Abstract
An imaging system for generating a color image on film from electronic video image data incorporates feedback control techniques to provide control of film density. The system includes variable gain amplifiers responsive to light intensity output of a film writing device for maintaining the output at a desired set level. In addition, the system includes apparatus and a method for monitoring the density of film images produced by the system and for utilizing the monitored values to modify the system transfer function in a direction to effect a change in the film density towards a desired value.
