PREDICTION METHOD AND APPARATUS FOR CHROMA COMPONENT OF IMAGE USING LUMA COMPONENT OF IMAGE |
摘要 |
Disclosed are a method and an apparatus for predicting a chroma signal from a luma signal using the correlation between a luma signal and a chroma signal. The prediction method for a chroma component of an image, according to the present invention, comprises: generating a down-sampled luma signal that matches a chroma signal by considering a size difference between the luma prediction unit, which corresponds to the color format, and the chroma prediction unit, and by executing a variety of sampling methods on the basis of location of each luma pixel; and predicting the chroma signal from the down-sampled luma signal. |
