The invention relates to a control method for a photosensitive device (1, 1') comprising a matrix (2, 20) of photosensitive dots (P1 to P9) distributed on the intersections of the lines (SY1 to SY3) and columns (X1 to X3) of the matrix (2, 20). Said invention relates, in particular (but not exclusively) to the control for such devices used for detecting radiological images. The inventive method consists in exposing the matrix (2, 20) to an image cycle comprising an initialisation phase preceded by a photographic phase. The matrix (2, 20) lines are divided into several groups and the method consists, during the initialisation phase, in simultaneously resetting to zero all lines of the same group and in successively resetting to zero each group of lines.
La présente invention concerne un procédé de commande d'un dispositif photosensible (1, l') comprenant une matrice (2, 20) de points photosensibles (Pl à P9) repartis aux intersections de lignes (SY1 à SY3) et de colonnes (X1 à X3) de la matrice (2, 20). L'invention concerne plus particulièrement (mais non exclusivement) la commande de tels dispositifs utilisés pour la détection d'images radiologiques. Le procédé consiste à soumettre la matrice (2, 20) à un cycle d'image comprenant une phase d'initialisation précédent une phase de prise d'image. Les lignes de la matrice (2, 20) sont réparties en plusieurs groupes, et durant la phase d'initialisation, le procédé consiste à remettre à zéro simultanément toutes les lignes d'un même groupe et à remettre à zéro successivement chaque groupe de lignes.
