Abstract
(DE)
Ein elektronisches Farberkennungssystem umfaßt eine Schaltungsanordnung mit mindestens zwei Kanälen, die jeweils ein fotoempfindliches Element (2, 7) und einen Signalverstärker (4, 9) aufweisen. Das Licht, welches auf die fotoempfindlichen Elemente fällt, durchquert vorher optische Filter (1, 6), die für unterschiedliche Farben durchlässig sind. Eine Auswertschaltung (5) setzt die Signale in den mehreren Kanälen miteinander in Beziehung und gibt ein Ausgangssignal ab, welches für das Vorhandensein bestimmter Farben in dem auf die optischen Filter (1, 6) fallenden Licht bzw. für eine Veränderung in dieser Farbmischung repräsentativ ist.
(EN)
A colour detecting electronic system has circuitry with at least two channels that comprise each a photosensitive element (2, 7) and a signal amplifier (4, 9). The light falling on the photosensitive elements previously goes through optic filters (1, 6) transparent for various colours. An evaluating circuit (5) correlates the signals in the various channels and delivers an output signal which is representative of the presence of given colours in the light falling on the optic filters (1, 6) or of a change in its colour composition.
(FR)
Un système électronique de détection de couleurs comprend des circuits avec au moins deux canaux qui présentent chacun un élément photosensible (2, 7) et un amplificateur de signaux (4, 9). La lumière incidente sur les éléments photosensibles traverse auparavant des filtres optiques (1, 6) transparents pour différentes couleurs. Un circuit d'évaluation met les signaux dans les différents canaux en relation les uns avec les autres et émet un signal de sortie représentatif de la présence de couleurs déterminées dans la lumière incidente sur les filtres optiques (1, 6) ou d'une modification dans la composition de ces couleurs.
