IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM IN WHICH BITSTREAM IS STORED

An image encoding/decoding method and device are provided. An image decoding method according to the present invention can comprise the steps of: restoring an MFM indicator for indicating whether an intra prediction mode of a current block is a predetermined intra prediction mode; deriving the intra prediction mode of the current block on the basis of the MFM indicator; and generating, on the basis of the intra prediction mode, a prediction block of the current block by performing intra prediction on the current block. 提供了一种图像编码/解码方法和装置。根据本发明的图像解码方法可包括以下步骤：重建用于指示当前块的帧内预测模式是否为预定帧内预测模式的MFM指示符；基于MFM指示符，推导当前块的帧内预测模式；并且基于所述帧内预测模式通过对当前块执行帧内预测来生成当前块的预测块。
