Abstract
In an image analyzing apparatus, identifying a barcode image includes: determining a bar candidate area representing a candidate for a bar having a first width in a target image, the bar candidate area containing a feature-matching area that matches a feature concerning two or more different widths of bars in a one-dimensional barcode; searching for first and second blank areas having lengths longer than or equal to a threshold value at first and second sides of the bar candidate area in a specific direction; when the first or second blank area is found, determining, as a first or second end position of the one-dimensional barcode, a boundary between the first or second blank area and a non-background area; and by using the first and second end positions, identifying an area containing the bar candidate area as the barcode image.
