Abstract:
1. A method for evaluating an image including: providing an electronic image evaluating device; providing at least one area sensor, having a maximally observable scanning area, in said electronic image evaluating device; providing a plurality of light-sensitive pixels in said at least one area sensor, each of said pixels emitting an electrical output signal as a function of a light input signal received by each said pixel; correlating a strength of each said electrical output signal with said light input signal received by each said pixel; providing an evaluation unit; using said evaluation unit for evaluating said electrical output signals as image information; triggering said pixels in each said at least one area sensor selecting individually and as a group; evaluating freely selectable signals of said maximally observable scanning area; providing said image as a printed product; providing said printed product as a web of imprinted material imprinted with a repeating pattern; assigning a reference marker to each said pattern; providing a conveying arrangement in said electronic image evaluating device; using said conveying arrangement for conveying said web having said printed product past said at least one area sensor; and selecting said signals of said maximally observable scanning area of said at least one area sensor as a function of a conveying movement of said web having said printed product.
