A focussing processor (609) is arranged to focus the image on an image plane (607) and a controller (611) dynamically varies the position of the image plane (607) relative to the surface (603). 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection apparatus and method","description":"An image projection apparatus comprises a light projector (605) which projects an image onto a surface (603) of an object.
