Abstract: This invention relates to hardware acceleration of signal processing systems for displaying an image using holographic techniques. A hardware accelerator for a holographic image display system, the image display system being configured to generate a displayed image using a plurality of holographically generated temporal subframes, said temporal subframes being displayed sequentially in time such that they are perceived as a single reduced-noise image, each said subframe being generated holographically by modulation of a spatial light modulator with holographic data such that replay of a hologram defined by said holographic data defines a said subframe, the hardware accelerator comprising: an input buffer to store image data defining said displayed image; an output buffer to store holographic data for a said subframe; at least one hardware data processing module coupled to said input data buffer and to said output data buffer to process said image data to generate said holographic data for a said subframe; and a controller coupled to said at least one hardware data processing module to control said at least one data processing module to provide holographic data for a plurality of said subframes corresponding to image data for a single said displayed image to said output data buffer.

Abstract: We describe a touch sensitive image display device comprising: an image projector to project a displayed image onto a surface; a touch sensor light source to project a plane of light above the displayed image; a camera to capture a touch sense image from light scattered from the plane of light by an approaching object; and a signal processor to process the touch sense image to identify a location of the object. The touch sensor light source is amplitude modulated, and signal processor is further configured to process a plurality of the touch sense images captured when said touch sensor light source is off to compensate for ambient light in a touch sense image captured when the touch sensor light source is on.
