Methode zur Bilddekodierung mit Kodes variabler Länge

摘要

In an image coding method, a variable length coding process for the quantized DCT coefficients is performed using a variable length code table. If the comparison process between an event ("Last", "Run","Level") derived from the coefficients and a reference event included in the code table does not find a match, a prescribed transformation eg. adding an offset value is applied and a second variable length coding process is performed. If the second run does not find a match either, a fixed length code is used. <IMAGE>
