Abstract
An image of a region is taken which includes a two-dimensional code. A two-dimensional code area is determined in the image. The two-dimensional code area corresponds to the two-dimensional code. Inspection lines are set which connect opposite sides in two pairs among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a cell matrix type. Inspection lines are set which connect opposite sides in one pair among four sides indicating boundaries of the two-dimensional code area in cases where the two-dimensional code is of a bar-code stack type. Information is read from the two-dimensional code area on the basis of the inspection lines. Division points are set on the opposite sides in response to a ratio in length between sides adjacent to the opposite sides and a number of arrangements of cells in the two-dimensional code in cases where the two-dimensional code is of the cell matrix type. Division points are set on the opposite sides in response to a ratio in length between sides adjacent to the opposite sides and a number of stacked bar codes in the two-dimensional code in cases where the two-dimensional code is of the bar-code stack type. The inspection lines are set which connect corresponding ones of the division points.
