Abstract (en)
[origin: WO2007071678A1] An image is broken down in a colour breakdown space. For each broken down source pixel (E<SUB>S0j</SUB>), if a source point P<SUB>S0j</SUB> is used to represent the end of the colour source vector OP<SUB>S0j</SUB> associated with said source pixel (E<SUB>S0j</SUB>), component points P<SUB>1j</SUB>, P<SUB>2j</SUB>, ..., P<SUB>kj</SUB> , P<SUB>nj</SUB> are used to represent the ends of the colour component vectors OP<SUB>1j</SUB>, OP<SUB>2j</SUB>, ..., OP<SUB>kj</SUB>, ..., OP<SUB>nj</SUB> associated with component pixels (E<SUB>Clj</SUB>, E<SUB>C2j</SUB>, ..., E<SUB>Ckj</SUB>, ..., E<SUB>Cnj</SUB>), and if a boundary sphere having radius L<SUB>S0j</SUB> and centred on point P<SUB>S0j</SUB> is defined, then said breakdown is such that P<SUB>S0</SUB>P<SUB>j1</SUB>, P<SUB>S0</SUB>P<SUB>j2</SUB>, P<SUB>S0</SUB>P<SUB>jk</SUB>. , P<SUB>S0</SUB>P<SUB>jn</SUB> = K<SUB>S0j</SUB> x L<SUB>S0j</SUB>, where K<SUB>S0j</SUB> > 0,5. The blurring effectiveness is thus substantially enhanced.
