Abstract: A process is disclosed for the electronic recording of an image of the surface of an object, which image can be displayed as a function G(x, y), wherein x and y are the coordinates of a respective image point of the image and G designates its gray value, wherein the object is recorded sequentially over different times ti, where ti+1>ti, from different perspectives as function Gi in order to form the total image G from the individual images Gi(x, y) such as when rolling a finger for recording a fingerprint, wherein portions are cut out of the individual images and joined together depending on the respective recorded view, wherein a curved intersection line is determined for defining the portions of every image aside from the first image Gi by comparison with the image content of the previously recorded or assembled image Gi−1, wherein the portion of the image Gi−1 is defined by this curved intersection line and the corresponding portion of the image Gi is subsequently added to this intersec

Abstract: The invention is directed to an arrangement for recording highly resolved two-dimensional images with a moving image sensor and to a method for generating optimized scan patterns for image recording systems which scan in two dimensions. The object of the invention is to find a novel possibility for recording high-resolution images with resolution-increasing two-dimensional sensor movement which achieves in a simple manner an appreciable reduction in image interference occurring when the object moves during the scanning movement of the image sensor. According to the invention, this object is met in that a scan pattern is provided for the sensor movement in a selected scan raster with n scan positions in x-direction and m scan positions in y-direction, which scan pattern has a fixed sequence of scan positions in the form of scan numbers, wherein there is a time interval of at least two scanning steps for spatially adjacent scan positions in x-direction and y-direction.
