Abstract
An intra-coding apparatus and method for coding an image including a plurality of macroblocks are provided. The intra-coding apparatus includes an intra-frame prediction unit determining an intra prediction mode using border pixels on borders between a current macroblock to be coded and adjacent macroblocks and generating a predicted macroblock corresponding to the current macroblock in the determined intra prediction mode; a subtractor outputting a difference between the current macroblock and the predicted macroblock; a transformation/quantization unit transforming the difference into a frequency band signal and quantizing the frequency band signal; and a coding unit coding a quantization result.
