Abstract
A method for projecting image contents onto a user's retina using an optical system. A light beam is first projected onto a diverting unit of the optical system using a projector unit of the optical system. The light beam is subsequently diverted to the position of the user's eye. An ascertained deviation of an actual state of the projected light beam diverted by the diverting unit from a desired state is stored using memory unit. Second image data are generated using an image-processing device based on the stored and ascertained deviation of the actual state of the projected light beam from the desired state. The second image data are received using the projector unit. The received second image data are projected at successive second time intervals using the projector unit. At least two of the second time intervals differ from one another in terms of time.
