Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus includes determining a splitting type of a current block, splitting the current block into a plurality of lower-layer blocks based on the splitting type, and decoding the lower-layer blocks. In this case, the current block may be a chroma block, and the determining the splitting type of the current block may be performed by disallowing a predetermined type, in which a width or height of the lower-layer blocks is a predetermined value, among a plurality of splitting types.
