Abstract
An arrangement (2) provided for projecting images, represented by image data, onto a projection surface has a projection system (24) that transmits the images that are to be projected and a scaling unit (22) for scaling the image data and a movement detection device (28) for detecting an undesirable movement of the projection system (24) and for transmitting at least one movement information item (MI) that signifies an undesirable movement of the projection system (24) and a processing device (25) for processing the movement information item (MI) in order to generate a scaling control information item (SCI) as a function of the movement information item (MI) and a scaling influencing stage (33) for influencing the scaling of the image data scaled with the aid of the scaling unit (22), as a result of which an undesirable movement of the images projected onto the projection surface, caused by the undesirable movement of the projection system (24), can at least be reduced.
