Abstract: The present invention relates to image encoding and image decoding. A method for encoding images according to the present invention comprises the steps of: acquiring division information from peripheral blocks of an encoding target block with respect to the peripheral blocks; predicting the division of the encoding target block on the basis of the acquired division information; encoding information on the difference between the practical division information of the encoding target information and the predictive division information predicted in the predicting process; and transmitting the encoded information. The present invention can encode/decode the division information of the encoding/decoding target blocks using the information about the peripheral blocks.
