Abstract
PURPOSE: To perform a transformation process at a high speed by providing a two- dimentional hadamard's transformation method for pictures.
CONSTITUTION: An original picture, regarded as matrix [A] of N rows by N columns, is stored in the 1st screen memory FM2. Then, N-order Hadamard's matrix [H] of N rows by N columns is stored in the 2nd screen memory FM3. According to Hadamard's matrix [H] in screen memory FM3, original picture [A] in screen memory FM2 is integrated by arithmetic circuit ALU and transformation picture [B] is stored in screen memory FM1. Next, transposed matrix [Bt] is obtained with read-out address of screen memory FM1 made inverse to write addresses and integrated, according to Hadamard's matrix [H], by arithmetic circuit ALU to obtain a transform picture, which is stored in screen memory FM2 . Contents of screen memories FM1 to FM3 can be displayed on cathode-ray tibe by being selected by alternation switch S.
