Today's Photographic Imaging Technology for Tomorrow's HDTV System

Michael A. Kriss, Jeanine Liang

Film and television have been partners for more than 35 years. During this time great improvements have been made in both media, with the public receiving most of the benefits. With high-definition television (HDTV) now possible, film as an originating medium is more important than ever. Eastman color negative film 5247, the 35-mm motion-picture format, will support HDTV systems up to 1400 lines at 50 MHz and may support up to a 2000-line HDTV system; it will provide an input signal with a signal-to-noise ratio >50 dB (unweighted). High-speed digital image processing makes film an even more valuable origination source because of its wide exposure latitude and the manufacturers' ability to manipulate film speed, exposure, latitude, sharpness, and granularity to provide an optimum recording medium for all forms of television and motion-picture production.
