PURPOSE:To provide the affine transformation arithmetic method and the affine transformation arithmetic circuit device without the preprocessing in case of computing affine transformation formulas. CONSTITUTION:The affine transformation arithmetic circuit is used for the three-dimensional image processing by executing the 3X3 matrix operation and the parallel displacement operation. It is provided with a 1st storage means 7 storing the information for the 3X3 matrix operation, 3nd storage means 8 storing the information for the parallel displacement operation, multiplexers 10 and 13 performing the multiplication between the original image processing information where the prescribed processing is performed on the original image input coordinate information and the information for the 3X3 matrix operation, and adder 15 adding the output information of the multiplexer and the information for the parallel displacement operation. |
