Abstract
An image encoding method and apparatus, and an image decoding method and apparatus respectively corresponding to the image encoding method and apparatus are provided. The image encoding method includes: if a current block is an initial block of a current slice, determining whether a virtual block in which pixel values are equal to a predetermined value is identical to the current block; and encoding the current block in a first mode based on the determining, wherein the first mode is a mode for encoding information representing that the current block is encoded in the first mode, instead of encoding pixel values of the current block, when the current block is identical to the virtual block.
