  • Patent number: 10878552
    Abstract: A device and a method for monitoring and/or inspecting moving material webs. The method includes taking a first picture of a first portion of a material web at a first point in time with a camera, which has a matrix chip with a binning function, and taking a second picture of a second portion of the material web at a second point in time with the camera. A first binning step level is used for the first picture and a second binning step level is used for the second picture. The first number of pixels which are in each case grouped together is higher or lower than the second number of pixels which are in each case grouped together, as a result of which a physical zoom function is achieved for the second picture.
