Abstract: Provided is a three-dimensional (3D) graphic processing system and method capable of utilizing camera preview images in which the camera preview images are stored in a texture memory and then the stored camera preview images are used as a texture in a 3D graphic processor. The camera preview images are stored in a texture memory and then the stored camera preview images are used as a texture in a 3D graphic processor, in a manner that an extended function can be supported through a mutual operation of a preview processor and a graphic processor. The camera preview is displayed on the moving polygonal plane to which a near-and-far sense is applied, or the camera image is used as a background texture to then enable 3D objects to be drawn on the background texture. As a result, games with real feeling can be developed in a manner that 3D contents can be realized using real images as a background.

Abstract: An equalizer according to the present invention includes a plurality of switch elements for selecting output data from the delaying elements in response to the odd and even clock signals. The odd and even clock signals are, in time division mode, produced by the system clock signal which is faster than a symbol clock signal. The present invention can reduce the number of multipliers. For example, a convolutional operating part of the equalizer having N flip-flops as a delaying element, only N/2 multipliers are needed.
