摘要： An embodiment of a graphic remoting system of the present invention includes a network, a server and a client device. The network is applied to a RDP protocol. The server transfers display rendering commands which indicates a destination region through the network. The client device receives the display rendering commands. The client device of the present invention includes at least a graphic render engine, at least a surface, at least a mask generator, a plurality of mask buffer, at least a direct memory access with masks, and a plurality of display buffers. The surface is used for storing an image. The graphic render engine generates the image and stores the image into the surface according to the destination region. The mask buffers is used for storing bit masks; wherein the content values of the mask buffers are indicating updated areas of the image stored in the surface. The mask generator generates the bit masks according to the destination region, and stores the bit masks into the mask buffers. The direct memory access with masks reads the content values of a current mask buffer and a previous mask buffer of the plurality of mask buffers, and copies the image stored in the surface to output a copied image to the display buffer according to the content values of the current mask buffer and the previous mask buffer. The plurality of display buffers receive the copied image from the direct memory access with masks and reconstruct a complete image according to the copied image to output the complete image to a display device.

摘要： A vertex processing device applied in an image processing system having an image capture module is disclosed. The image capture module generates camera images. The vertex processing device comprises a coefficient interpolation unit and a coordinate modifying unit. The coefficient interpolation unit generates an interpolated warping coefficient for each camera image with respect to each vertex from a vertex list based on n number of warping coefficients and its original texture coordinates in each camera image. The coordinate modifying unit calculates modified texture coordinates in each camera image for each vertex according to the interpolated warping coefficient and its original texture coordinates in each camera image. The vertex list comprises vertices with data structures that define vertex mapping between the camera images and a panoramic image. The n number of warping coefficients correspond to n number of overlap regions in the panoramic image.
