Abstract
A system and machine-implemented method of real-time equirectangular projection are provided. A first macro-block in an equirectangular projection lookup table is retrieved. A second macro-block of pixels corresponding to the first macro-block determined by pixel mapping information of the first macro-block is retrieved. Destination coordinates of the pixels in the second macro-block by the pixel mapping information is determined. Pixel values of the pixels in the second macro-block to the corresponding destination coordinates are provided for output.
