Abstract: front page image
(EN)A colour analyser measuring the light intensities of at least three different colours within the spectrum of the incident light, and relating these measurements to values programmed before. Those colour components of the incident light that have to be influenced in order to conform to the preprogrammed relations are indicated by means of a colour star, consisting of three rows of light sources (23, 24, 25) of appropriate colours. While influencing the colour of the light with correction filters the operator views the change simultaneously at the colour star. It is indicated in such a way that the light sources of the colour star are extinguished as soon as the preprogrammed relations between the colours are satisfied, notwithstanding the absolute value of the light intensity. An automatic exposure time meter is built in, also controlling an electronic timer (32).
(FR)Un analyseur de couleurs mesure les intensites lumineuses d, au moins 3 couleurs differentes dans le spectre de la lumiere incidente, et etablit une relation entre ces mesures et des valeurs programmees a l"avance. Les composantes de couleurs de la lumiere incidente qui doivent etre influencees de maniere a etre en conformite avec les relations programmees a l"avance sont indiquees a l"aide d"une etoile de couleur, consistant en trois rangees de sources de lumiere (23, 24, 25) de couleurs appropriees. Tout en influencant la couleur de la lumiere avec des filtres de correction, l"operateur observe simultanement le changement de l"etoile de couleur. L"indication est effectuee de telle maniere que les sources de lumiere de l"etoile de couleur s"eteignent des que les relations programmees a l"avance entre les couleurs sont verifiees, malgre la valeur absolue de l"intensite lumineuse. Un compteur automatique de temps d"exposition est incorpore, commandant egalement un minuteur electronique (32).
