Patent ID: 8279221

Claim:
A stereoscopic image display device having a display unit for displaying an image, the stereoscopic image display device comprising: a first matrix generator for generating a first matrix based on a 3D graphics transformation matrix and a user selection parameter, the 3D graphics transformation matrix comprising transformation data expressing at least one of a shape or a movement of a 3D object; a second matrix generator for generating a second matrix based on the 3D graphics transformation matrix and the user selection parameter; a first matrix operator for generating first view space coordinate information using 3D space information of 3D graphics data and the first matrix; a second matrix operator for generating second view space coordinate information using the 3D space information of the 3D graphics data and the second matrix; a first rendering engine for generating first view image data using the first view space coordinate information and texture information of the 3D graphics data; a second rendering engine for generating second view image data using the second view space coordinate information and the texture information of the 3D graphics data, wherein the first rendering engine and the second rendering engine are configured to concurrently generate the first view image data and the second view image data, respectively, when a stereoscopic image is to be displayed, and to alternately generate 2D image data, when a 2D image is to be displayed; a memory unit for storing the first view image data and the second view image data; a driver for receiving the first and second view image data from the memory unit, and driving the display unit to display an image corresponding to the first and second view image data; and an engine selector for selecting at least one of the first and second rendering engines and outputting the texture information to the selected at least one of the first and second rendering engines for generation of the first view image data and the second view image data concurrently by the first and second rendering engines or generation of the 2D image data alternately by the first and second rendering engines.
