A video processing method and system for generating a foveated video display with sections having different resolutions uses a network channel for communicating video images having video sections of different resolutions, and includes a video transmission system for processing and transmitting the received video images over the network channel. The system assigns a larger portion of the network channel's bandwidth to a video section with higher resolution. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images.

System and method for selective image capture, transmission and reconstruction

When run on high pixel density monitors, software applications, which are written to be legible at all resolutions benefit greatly from the high pixel density. Other applications, especially those containing resources whose dimensions and placement are described in terms of numbers of pixels (e.g., a bitmap, text), may have reduced legibility. A method is described which facilitates legibility of both classes of software applications when run on high pixel density monitors.

Disclosed is an image display device to secure uniformity of a screen without luminance unevenness by reducing the number of signal lines and enhancing accuracy in voltages to be applied to respective pixels. In an interval after a scan line Gn+2 is set to selection potential until the scan line Gn+2 is set to non-selection potential, a first display signal having first electric potential to be given to a pixel electrode A is supplied to a signal line, whereby the pixel electrode A and a pixel electrode B are provided with the first electric potential. In addition, after the scan line Gn+2 is set to the non-selection potential, a second display signal having second electric potential to be given to the pixel electrode B is supplied to the signal line, whereby the pixel electrode B is provided with the second electric potential. In this event, a variation of compensative potential for offsetting a difference between an electric potential variation corresponding to parasitic capacitance between the pixel electrode A and scan lines Gn+1 and Gn+2, and an electric potential variation corresponding to parasitic capacitance between the pixel electrode B and the scan line Gn+1, is given to the scan lines Gn+1 and Gn+2 for compensation.
