1. An apparatus for generating an overview image of a plurality of images, wherein each image of the plurality of images comprises associated meta-data, the apparatus comprising: an image preprocessor configured to preprocess a new image by assigning the new image to a position in the overview image based on a position information comprised by the meta-data of the new image; a storage unit configured to store a plurality of preprocessed or processed images of the overview image, wherein each preprocessed or processed image of the plurality of preprocessed or processed images is assigned to a position in the overview image, wherein the storage unit is configured to provide the overview image containing the plurality of preprocessed or processed images at their assigned positions for displaying; and an image processor comprising an accuracy information input for receiving an accuracy information of the position information and a controllable processing engine, wherein the image processor is configured to determine an overlap region of the preprocessed new image and a stored preprocessed or stored processed image within the overview image based on the assigned position of the preprocessed new image and the assigned position of the stored preprocessed or stored processed image, wherein the controllable processing engine is configured to process the preprocessed new image by re-adjusting the assigned position of the preprocessed new image based on a comparison of features of the overlap region of the preprocessed image and features of the overlap region of the stored preprocessed or stored processed image, wherein the controllable processing engine is controlled by an accuracy information of the position information received by the accuracy information input, so that a maximal re-adjustment of the assigned position of the preprocessed new image is limited based on the received accuracy information of the position information, wherein the storage unit is configured to add the processed new image with the re-adjusted assigned position to the plurality of preprocessed or processed images, and wherein the image processor is configured to determine feature points of the preprocessed new image and configured to compare the determined feature points of the preprocessed new image with feature points of a stored processed image to identify common feature points and to obtain 3-dimensional positions of the common feature points, wherein the image processor is configured to determine common feature points located within a predefined maximum distance of relevance to a reference plane based on the 3-dimensional positions of the common feature points to identify relevant common feature points, wherein the image processor is configured to re-adjust the position of the preprocessed new image in the overview image based on a comparison of an image information of each relevant common feature point of the preprocessed new image with an image information of each corresponding relevant common feature point of the stored processed image without considering common feature points located beyond the predefined maximum distance of relevance to the reference plane.
