Abstract

The present invention relates to a method for encoding image information, to a method for decoding same, and to an apparatus using the methods. The method for decoding the image information according to one embodiment of the present invention comprises the steps of: dividing a prediction area into a first prediction area and a second prediction area according to an intra-prediction mode; performing intra prediction on, and restoration of, the first prediction area; and performing prediction on, and restoration of, the second prediction area. In the step of performing prediction on, and restoration of, the second prediction area, intra-prediction on the second prediction area can be performed with reference to a reference sample for the first prediction area or with reference to a predetermined sample in the restored first prediction area.
