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

An image decoding method is disclosed in the present specification. The image decoding method of the present invention comprises the steps of acquiring, from a bitstream, the prediction information and the residual signal information about a current block; and restoring the current block on the basis of the acquired prediction information and the acquired residual signal information, wherein the prediction information is acquired through entropy decoding, and a context model to be used for the entropy decoding of the prediction information is determined on the basis of a prediction mode of a neighboring block of the current block. 在本说明书中公开了一种图像解码方法。本发明的图像解码方法包括以下步骤：从比特流获取关于当前块的预测信息和残差信号信息，并且基于获取的所述预测信息和获取的所述残差信号信息恢复当前块，其中，所述预测信息是通过熵解码被获取的，并且基于当前块的邻近块的预测模式确定用于对所述预测信息进行熵解码的上下文模型。
