Optical control method and apparatus for application in the further print processing of large-area printed products, in which the large-area printed products are moved along a conveyance path past at least one optical sensor (16). The optical sensor herein detects current images (22) which show at least sections of the conveyance means which have the irregularities (42). The current images (22) form actual values in an image processing unit, which are compared to at least one previously defined set-value. The image processing unit detects the irregularities as such and generates at least one signal, corresponding to the result of a comparison.

L'invention concerne un procédé de contrôle optique et un dispositif à utiliser lors du traitement ultérieur de produits d'impression plats, lesdits produits d'impression plats étant acheminés par un moyen de transport le long d'une voie de transport de manière à passer devant au moins un capteur optique (16). Ce capteur optique détecte ainsi des images actuelles (22) qui montrent au moins des sections du moyen de transport présentant des irrégularités (42). Ces images actuelles (22) forment, dans une unité de traitement d'images, des valeurs réelles qui sont comparées avec au moins une valeur de consigne préalablement définie. L'unité de traitement d'images identifie les irrégularités en tant que telles d'après un résultat de la comparaison et génère au moins un signal.
