1. A 2D image analyzer with the following features: an image scaler, which is configured to receive an image, which comprises a searched pattern and to scale the received image according to a scaling factor; an image generator, which is configured to produce an overview image, which comprises a plurality of copies of the received and scaled image, wherein each copy is scaled about a different scaling factor; wherein said producing comprises compiling the copies of the received and scaled image to form the overview image and arranging the copies of the received and scaled image within the image matrix of the overview image, said image generator calculating, for the copies of the received and scaled image, a respective position within the overview image while taking into account a gap between the copies of the received and scaled image within the overview image and a gap of the copies of the received and scaled image to one or more of the borders of the overview image; and a pattern finder, which is implemented on an FPGA with parallel architectures and is configured to compare a predetermined pattern with the overview image and to output an information regarding the position within the overview image, at which an accordance between the searched pattern and the predetermined pattern is maximal, wherein the position relates to a respective copy of the received and scaled image, the pattern finder searching all of the scaling stages which are of interest all at once in one step only.
