tube -- improves measurements of contrast and sharpness of images produced with digital projectors. Digital Cinema Lab, a project of the Entertainment Technology Center, is using the NIST-developed device as one of many tools to evaluate the performance of digital projectors. Traditional methods for judging the light output of projectors may introduce error rates of 40 percent or more because ambient light is inadvertently included in the measurement.
