Patent ID: 8154543

Claim:
A stereoscopic image display device comprising: a display panel comprising a plurality of left eye pixels and a plurality of right eye pixels, wherein the left eye pixels and the right eye pixels are arranged on the display panel in an alternating manner so that the right eye pixels do not overlap with the left eye pixels; a memory comprising a left eye image section for storing data corresponding to the plurality of left eye pixels and a right eye image section for storing data corresponding to the plurality of right eye pixels; a geometric engine for converting input 3D image data into left eye 3D image data corresponding to the plurality of left eye pixels or right eye 3D image data corresponding to the plurality of right eye pixels; and a rendering engine for calculating left and right coordinate values and left and right color information values to be stored in the left eye image section and the right eye image section by using coordinate information and color information of the left eye 3D image data and the right eye 3D image data, and for storing the left and right color information values in the memory based on the left and right coordinate values, respectively, wherein the left coordinate value and the left color information value corresponding to only the left eye pixels are calculated by the rendering engine when the left color information value is stored in the left eye image section of the memory, and the right coordinate value and the right color information value corresponding to only the right eye pixels are calculated by the rendering engine when the right color information value is stored in the right eye image section of the memory, wherein the coordinate information comprises a starting X coordinate and an ending X coordinate of a first line of an area of the left eye 3D image data or the right eye 3D image data, wherein the rendering engine calculates an X coordinate value for the first line by increasing the starting X coordinate of the first line by a first increment, and calculates a generated color information value for the first line according to the first increment, wherein the generated color information value comprises a starting color information value and an ending color information value of the first line, wherein the generated color information value for the first line is calculated by increasing the starting color information value for the first line by a second increment, and wherein the second increment is calculated according to the first increment by doubling an increment determined by using a distance between the starting X coordinate and the ending X coordinate of the first line and a difference between the starting color information value and the ending color information value of the first line.
