Image analyzing apparatus that identifies barcode image in target image

A non-transitory computer readable storage medium storing a set of program instructions for an image analyzing apparatus, the image analyzing apparatus including a processor, the program instructions, when executed by the processor, causing the image analyzing apparatus to perform:

• acquiring target image data that is generated by executing reading of an original sheet containing a one-dimensional barcode, the one-dimensional barcode being composed of a plurality of bars having two or more different widths, the two or more different widths including a first width, the target image data representing a target image containing a background area representative of a background in the original sheet and a non-background area representative of an area other than the background;
• identifying a barcode image that is part of the target image and represents the one-dimensional barcode;
• and
• executing an output process with respect to the identified barcode image;
• the identifying a barcode image includes:
• determining a bar candidate area in the target image, the bar candidate area representing a candidate for a bar having the first width, the bar candidate area containing a feature-matching area that matches a feature concerning the two or more different widths of the bars in the one-dimensional barcode;
• searching for a first blank area and a second blank area at a first side and a second side, respectively, of the bar candidate area with respect to a specific direction, each of the first and second blank areas being part of the background area and having a length in the specific direction longer than or equal to a threshold value;
• when the first blank area is found at the first side of the bar candidate area, determining, as a first end position of the one-dimensional barcode, a boundary between the first blank area and a non-background area that is at a second side of the first blank area and is adjacent to the first blank area;
• when the second blank area is found at the second side of the bar candidate area, determining, as a second end position of the one-dimensional barcode, a boundary between the second blank area and a non-background area that is at a first side of the second blank area and is adjacent to the second blank area;
• and
• by using the first end position and the second end position, identifying an area containing the bar candidate area as the barcode image.
