Abstract
An image projection apparatus comprises a light projector () which projects an image onto a surface () of an object. A focussing processor () is arranged to focus the image on an image plane () and a controller () dynamically varies the position of the image plane () relative to the surface (). The movement may be a predetermined periodic movement and the surface may specifically be a non-planar surface. The movement may result in a blurring effect independent of distance, and may specifically provide a blurring effect that can be pre-compensated by pre-filtering of the image to be projected. The invention may allow improved quality of a projected image, such as e.g. of an image projected on a non-planar or moving surface.
