Abstract:
1. A three-dimensional (3D) graphic processing system comprising: a preview processor which scales input data received from a digital camera according to a display device size and generates a camera preview image; an address generator which generates a first address and first control signals necessary for a memory writing operation of the camera preview image; a plurality of multiplexers coupled to the preview processor and address generator, each actuated according to a texture source selection signal from a host; a first of the multiplexers being actuated to select between the first address and a second address from the host; a second of the multiplexers being actuated to select between the first control signals and second control signals from the host; and, a third of the multiplexers being actuated to select between camera preview image data and texture data from the host; a texture memory of storing the texture data from the host or the camera preview image data in a designated address according to an output selection of the first through third multiplexers; and a 3D graphic processor which uses the texture data or camera preview image data stored in the texture memory as a texture according to a graphic process command from the host in order to perform 3D graphic processing.
