Patent number: 5555321Abstract: A method and device for decoding received coded image data for image compression in moving picture telecommunication, wherein data are subjected to discrete cosine transformed coded compression to enhance decoding processing performance. To reproduce high precision moving pictures, positional information within an image block is scanned by a run/level dividing device from run values of the received data composed of the combination of run values and level values. Each pair of run and level values are subjected to a reverse quantifying process to form pairs of position and level values wherein the positional information and the level values correspond to each other. The level values are transformed into positional information using the zigzag scan and are also reverse quantified. A reverse discrete cosine transforming device carries out processing of the reverse quantified data to decode the image data.Type: GrantFiled: May 25, 1994Date of Patent: September 10, 1996Assignee: Fujitsu LimitedInventors: Hirokazu Ogura, Kazuo Kaneko, Tadayoshi Kono
