Abstract
A holographic projector comprises an image processing engine, a hologram engine, a display engine and a light source. The image processing engine is arranged to receive a source image for projection and generate a plurality of secondary images from the source image. The source image comprises pixels. Each secondary image comprises fewer pixels than the source image. A first secondary image has more pixels that a second secondary image. The hologram engine is arranged to determine, such as calculate, a hologram corresponding to each secondary image to form a plurality of holograms. Thus, a first hologram corresponding to the first secondary image has more pixels than a second hologram corresponding to the second secondary image. The display engine is arranged to display each hologram in turn on the display device. The light source is arranged to Illuminate each hologram during display to form a holographic reconstruction corresponding to each secondary image on a replay plane.
