Abstract
An image encoding/decoding method and device are provided. The image encoding method of the present disclosure comprises the steps of: acquiring, from a bitstream, transform coefficient distribution information of a neighboring block; direction-adaptively determining an intra prediction mode of the current block to be decoded according to the transform coefficient distribution information of the neighboring block; and restoring the current block on the basis of the determined intra prediction mode, wherein the direction-adaptively determining step includes a step of determining similar flag information corresponding to the neighboring block on the basis of the transform coefficient distribution information of the neighboring block.
