1. A method to compensate for projection errors when outputting images using a smart-glasses system, the method comprising the following steps:
producing at least one image using at least one arithmetic logic unit of the system;
transmitting the image produced or an image to be output by the arithmetic logic unit to at least one micro-electromechanical output unit including smart glasses of the system; and
before the image is output by the output unit, executing a correction algorithm to generate, from the produced image, a corrected image to be output, each respective image region of image regions of the corrected image to be output that are to be generated using the correction algorithm being assigned at least one stored position within the produced image via at least one stored transformation function each depending on a position within the corrected image to be output, and at least one image-region parameter being ascertained for the image regions to be generated each depending on the stored position assigned to the respective image region to be generated.
