JPEG2000 is the latest ISO/IEC standard for still image coding. Its core part has already been published as an international standard (IS), and work on its subsequent parts is under way. In this paper author's encoder implementation compilant with core part of JPEG2000 will be presented, as well as result of comparison between presented JPEG2000 encoder implementation and two publicly available JPEG and JPEG-LS implementations. Also, mains features of JPEG2000 standard in comparison to somewhat older JPEG and JPEG-LS international standards will be briefly described.
