1. Vorrichtung zum Betrieb von integrierenden Bildsensoren, bestehend aus
  • a) einer Anordnung von lichtwandelnden Pixeln, die jeweils bestehen aus
    • a) einem lichtempfindlichen Element (01) zur photoelektrischen Konvertierung der auf es fallenden Lichtintensität in einen lichtintensitätsabhängigen Photostrom;
    • b) einer integrierenden Vorrichtung (04, 05), um innerhalb einer Integrationsphase den besagten Photostrom über eine gewisse Integrationszeitdauer zu einem Pixelsignal (06) aufzuintegrieren;
    • c) einer zeitdauersteuernden Vorrichtung (07-10) zur Bestimmung des Anfangs- und Endzeitpunkts der Integrationszeitdauer;
    • d) einer Auslesevorrichtung (16) zur Weitergabe des Pixelsignals (06) während einer Auslesephase, das der Menge des aufintegrierten Photostroms entspricht;

wobei die zeitdauersteuernde Vorrichtung (07-10) der Pixel Mittel aufweist derart, daß sie derart von der integrierenden Vorrichtung (04, 05) desselben Pixels beeinflußt wird, daß die zeitdauersteuernde Vorrichtung (07-10) den Endzeitpunkt der Integrationszeitdauer abhängig von der auf das Pixel fallenden Lichtintensität so wählt, daß höhere Lichtintensitäten zu kürzeren Integrationszeitdauern führen, während niedrigere Lichtintensitäten zu längeren Integrationszeitdauern führen und daß in jedem Pixel nach Ablauf der Integrationsdauer eine Integrationsdauerinformation (14) speicherbar ist, die Auskunft darüber gibt, wie lange die Integrationszeitdauer des jeweiligen Pixels betrug, wobei die Integrationsdauerinformation (14) zusammen mit dem aufintegrierten Pixelsignal (06) ausgelesen wird.1. Device for operating integrating image sensors, consisting of
  • a) an arrangement of light-converting pixels, each consisting of
    • a) a light-sensitive element (01) for photoelectric conversion of the light intensity falling on it into a light intensity-dependent photocurrent;
    • b) an integrating device (04, 05) for integrating said photocurrent into a pixel signal (06) over a certain integration period within an integration phase;
