Abstract
Provided are an image encoding method and apparatus, in which a distribution of difference values included in an image unit is adjusted using a predetermined offset, an image unit including the adjusted distribution of the difference values is divided into an image plane corresponding to upper bits and an image plane for lower bits, and then the image planes are entropy-encoded.
