The present invention provides an image encoding method and an image decoding method. The image decoding method of the present invention may comprise: obtaining intra-frame prediction information of acurrent block from a bitstream; inducing an intra-frame prediction mode of the current block on the basis of the intra-frame prediction information; determining a reference region for intra-frame prediction of the current block; and performing intra-frame prediction of the current block on the basis of the intra-frame prediction mode and the reference region. 本发明提供一种图像编码方法和图像解码方法。本发明的图像解码方法可以包括：从比特流获得当前块的帧内预测信息；基于帧内预测信息得到当前块的帧内预测模式；确定用于当前块的帧内预测的参考区域；以及基于帧内预测模式和参考区域执行当前块的帧内预测。
