Abstract: The present invention discloses an image encoding method and device that generates a first predictive encoding unit for the current encoding unit to be encoded, that generates a second predictive encoding by changing the pixel value of each pixel of the first predictive encoding unit using each pixel constituting the first predictive encoding unit and at least one peripheral pixel, and that improves the prediction efficiency of images by encoding the value of the difference between the current encoding unit and the second predictive encoding unit, and a decoding method and device therefor.
