Abstract
PURPOSE:To attain the reading of codes which a man has drawn by calculating the central coordinates of respective square with cross-shaped codes from relative position relation between reference lines and a code matrix and reading the codes of respective meshes from the center. CONSTITUTION:The coordinates of four corner parts C1-C4 of the reference lines are obtained from the reference lines 3 arranged on the periphery of the code matrix 2. Next, the central coordinates of the square with cross-shaped codes 1, 1 can be obtained from the position relation between the coordinates of four corner parts and the square with cross-shaped codes. The central coordinates of four meshes of the square with cross-shaped codes 1, 1 are obtained from said coordinates and square areas with said coordinates as a center, namely, the values of respective meshes are read, whereby codes are decoded. Thus, the codes can be manually drawn and the positions of respective meshes can accurately be read even if the picture of the square with cross- shaped codes is shifted in a rotational direction.
