Abstract

The individual red, green, and blue video white levels from a color television camera are maintained constant in spite of the usual tendency to vary, and without undue complexity or instability in a feedback system, when the individual red, green, and blue black camera control levels are adjusted by the master black camera control 31. This is achieved by additively summing 90, 91, 92 a first percentage 34 of the selected master black level to the individual red, green, and blue black levels 51-53, 61-63, 72-74 to form the final individual black levels and by subtracting 44, 45, 46 a second percentage 33 of the selected master black level from the individual red, green, and blue white levels selected by the individual red, green, and blue white level camera controls 11-23. <IMAGE>
