According to one embodiment of the present invention, the image encoding and decoding apparatus comprises: an image encoder which reduces horizontal and vertical sizes of a variable macro block into the set size or ratio so that the variable macro block may be reset in a smaller size than the current size, if the variable macro block of the current encoding target is not positioned inside an input image, and performs a prediction encoding process on the basis of the reset variable macro block; and an image decoder which performs a decoding process by reducing the size of a variable macro block of the current decoding target into the set size or ratio so that the variable macro block may be reset in a smaller size than the current size, if the variable macro block of the current decoding target is not positioned inside an input image.

Disclosed are an image encoding/decoding device and method. According to an embodiment of the present invention, the image encoding/decoding device comprises: an image encoder which encodes, on the basis of additional information about divided sub blocks and a macro block of an image, a differential value between a quantization parameter value of the macro block and a quantization parameter value of divided blocks within an extended macro block; and an image decoder which restores the differential value of the quantization parameters encoded by the image encoder, restores residual blocks on the basis of the restored differential value of the quantization parameters, and restores an image on the basis of the restored residual blocks.
