Abstract:
Disclosed are methods, apparatuses, and systems for encoding and decoding an image. The present invention provides an intra prediction unit that receives an input image, calculates a correlation between a Luma area block and Chroma area block in the input image in intra prediction, removes high frequency ingredients by low-pass filtering an encoded luma pixel based on the calculated correlation, and generates a prediction block by applying an LM chroma mode, which is an extended chroma mode technique, to the luma pixel removed therefrom the high frequency ingredients.

Claim (Index 1):
An image encoding apparatus, comprising:\n an intra prediction unit receiving an input image, calculating a correlation between a Luma area and Chroma areas in intra prediction, removing high frequency ingredients by low-pass filtering luma area including an encoded luma pixel based on the calculated correlation, and generating a prediction block by predicting a chroma pixel by applying an LMchroma mode, wherein the LM chroma mode which is an extended chroma mode technique is applied to the Luma pixel removed the high frequency ingredients of the encoded luma pixel.
