  • Publication number: 20090097567
    Abstract: An encoding apparatus includes: an orthogonal transformation unit configured to orthogonally transform image data of a predetermined block size; a binarization unit configured to binarize the image data outputted from the orthogonal transformation unit; an arithmetic encoding unit configured to arithmetically encode the binary data generated by the binarization unit; and a prediction unit configured to predict, from the binary data, whether or not the amount of arithmetically encoded data generated by the arithmetic encoding unit exceeds a permissible maximum code amount based on a predetermined encoding standard. The encoding apparatus performs, when the prediction result is that the amount of arithmetically encoded data exceeds the maximum code amount, control to prevent the arithmetic encoding by the arithmetic encoding unit from being performed to the binary data corresponding to the prediction result.

  • Publication number: 20050250907
    Abstract: Conventionally, a maleic acid-modified polypropylene oligomer has been used as a dispersant of clay in resins, and a hydroxy-modified polypropylene containing a hydroxyl group has been known as a resin modifier for improving the coatability of resins. But a dispersant or coatability improver having the clay dispersion effect and coatability improving effect for resins with as small amount of addition without decreasing the resin properties has not been known. The present invention provides a modifier for resins which comprises a dispersant (I) or a coatability improver (II) comprising a modified polyolefin (A) containing a hydrophobic group comprising a polyolefin (a) having a number average molecular weight of 1,500 to 100,000 and 0.2 to 10 double bonds per 1,000 carbons at the molecular terminus and/or within the molecule, and a hydrophilic group containing at least one onium base (b), and a number average molecular weight per (b) being 750 to 50,000, and a filler in combination.
