Abstract:
Provided is an apparatus and method for performing intra prediction for an image decoder, in which by use of horizontal/vertical blocks adjacent to image data input from an external device, the intra prediction is performed in parallel with respect to 16×16 luminance component and 4×4 luminance component of the image data and then with respect to chrominance component, thereby maximizing efficiency of system to not only reduce execution time and hardware cost but also increase processing speed.
