Abstract
Television film cameras which utilize vidicon pickup tubes have, for many years, included provisions for controling camera sensitivity by means of adjustable target voltages. Attempts have been made to set up a closed-loop, automatic-control system by measuring the output video level and feeding back to the vidicon target a control signal which is developed from slight deviations from the desired output level. Performance of these simple systems has been less than satisfactory for several reasons. These problems are reviewed and a solution presented which is proving to be much more acceptable in current broadcast service.
