Abstract

The present invention relates to a spatial prediction apparatus and a predicting method thereof, an image encoding device and method using same, and an image decoding device and method using same. The image encoding device according to embodiments of the present invention comprises: a spatial prediction execution unit which predicts a target block using a directional intra prediction mode and a template matching mode and selects the most inexpensive mode based on rate distortion; and an integer conversion execution unit for executing integer conversion for the residual signals of the images predicted through the template matching mode when the template matching mode is selected by the spatial prediction execution unit. The present invention can enhance the accuracy and efficiency of the intra prediction and can minimize an increase of overhead in the video encoding.
