Image processing device and image processing method

An image processing device to perform image processing, comprising:

• a two-dimensional image being formed of a group of pixel data which are a matrix of plural pixel data, wherein said group of pixels are divided into small blocks formed of a plurality of said pixel data, a plurality of said small blocks form a large block, and in each of the large block each of the small blocks is defined and arranged by certain rules, said image processing device comprising:
• a plurality of storages, in which each of said small blocks located according to said rules forming each of said large blocks has said pixel data independently, and by specifying an address assigned to each small block, a plurality of pixel data in a pertinent small block is simultaneously read out;
• a calculator comprising a coefficient matrix in which a matrix of plural coefficients are arranged, so that said plural coefficients are multiplied by each of respectively corresponding pixel data and summed up;
• wherein said calculator multiplies each of the pixel data in each of said small blocks forming said one large block, by said coefficient matrix rearranged in to a predetermined order, and
• wherein said small block is formed of said pixel data of m1×m2, said large block is formed of the small blocks of 11×12, said coefficient matrix is formed of said coefficients of n1×n2, and the following equations are fulfilled:
• n1≦m1(l1−1)+1
• n2≦m2(l2−1)+1
• m1≧4
• m2≧4
• l1≧2
• and
• l2≧2.
