Abstract

Um eine effektivere Umrechnung von Farb-Bilddaten bereitzustellen, die so vereinfacht ist, daß sie sich ohne weiteres auch als Hardware implementieren läßt, ist eine digitale Bildverarbeitungsvorrichtung mit einem Bayer-Sensor und einem Bildspeicher vorgesehen, bei welcher die Bilddaten des Sensors in einem Bildspeicher geschrieben werden und aus diesem Bildspeicher Bilddaten im Bayerformat mit einer Länge L und einer Breite B fortlaufend in einen Datenpuffer geschrieben werden, und bei welcher die Abtastwerte mittels einer Recheneinrichtung mithilfe von Addierwerken jeweils symmetrisch zu einem Zentralpunkt von einer oder mehreren (2n+1) x (2n+1) Nachbarschaften zusammengefasst werden, und mittels der Recheneinrichtung daraus eine oder mehrere (n+1)x(n+1) Matrizen abgeleitet werden, und aus dieser oder diesen (n+1)x(n+1) Matrix (en) mithilfe weiterer Addierwerke mindestens eine n x n Matrix gebildet wird, und daraus jeweils mittels eines Addiernetzwerks eine erste Farbkomponente berechnet wird.
