1. A method of encoding an image, the method comprising:

  • performing motion estimation on a current block to be encoded and determining a prediction mode of the current block;

    when the determined prediction mode of the current block is a skip mode, determining whether prediction modes of neighboring blocks of the current block are skip modes;

    when it is determined that the prediction modes of the neighboring blocks are skip modes, encoding a residual that is a difference value between the current block and a prediction block of the current block; and

    adding the residual to a bit stream that is generated by encoding the image.
