With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. Despite of the good points of the JPEG2000, however, what has not been widely deployed is a problem of high complexity. Comparison with the JPEG is sure that the JPEG2000 has excellent compression efficiency, but this became difficult technology for even practical use at PC because of high complexity. After minimizing all high complexity that can be minimized, it is the first prerequisite for applied product development. In this paper, we propose an optimization technique of the JPEG2000 to reduce high complexity. Using proposed method we will materialize the JPEG2000 decoder on PDA.
