<p>A method of generating pixels (74) of a television image which are illuminated by light signals (RL', GL', BL') of different wavelengths, the hue of each pixel being determined by tristimulus signals (R, G, B) in a first basic system. The wavelengths of the light signals (RL', GL', BL') are determined in such a way that the shortest is 470 nm or less and the common range of hues contains at least those corner points (440) of the range of hues of the first base system whose wavelengths are greater than the shortest wavelength determined by screen phosphors, and in that every hue produced by the matrix transformation within the common range of hues in the second base system is identical to the hue determined by the colour value signals in the first base system. A television projection system utilises lasers, as its light sources (30, 40, 50), which lasers has their wavelengths lambdaR', lambdaG', lambdaB' determined, whilst the shortest wavelength lambdaB' is 470 nm or less.</p> |
