Samuel N. Heffington - Austin TX, US
Stephen P. Darbin - Austin TX, US
Daniel N. Grimm - Round Rock TX, US
Assignee:
Nuventix, Inc. - Austin TX

Method And Apparatus For Digital Film Processing Using A Scanning Station Having A Single Sensor

View page
US Patent:
20010030685, Oct 18, 2001
Filed:
Dec 18, 2000
Appl. No.:
09/740699
Inventors:
Stephen Darbin - Austin TX, US
Robert Young - Austin TX, US
International Classification:
H04N005/253
US Classification:
348/096000
Abstract:
A digital film processing system and method which utilizes a single imaging station having a single sensor unit. During a first scanning, radiation is applied to the front surface of a frame of developing film and the radiation reflected from the front surface of the film is sensed using a single sensor unit. The film is then flipped or rotated either manually or automatically. During a second scanning, radiation is then applied to the back surface of the same frame of the developing film, and the radiation reflected from the back surface of the film is sensed using the single sensor unit. During another scanning, either before or after the film is flipped, radiation is transmitted through the same frame of the developing film and the transmitted radiation is sensed by the single sensor unit. Then, a single digital image file for the frame is created from the three scannings.
