An image signal decoder including a DC component correction processing section which inputs inverse transformed DC data X as direct current components of IDCT signals and produces DC component correction data Yn for correcting the inverse transformed DC data X of a target block in process using stored DC components RD corresponding to adjacent blocks of a target block image, resulting in reducing block distortion noises of an decoded image of compressed codes to improve image quality on visual evaluation and to make a large capacity image memory for storing the decoded image disused.
