1. method, be used to use data handling system, all pixels are divided to M non-intersect bunch tree construction in the establishment digitizing coloured image from the digitizing coloured image with N different colours, wherein, M is less than or equal to N, each color in N different colours digitally represented by a plurality of P bit bytes in the palette, and the P bit in each P bit byte from the highest effectively to minimum effective arrangement, this method comprises:

  • (a) provide the root node that comprises all N different colours;

    (b) provide the first order brotgher of node that links to each other with root node, wherein, by the value of data handling system, give interdependent node in the first order brotgher of node with each color assignment in N the different colours according to first bit of each the P bit byte in described a plurality of P bit bytes;

    (c) for comprising more than each node in a kind of k level node of color, the place provides a plurality of brotghers of node in the k+1 level, wherein by the value of data handling system according to the k+1 bit of each the P bit byte in described a plurality of P bit bytes of this color, give the relevant brotgher of node in a plurality of brotghers of node of k+1 level with each color assignment in this node, make and have the different leaf nodes that only comprise this color for every kind of color in N the different colours;

    And(d) selection and merging leaf node are till only being left M leaf node.
