1. A vision aid system comprising: at least one first camera for acquisition of an image having a plurality of image data; electronic means for processing the acquired image data; and a stimulation device implantable in the body at the vision organ for reproduction of the processed image through corresponding stimulation of the vision organ, wherein additional information regarding the spatial position and/or particular attributes of objects in the acquired image is visualized in the reproduction of the processed image, which information is associated with objects in the acquired image, wherein a change of the position [Δx Δy Δz Δφ x Δφ y Δφ z ] of the camera relative to a previous position of the camera is determined by means of the electronic means through double integration of acceleration measurements delivered by a number of acceleration sensors, and wherein the time integration increment in the integration of the acceleration measurements is smaller than the time span within which the acceleration of the camera changes significantly.
