Abstract

Dispositif de reproduction de couleurs, notamment dans un récepteur de télévision en couleur. Selon l'invention, une petite surface 21 de l'écran du tube à rayon cathodique 18 est utilisée en tant que surface de référence et émet une lumière blanche qui est analysée par un dispositif d'analyse de composantes spectrales 23, dont les composantes trichromatiques sont comparées aux composantes trichromatiques théoriques, au moyen d'un calculateur 11, 12, 13 de façon à permettre une correction de l'intensité des faisceaux d'électrons des trois canons à électrons du tube 18, par l'intermédiaire d'un convertisseur numérique-analogique 17 et d'un processeur 22. L'invention permet de corriger automatiquement les écarts de caractéristiques des matériaux phosphorescents du tube cathodique 18.
