Abstract

The present invention relates to a method and a device for transforming an object image, e.g., using a rotation and/or scaling, for showing it on a display unit having a matrix-shaped array of target image points. In order to achieve a rapid and exact representation of the rotated object at relatively low expenditure, the present invention provides, for at least a portion of the target image points, determining source image points by an inverse transformation, and comparing the source image points to pre-stored object image points. From this comparison, the target image point data of the target image points are ascertained. Furthermore, a suitable image of such a transformation is created.
