Abstract:
An image decoding method for extracting a variable length code from compression-coded data, obtaining an event corresponding to said variable length code by using a variable length code table wherein a reference event consisting of Last, Run, Level, is assigned to each reference variable length code, and deriving an output transform coefficient from said event, the method comprising:obtaining an event corresponding to said variable length code by using said variable length code table when said variable length code does not include a control code, and obtaining an event corresponding to said variable length code by using said variable length code table and then obtaining a transformed event by transforming the Run value of said event corresponding to said variable length code using a predetermined function when said variable length code includes said control code followed by a third mode code, and wherein the control code is â€œ0000011â€  and the third mode code â€œ10â€ .
