TECHNICAL FIELD

The present invention relates to image processing, and more particularly, to a method and an apparatus for encoding/decoding an intra prediction mode.

BACKGROUND

Recently, with the expansion of broadcasting services having high definition (HD) resolution in the country and around the world, many users have been accustomed to a high resolution and definition image, such that many organizations have conducted many attempts to develop next-generation image devices. In addition, the interest in HDTV and ultra high definition (UHD) having a resolution four times higher than that of HDTV have increased and thus, a compression technology for higher-resolution and higher-definition image have been required.

For the image compression, an inter prediction technology predicting pixel values included in a current picture from a picture before and/or after the current picture, an intra prediction technology predicting pixel values included in a current picture using pixel information in the current picture, an entropy encoding technology allocating a short code to symbols having a high appearance frequency and a long code to symbols having a low appearance frequency, or the like, may be used.
