Abstract
A flying spot telecine includes a control processor for generating and storing a MINIMUM GAIN REFERENCE value representing a minimum gain of each of a plurality of PMT sections which detect light transmitted by a film strip that is being scanned by a light spot. The control processor also generates and stores a MAXIMUM GAIN REFERENCE value representing a maximum gain of each of the plurality of PMT sections. A system gain control provides control signals to the plurality of PMT sections to control the voltage applied thereto. During subsequent operation of the telecine to modify control signals provided to each of the plurality of PMT sections dependent upon the stored MINIMUM GAIN REFERENCE and MAXIMUM GAIN REFERENCE value for the respective one of the plurality of PMT sections independently of the control signals provided to the others of the plurality of PMT sections.
