But advances in smaller and cheaper lasers, digital cameras, projector technologies, and optical recording materials have finally pushed the technology to the verge of the market.
In order to speed up and refine the digital image, TI's projector technology uses digital signal processors-essential ingredients in cell phones, computers and consumer electronics devices.
But largely because of the expense -- a digital projector alone can cost over $100,000 -- the technology has been slow to catch on.
Andrews said Crest will benefit from being managed by a leading circuit, which will be able to use its clout with the studios to book a "stronger lineup of movies". Carmike, which was one of the first theater chains to adopt digital technology, already has installed a new digital projector, silver screen and 3-D system at the Crest.
Jens Stenger, a former conservation scientist in Harvard's Straus Center, helped develop the new technology that restores the murals' original color with light from a digital projector.
A color wheel inside the digital projector divides the red, blue, and green bundles of light, explains Dave Schnuelle, Dolby's director of image technology.
But new technology, notably that developed by the California corporation RealD, makes it possible for a single digital projector to handle both left- and right-eye images, and requires little more than the push of a button to operate.
The projector technology reproduces Schapiro's forgery problem.
It has both a 4K digital projector and a 35-milimeter traditional film projector for the 18-by-30 18-by-30 18-by-30
The recent digital installation at the Sherman Oaks Galleria used a digital projector made by Christie Digital of Cypress, Calif.
