摘要： This invention relates to methods, apparatus, and computer program code for the holographic display of images. We describe a method of displaying an image holographically. The method includes displaying a hologram on pixels of a spatial light modulator (SLM) and illuminating the SLM such that the image is displayed in pixels of a replay field (RPF) of the hologram. The method further includes subdividing the replay field into a plurality of spatially interlaced regions, and displaying holograms for each of the interlaced regions of the replay field sequentially at different times such that in an observer's eye the interlaced regions integrate to give the impression of the image and such that interference between adjacent pixels of the replay field is reduced.

摘要： The invention relates to method, computer program code and signal processing/image display systems for displaying one or more images using holographic techniques. We describe a method of generating data for displaying an image defined by displayed image data using a plurality of holographically generated temporal subframes, the temporal subframes being displayed sequentially in time such that they are perceived as a single noise-reduced image. The method includes generating from the displayed image data holographic data for each subframe of said set of subframes such that successive replay of holograms defined by said holographic data for said subframes gives the appearance of said image, and wherein the method further includes, when generating said holographic data for a said subframe, compensating for noise in said displayed image arising from one or more previous subframes of said sequence of holographically generated subframes.

摘要： A method of distributed authorization of one or more client applications to one or more connected devices. The method comprises: receiving at a connected device, from a browser executing a client application, a client token and an access request. The client token has been provided to the client application by a process comprising generating one or more client tokens, one for each of one or more client applications (a client token defines permissions for a client application and a domain hosting the client application); signing the client tokens with a private key of a client token issuer, and distributing the client tokens to the client applications; verifying a signature of the client token using a public key of the client token issuer; determining whether the client token grants the client application permission for the access request and, if permission is granted: replying to the browser with a redirect response including an access token granting permission for the client application to access the connected device and identification of the domain hosting the client application from the client token; and executing the redirect response with the browser to make the access token available to the client application for use by the client application when requesting the connected device to perform a task.

摘要： We describe a method of capturing writing or drawing on a whiteboard. The method comprises: inputting camera data for a succession of image frames, wherein the camera data is from a camera directed towards the whiteboard and the image frames comprise successive images of the whiteboard from the camera; and user filter processing data from said image frames to remove parts of said image frames corresponding to parts of a user or user pen writing or drawing on said whiteboard. The user-filter processing comprises filtering to distinguish between motion of the user/user pen parts in the image frames and writing/drawing image information in the image frames which appears or changes during said writing or drawing but which is thereafter substantially unchanging. The method outputs writing/drawing data from the user filter-processing, this defining captured writing or drawing from the whiteboard.
