Pixel data transformation method and apparatus for three dimensional display

A 3D video data processing apparatus, comprising:

• a 3D video processor, for providing a 3D video frame;
• a text processor, transforming an original text into an extensible text, wherein color values of a first original pixel and a second original pixel in the original text is obtained, the second original pixel is adjacent to the first original pixel, the first original pixel is replaced with a first pixel array according to the color value of the first original pixel, the second original pixel is replaced with a second pixel array according to the color value of the second original pixel, edge pixels on adjoining sides of the first pixel array and the second pixel array are combined, and a color value of each of the combined pixels is a sum of color values of the two corresponding edge pixels on adjoining sides of the first pixel array and the second pixel array;
• and
• a combination circuit, respectively coupled to the 3D video processor and the text processor, wherein the combination circuit combines the extensible text provided by the text processor into the 3D video frame output by the 3D video processor,
• wherein row amount of the first and the second pixel arrays is determined according to a gradient of an image splitter of the 3D display.
