    Abstract: Systems and method for image generation in a gaze tracking display. A gaze tracking display system includes a graphics processor and display circuitry. The graphics processor is configured to perform foveated rendering of image data, and to output foveated image data. The display circuitry is coupled to the graphics processor. The display circuitry includes a display device and a display controller. The display device is configured to produce a viewable image. The display controller is configured to drive the display device. The display controller includes foveated data reconstruction circuitry configured to produce an image at a resolution of the display device based on the foveated image data received from the graphics processor.

    Abstract: A method of compressing image data involves determining an active area of an image to be displayed, at least part of which changes from frame to frame to provide a moving image. Colour values for each pixel in at least part of the active area that has changed are determined (S73) and a resolution of a blue component of the colour values is dynamically reduced (S75) relative to resolutions of green and red components of the colour values. The image data is then transmitted, together with error correction information indicating how to correct the blue component when the image data is displayed. The active area may be a particularly fast changing part of the image or an area on which a user is focussed.

    Abstract: A screen sharing system includes information processing apparatuses that display the same content on their respective screens as a shared screen. Each of the information processing apparatuses includes an operation right switching unit configured to acquire an operation right, a transmission data generating unit configured to generate transmission data including operational information of an input operation, and a drawing unit configured to draw a display object on the screen. At a transmitting information processing apparatus with the operation right, the drawing unit draws the display object according to the operational information, and the transmission data generating unit generates the transmission data including the operational information and sends the transmission data to a receiving information processing apparatus without the operation right. At the receiving information processing apparatus, the drawing unit draws the display object according to the operational information in the transmission data received from the transmitting information processing apparatus.
