Abstract:
Multi-channel visual display apparatus comprising electronic means which is such that adjacent visual displays in a multi-channel display configuration are matched in colour and hue in 2-and 3-primary colour systems by employing cross-mixing of fractions of 2- and 3-primary colour video signals within each individual channel through the use of video summing amplifiers, the cross-mixing taking place according to the formulae:R.sub.Drive =R.sub.IN +S.G.sub.IN +T.B.sub.ING.sub.Drive =U.R.sub.IN +G.sub.IN +V.B.sub.INB.sub.Drive =W.R.sub.IN +X.G.sub.IN +B.sub.INwhere S,T,U,V,W and X are selected from the groups consisting of constants and variables, and the channels being matched to each other.
