ABSTRACT:
A 2-dimensional code reading apparatus includes a code position detector receiving an input image that is formed by optically reading 2-dimensional codes, and extracting a 2-dimensional codes from the input image. A data acquisition unit acquires identification information of a document page and positional information of the 2-dimensional codes on the document page, from the 2-dimensional codes. A data decoder performs decoding of the identification information and the positional information. The code position detector is provided with a code frame detector detecting a code frame which defines a fixed region of the 2-dimensional codes, and determining a dot of a target pixel as being a corner dot of the code frame.
