摘要

In a decoding process of a read image of a MaxiCode symbol, the present invention is characterized in that in the decoding process of a read image of a MaxiCode symbol, a search of a finder pattern of a read image in which a symbol of a two-dimensional code is read, a search of a direction module, Dimensional code reading method, an information recording medium, and a two-dimensional code reading apparatus.;To this end, in the data module search process in the decoding process of the maxicode symbol, the present invention first assumes a directional axis passing through the center point of the finder pattern, the center point of the inward direction module and the center point of the outward direction module, And calculates position information and graphic information of the data module (step S1801). Next, based on the pixel data corresponding to the position of the calculated center point of each module, the bit pattern is converted into a bit pattern composed of "black" = bit 1 or "back" = bit 0 (S1802). Next, the position information of the data module of the maxicode symbol existing in the area between the directional axes is calculated (step S1803). Next, based on the pixel data corresponding to the position of the calculated center point of each module, it is converted into a bit pattern composed of "black" = bit 1 or "back" = bit 0 (S1804), and the data module search process is terminated Respectively.
