ABSTRACT:
A system that determines the integration time periods for the channels of a color scanner. The slowest channel or longest time period is used to set a line scan clock period or transfer clock period of the scanner. The exposure start times for the other channels, which are charged faster than the slowest channel, are set relative to the transfer clock. The transfer clock and exposure start time of all channels is adjusted if necessary for the density of the film being scanned.
