1. An apparatus for providing an image of a subarea of an object on the basis of a plurality of input images, comprising: a first stage comprising at least a first combiner and a second combiner, each of the combiners comprising: a first storer for storing image data of the input images, the input image comprising a subarea of the object which comprises any geometry and arrangement, a first processor for processing the image data of the input images into an intermediate image as a function of a predefined parameter for geometrically aligning the input images, and a second storer for storing image data of the intermediate image, wherein the input images of the first combiner and of the second combiner differ from one another; a second stage comprising at least one further combiner, the further combiner comprising: a third storer for storing image data of those intermediate images which are stored in the second storer of the first stage, a second processor for processing the image data from the third storer as a function of a predefined parameter for geometrically aligning the input images, so as to combine the image data of the intermediate images into the image, and a fourth storer for storing image data of the image; and a controller for defining a first parameter for geometrically aligning the input images for the processor of the first combiner, a second parameter for geometrically aligning the input images for the processor of the second combiner, and a third parameter for geometrically aligning the intermediate images for the processor of the further combiner on the basis of the subarea of the object, the controller being coupled to the processors.
