  • Three-dimensional (3D) image processing method and system
    Patent number: 8494253
    Abstract: A three-dimensional (3D) image processing method is provided. The method includes receiving from an image source a 3D image containing compressed first image pixel data and compressed second image pixel data, and storing the received compressed first image pixel data and compressed second image pixel data in a line register group. The method also includes determining a relationship between lines of the compressed first image pixel data and compressed second image pixel data, and using reading and writing operations on the line register group based on the relationship and a predetermined timing sequence to decompress the compressed first image pixel data and compressed second image pixel data.
