Abstract:
1. A data processing method for converting an input sample data sequence representing image or audio data, consisting of M samples to an output sample data sequence consisting of N samples, comprising: setting values of registers representing a nonzero constant k and a prescribed parameter W; changing the value of parameter W in its register by repeatedly adding k*N to said parameter W by sequentially scanning input sample data as long as W≦0 when k>0 or as long as W≧0 when k<0; outputting said converted output sample data when W becomes larger than 0 in the case of k>0 or W becomes smaller than 0 in the case of k>0 as a result of said repeated adding; and subtracting a value stored in a register representing k*M from a value stored in a register representing said W, wherein said repeatedly adding, outputting and subtracting are repeated until said N output sample data have been output, thereby converting an input sample data sequence representing image or audio data consisting of M samples to an output sample data sequence consisting of N samples.
