Abstract
A digital image decoding apparatus wherein image coded in accordance with an image coding method adopting the discrete cosine transform (DCT) are decoded without generating blocking picture components. In the apparatus, a data decoder performs the inverted discrete cosine transform (IDCT) for the image data coded in accordance with the coding method adopting the DCT to decode original image data. A selective filter selectively filters the decoded image data from the data decoder, thereby eliminating the blocking picture components.
