Abstract
An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus may comprise obtaining a current block by splitting an image, determining prediction mode characteristic information based on encoding information of the current block, determining a prediction mode type of a lower-layer block split from the current block based on the prediction mode characteristic information, obtaining the lower-layer block by splitting the current block, and decoding the lower-layer block based on the determined prediction mode type of the lower-layer block. The prediction mode characteristic information may be determined based on a color format of the current block.
